Question 14.
What are the difference between the Weather and Climate?
Answer:

Weather	Climate
It is the study of atmospheric conditions for a short period of time.	It is the study of the average weather condition observed over a long period of time.
It is short term phenomenon	It is a long term phenomenon
Weather changes frequently	It does not change frequently
It depends on a smaller areas like district or state	It depends on a larger area like state or country

Question 15.
What are the main differences between short waves and long waves?
Answer:
Energy is radiated in the form of short waves from hotter objects. Due to high frequency, the short waves traverse through the atmosphere without obstruction. Objects with relatively less heat radiate energy in the form of long waves. Due to low frequency, long waves will be absorbed or reflected by the atmospheric particles.

Question 16.
What is Terrestrial Radiation? How does this affect atmospheric temperature?
Answer:
The re-radiation of energy in the form of long waves from the earth’s surface is called Terrestrial radiation. The absorption of terrestrial radiation by the atmospheric gases such as carbon dioxide heats up the atmosphere. This phenomenon is tenned as Green House Effect.

Question 17.
Explain Conduction, Convection, Advection.
Answer:
Conduction: Heat is transferred to the lower part of the atmosphere which is directly in contact with the
surface of the earth.

Convection: As the heated air expands and rises up, heat is transferred to higher reaches of the atmosphere. Advection: Heat is transferred horizontally through wind.

Question 18.
When is the maximum and minimum temperature recorded in a day? Why?
Answer:
The temperature recorded at 2pm is considered as the maximum temperature of the day by the meteorologists. The surface temperature of the earth gradually decreases in the afternoon due to the decrease in intensity of insolation as well as the simultaneous terrestrial radiation. The earth’s surface as well as the atmosphere get cooled by more energy loss through terrestrial radiation during night. Thus the temperature recorded just before the sun rise is considered as the minimum temperature of the day.

Question 19.
What are the Isotherms? What is the significance of these in the study of climate?
Answer:
Data regarding the temperature are being utilized for climatic studies and further analysis. Plotting the temperature recorded at specific places, smooth curved lines are drawn connecting the places having equal temperature. These imaginary lines are called Isotherms. Isotherm maps are very useful for analysing temperature distribution.

Question 20.
How is the Equatorial Low Pressure Belt formed? What is the specialty of this belt?
Answer:
The expansion and rising up of air due to high temperature prevailing in the equatorial region is the cause for the formation of Equatorial Low Pressure Belt. This zone of vertical air currents is devoid of winds. Being the windless zone, this pressure belt is called Doldrum.

Question 21.
How are the south-west monsoon winds formed? W hat is the significance of these in India?
Answer:
During summer the South Asian land masses, especially the Indian Sub Continent, gets heated up intensely and severe low pressure develops. Wind blows towards the land mass from the Indian Ocean where comparatively high pressure prevails. These winds blowing as South West winds due to Coriolis effect causes widespread rainfall on entering the land. This is South west monsoon. This south west monsoon is the main reason for the rainy season in India.

Question 22.
What is relative humidity? How is this calculated?
Answer:
The ratio between the actual amount of water present in the atmosphere and the total waterholding capacity of atmosphere at that particular temperature and time is referred to as Relative Humidity. It is expressed in percentage.
Relative Humidity = \(\)\frac{\text { Absolute Humidity }}{\text { Total water holding capacity of the atmosphere }}\(\) × 100

Question 23.
Explain how the Coriolis force affects the direction of winds. (FIRST TERM 2023)
Answer:
One of the major factors influencing the direction of winds is the Coriolis Force. Owing to the Coriolis effect, the winds will deflect towards the right of its direction in the Northern Hemisphere and towards the left of its direction in the Southern Hemisphere.

Question 24.
What is atmospheric pressure? What are the main factors influencing the atmospheric Pressure?
Answer:
The weight exerted by the atmospheric air over the earth’s surface is termed as Atmospheric Pressure. Barometer is the instrument used to measure atmospheric pressure.
Factors affecting atmospheric pressure are:

• Temperature: Atmospheric air expands on getting heated, and rises up. Thus low pressure regions are formed. This rising air gradually cools, contracts and subsides to form high pressure regions.
• Altitude: As the density of atmospheric gases decreases with increase in altitude, atmospheric pressure gradually decreases. The vertical variation of atmospheric pressure is at the rate of about lmb per 10 metres.
• Humidity: As the humidity increases, the water molecules displace the heavier gases in the atmosphere like nitrogen and oxygen. The atmospheric pressure becomes low, as humid air is lighter than dry air.

Question 25.
How is energy produced in the sun? What is the amount of solar energy reaching the Earth?
Answer:
Sun is the sole source of energy for the earth. Energy is produced in the sun by nuclear fusion. Massive amount of energy continuously produced in the sun through nuclear fusion is emitted in the form of short waves. Only a small amount of energy radiated from the sun reaches the earth’s surface (approximately one part of 200 million). The amount of sun’s rays reaching the earth’s surface is called Insolation.

Question 26.
What is earth’s heat budget? How does this help in maintaining earth as a living planet?
Answer:
Almost entire energy reaching the earth as insolation is radiated back every day Thus the surface temperature of the earth remains balanced without becoming extremely hot or cold. This process of heat balancing is called the Heat Budget of the Earth. Consider the total amount of solar energy reaching the top of the atmosphere of the earth as 100 units. Out of this, 35 units will be reflected back and 14 units will be absorbed by the atmospheric particles. The total amount of energy reaching the surface of the earth is estimated as 51 units. Out of this, 34 units will be transferred to the atmosphere through the processes of heat transfer such as conduction and convection. By re-radiating 17 units of energy directly from the earth’s surface and 48 units from the atmosphere, the entire energy received by the earth and its atmosphere gets sent back.

Question 27.
How winds are formed? What are the factors that influence wind direction and speed?
Answer:
Winds are the horizontal movements of air from high pressure areas to low pressure areas.

• One of the major factors influencing the direction of winds is the Coriolis Force. Owing to the Coriolis effect, the winds will deflect towards the right of its direction in the Northern Hemisphere and towards the left of its direction in the Southern Hemisphere.
• The speed and intensity of winds are influenced mainly by two factors.
• Pressure gradient is the change in pressure over a horizontal distance. If there is considerable change in pressure between nearby places, it indicates high pressure gradient. If there is no considerable difference of pressure over horizontal distance, pressure gradient is said to be low. At places where there is high pressure gradient, winds will be strong.
• The friction caused by hills, mountains, forests and man-made structures will obstruct the free flow of winds.

Question 28.
What are Periodic winds? Explain with examples.
Answer:
Winds subjected to the periodic reversal of their direction are termed as Periodic winds. Diurnal winds such as the land breezes, sea breezes, mountain breezes and valley breezes, as well as the monsoon winds which repeat in summer and winter, are periodic winds.

a) Permanent Winds
The winds blowing constantly over a particular direction throughout the year are called Permanent winds. These winds are also known as prevailing winds and planetary winds. These winds blow between global pressure belts. Trade winds, Westerlies and Polar winds are the major permanent winds.

ITCZ
The equatorial low pressure region where the trade winds from the Northern Hemisphere and the Southern Hemisphere converge is known as Inter Tropical Convergence Zone (ITCZ). ITCZ shifts with the apparent movement of the sun.

b) Periodic Winds: Winds subjected to the periodic reversal of their direction are termed as Periodic winds. Diurnal winds such as the land breezes, sea breezes, mountain breezes and valley breezes as well as the monsoon winds which repeat on summer and winter are periodic winds.

Land Breezes and Sea Breezes
The air in contact with the land also gets heated up and ascends as the land heats up quickly during the daytime. This leads to the formation of low pressure over the land which causes the comparatively cooler air to blow from the sea. This is known as sea breeze.

As the land cools faster than the sea during the night it would be high pressure over the land and low pressure over the sea. This results in the movement of air from the land to sea. This is the land breeze.

Mountain Breezes and Valley Breezes
During night, air along the mountain slopes cools, contracts and moves down slope. These winds are called mountain breezes. During day time, the heating by sunlight and rising up of air along the mountain slopes make the wind to blow up slope from the valley. These winds are called valley breezes.

Monsoon Winds
• The term ‘monsoon’ implies the seasonal reversal in the wind pattern.
During summer the South Asian land masses, especially the Indian Sub Continent, gets heated up intensely and severe low pressure develops. Wind blows towards the land mass from the Indian Ocean where comparatively high pressure prevails. These winds blowing as South West winds due to Coriolis effect causes widespread rainfall on entering the land. This is Southwest monsoon.

During winter, as the northern land masses get severely cooled, high pressure develops over North India. This causes the winds to blow continuously from the land towards the Indian Ocean as north east winds.

c) Local Winds: Local winds are winds formed as a result of local differences in temperature and pressure in different parts of the world. Most of the local winds are periodic in nature. These winds are known by local regional names. Details regarding a few such local winds:

Local Winds	Region	Characteristics
Loo	North Indian Plains	Hot wind
Chinook	Slopes of Rocky Mountains in North America	Dry hot wind
Foehn	Slopes of Alps Mountain in Europe	Dry hot wind
Harmattan	Sahara Desert in Africa	Relief to intense heat

d)Variable Winds: Winds of short duration, of which the intensity or direction cannot be predicted are called variable winds. Cyclones and Anticyclones belong to this category.

Cyclones
• Cyclones are low pressure systems towards which winds whirl from the surroundings.
Even if the cyclones developed over the tropical region are comparatively lesser in diameter, they are devastative than temperate cyclones. Tropical cyclones originate over tropical oceans. The tropical cyclones moving in northwest direction over the oceans, get dissipated on hitting the lands. Different temperature conditions prevailing on land and also the friction causes the dissipation of cyclones on entering land.

The tropical cyclones cause intense rainfall and strong whirlwinds along the coasts. They are known by different names in different parts of the world such as Hurricanes, Typhoons, Willy Willies, Tornadoes etc. Temperate cyclones are formed in temperate regions where warm and cold air masses meet. Even if the temperate cyclones are larger in diameter, they are less devastative. Unlike the tropical cyclones, these low-pressure systems can move over land also. The direction of flow of air into the cyclones are anticlockwise in the Northern Hemisphere and southern Hemisphere clockwise in the Southern Hemisphere.

Anticyclones

• Anticyclones are high pressure system from which winds whirl outwards. Generally anticyclones do not cause atmospheric disturbances.
• The direction of flow of winds from anticyclones is clockwise in the Northern Hemisphere and anticlockwise in the Southern Hemisphere.

Question 29.
What is Humidity? What is the difference between Absolute Humidity and Relative Humidity?
Answer:
The invisible water content in the atmosphere is called Humidity.

• Actual amount of water vapour present per unit volume of atmosphere is called Absolute humidity. Hygrometer is the instrument used to measure atmospheric humidity.
• The ratio between the actual amount of water present in the atmosphere and the total waterholding capacity of atmosphere at that particular temperature and time is referred to as Relative Humidity. It is expressed in percentage.
• Relative humidity can be estimated based on the difference in temperature recorded in wet and dry bulb thermometers.
• Relative Humidity = \(\)\frac{\text { Absolute Humidity }}{\text { Total water holding capacity of the atmosphere }}\(\) × 100
  Total water holding capacity of the atmosphere

Valley Breeze	During day time, the heating by sunlight and rising up of air along the mountain slope.
Land Breeze	At night the pressure blows from high land to sea.
Sea Breeze	During the day, it blows from the high-pressured sea

Question 32.
What is condensation? What are the different forms of condensation? Explain.
Answer:
Condensation
The atmospheric moisture is visible only when the water vapour condenses to form tiny droplets of water.

Different forms of Condensation:
a) Dew: During the night, as the earth’s surface cools down, the atmosphere close to the earth’s surface also cools. The water vapour condenses to form tiny droplets of water which may cling on to the grass tips, leaf blades as well as other cold surfaces.

b) Frost: Whenever the atmospheric temperature falls below 0° Celsius, especially during nights, tiny crystals of ice are formed instead of dew.

c) Mist and Fog: When the atmosphere gets cooled, the water vapour condenses to form tiny droplets of water and remains suspended in the lower atmosphere. Fog or mist is formed as a result of condensation of water vapour around tiny dust particles in the lower atmosphere. Fog and mist can be distinguished based on the range of visibility through them.

d) Clouds: Clouds are formed as a result of condensation around the tiny dust particles in the atmosphere. The water droplets thus formed are less than 0.001 cm in diameter. This is why, they remain suspended in the atmosphere.

Clouds can be classified based on their form as well as the height at which they are formed.

• Thin, delicate, feather-like clouds formed at very high altitudes are called Cirrus clouds.
• Thick-layered clouds, usually formed in the lower atmosphere, are called Stratus clouds.
• Cotton wool-like clouds formed as a result of intense convection currents, are called Cumulus clouds. These clouds have great vertical development.
• Dark, rain-bearing clouds, formed in the lower part of the atmosphere, are called Nimbus clouds. The dark colour is due to the thick concentration of water droplets which does not allow light to penetrate through them.
• These clouds are not usually seen independently. Mostly we see the combinations of different types of clouds. Such clouds are called as cirro stratus, strato cumulus, cumulo nimbus, nimbo stratus etc.

Question 33.
Monsoon winds are classified as southwest and northeast. Validate the statement.
Answer:
The term ‘monsoon’ implies the seasonal reversal in the wind pattern.

• During summer the South Asian land masses, especially the Indian Sub Continent, gets heated up intensely and severe low pressure develops. Wind blows towards the land mass from the Indian Ocean where comparatively high pressure prevails. These winds blowing as South West winds due to Coriolis effect causes widespread rainfall on entering the land. This is Southwest monsoon.
• During winter, as the northern land masses get severely cooled, high pressure develops over North India. This causes the winds to blow continuously from the land towards the Indian Ocean as north east winds. These winds which are generally dry in nature are called Northeast monsoon winds.

Question 34.
Explain how equatorial low pressure belt and subtropical high pressure belts are formed. Identify the planetary wind that blows between these pressure belts.
Answer:

• The expansion and rising up of air due to high temperature prevailing in the equatorial region is the cause for the formation of Equatorial Low Pressure Belt.
• The rising warm air along the equatorial region moves polewards as upper air winds which gradually cool and subside at about 30° North and 30° South latitudes. This results in the formation of Sub Tropical High Pressure Belts.
• The planetary wind that blows between these pressure belts are trade winds and westerlies.

Question 35.
What are variable winds? Distinguish between cyclones and anticyclones. (MODEL 2020)
Answer:
Winds of short duration, of which the intensity or direction cannot be predicted are called variable winds. Cyclones and Anticyclones belong to this category.

Cyclones: Cyclones are low pressure systems towards which winds whirl from the surroundings. Even if the cyclones developed over the tropical region are comparatively lesser in diameter, they are devastative than temperate cyclones. Tropical cyclones originate over tropical oceans. The tropical cyclones moving in northwest direction over the oceans, get dissipated on hitting the lands. Different temperature conditions prevailing on land and also the friction causes the dissipation of cyclones on entering land. The tropical cyclones cause intense rainfall and strong whirlwinds along the coasts. They are known by different names in different parts of the world such as Hurricanes, Typhoons, Willy Willies, Tornadoes etc. Temperate cyclones are formed in temperate regions where warm and cold air masses meet. Even if the temperate cyclones are larger in diameter, they are less devastative. Unlike the tropical cyclones, these low-pressure systems can move over land also. The direction of flow of air into the cyclones are anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Anticyclones: Anticyclones are high pressure system from which winds whirl outwards. Generally anticyclones do not cause atmospheric disturbances. The direction of flow of winds from anticyclones is clockwise in the Northern Hemisphere and anticlockwise in the Southern Hemisphere.

Question 36.
What is Precipitation? What are the different forms of Precipitation? Explain their characteristics.
Answer:
As a result of continuous condensation, the size of water droplets within the clouds gradually increases. As the size of water droplets grows beyond the limit of resistance against gravity, water droplets will be released from the clouds and may fall on earth in various forms. This is termed as precipitation. Rainfall, snow fall and hailstones are the different forms of precipitation.

• Rainfall is the common and familiar manifestation of precipitation which is in the form of water droplets.
• Temperature falls below 0° Celsius in cold climatic regions as well as in temperate regions during winter. In such places, precipitation occurs in the form of tiny crystals of ice. This form of precipitation is called snowfall.
• The water droplets released from the clouds are subjected to repeated condensation at different levels of atmosphere. It reaches the earth in the form layered ice pellets. These are termed as hailstones.

Question 37.
List out the global pressure belts. Explain any two global pressure belts. (FIRST TERM 2022,2023)
Answer:
(Refer: Topic 4)
Global Pressure Belts: Temperature is inversely proportional to pressure. Thus the lowest atmospheric pressure might be experienced in the equatorial region and the highest might be in the polar regions. The pressure should therefore increase from the equator towards the poles. But actually this is not the case. Distinct pressure conditions prevail at certain specific zones due to the influence of the rotation of the earth.

• Different pressure belts are formed along certain specific latitudinal zones. These are called Global Pressure Belts.

• The expansion and rising up of air due to high temperature prevailing in the equatorial region is the cause for the formation of Equatorial Low Pressure Belt.
• This zone of vertical air currents is devoid of winds. Being the windless zone, this pressure belt is called Doldrum.
• Atmospheric conditions along the poles are just opposite to that in equatorial region. Polar High Pressure Belts are formed as a result of the contraction and subsidence of cold air.
• The rising warm air along the equatorial region moves polewards as upper air winds which gradually cool and subside at about 30° North and 30° South latitudes. This results in the formation of Sub Tropical High Pressure Belts.
• At about 60° North and 60° South latitudes, normally high pressure zones should be formed due to lower temperature conditions. But owing to the continuous throwing up of air along these regions caused by the influence of the rotation of the earth Sub Polar Low Pressure Belts are formed.
• As the temperature conditions vary with the apparent movement of the sun, the global pressure belts are subjected to relative shifts.
• Global pressure belts may shift to about 5° to 10° northwards during summer season and shift southward during winter season. This shifting of global pressure belts has decisive influence on global climate.

The pressure differences in the atmosphere are largely noticeable through air movements. There are two types of air movements in the atmosphere.

• Air Currents: Air Currents are the vertical movements of air.
• Winds: Winds are the horizontal movements of air from high pressure areas to low pressure areas.

Question 38.
How does rain occur? Prepare a note explaining the different types of rain.
Answer:
As a result of continuous condensation, the size of water droplets within the clouds gradually increases. As the size of water droplets grows beyond the limit of resistance against gravity, water droplets will be released from the clouds and may fall on earth in various forms. This is termed as precipitation. Rainfall, snow fall and hailstones are the different forms of precipitation.

• The water droplets released from the clouds are subjected to repeated condensation at different levels of atmosphere. It reaches the earth in the form layered ice pellets. These are termed as hailstones.

Rainfall
Rainfall is the most familiar form of precipitation.

Types of Rainfall
a) Orographic rainfall or Relief rainfall.

Moisture-laden winds from the sea enter the land and will be raised along the mountain slopes. This leads to condensation and formation of rain clouds along the windward slopes of mountains. Rainfall occurring in this manner is called Orographic rainfall or Relief rainfall.

While the windward slopes of mountains get plenty of rainfall, the descending dry air makes the leeward side rainless. Such regions are called Rain Shadow Regions.

b) Convectional Rainfall

Rainfall occurs in the afternoon during summer season due to the convection process. Rainfall occuring in this manner are called Convectional Rainfall. As the convectional rainfall commonly occurs during afternoons, it is also called 4 O’Clock rains.

c) Cyclonic Rainfall.
In cyclonic systems where warm and cold air meet, the warm air will be raised up to cause condensation and rainfall. This type of rainfall is called Cyclonic Rainfall.

As the boundary lines between warm and cold air masses are known as fronts, this type of rainfall are also called Frontal Rainfall.

Illiteracy, Digital divide, Poverty.

Question 10.
Explain the role of public opinion in a democratic system.
Answer:
Democracy is a political system that ensures equal participation of all the people of a country. As a system that ensures public participation, democratic governments formulate their policies and programmes by considering the opinions and interest of the people.In a democratic system, civil society makes the mlers responsible through constant criticism.In such a society, the people are fully aware of the rights and duties of citizens. Arbitrary and dictatorial tendencies are prevented in a society with strong public opinion and the rights and freedom of citizens are protected. In a society with strong public opinion, every issue is critically evaluated and it makes political parties responsible. Public opinion, as the consolidated opinion of the people, plays a key role in democratic systems.

Question 11.
Differentiate between Media Literacy and Digital Literacy.
Answer:
Media literacy is the ability to access, analyse, evaluate, create new messages and communicate the messages received through various forms of media. Content creation and the way it shapes our perceptions and how we critically interpret news and messages are all included in this. It includes the way we shape our perceptions and critically interpret news and messages.

Digital literacy is the ability to find information from the digital world and evaluate them efficiently using digital equipment and technology. This includes basic computer knowledge, effective use of internet, navigation of digital platforms, critical evaluation of online content, cyber awareness, etc. Digital literacy is how we effectively use digital tools and technology to find out and evaluate information from digital spaces.

Question 12.
Peer group is one of the important agency to shape public opinion.Explain.
Answer:
Debates and discussions among peer group members are important factors influencing public opinion formation. Peer group members share almost common characteristics in terms of personality, attitudes and behaviour which are important factors influencing public opinion formation. They all share some common characteristics in their personal experiences and social influences. Peer group members can influence each other on the policies of the government, various social issues and political parties. Such peer group discussions are helpful in eliciting common opinions, correcting existing ones and arriving at correct opinions. This debate and discussion lead,to the formation of public opinion.

Question 13.
How do political parties influence the formation of public opinion in a democratic system?
Answer:
Political parties and their activities are at the forefront of shaping, and mobilising public opinion in the democratic system of government. Both ruling and the opposition parties play a role in shaping public opinion.The main objective of political parties is to make the public think about common public issues politically. Each political party publishes journals, pamphlets, manifestos, posters, write ups etc. to create public opinion in their favour. Along with that conference, demonstrations, rallies and seminars are all organised for the formation of public opinion. Every party tries to mobilise the people in its favour by presenting their views and ideas, and making them involved in public affairs, and ensuring participation in the electoral process. During the election campaign parties try to sway public opinion in their favour. Even after the completion of the election process, the political parties keep on campaigning on public issues. When political parties go overboard and engage in personal attacks and negative propaganda, the election commission intervenes and controls them.

Question 14.
Explain how art and literature contribute to the formation of public opinion with examples.
Answer:
“Chandalabhikshuki” by Mahakavi Kumaran Asan is a work that had a strong influence in forming public opinion against social evils based on the caste system, such as untouchability. Art, literature, and cinema of each era influence the formation of the public opinion of the times. “Patta Bakki”, “Adukkalayil Ninnu Arangathekku”, and so on were some of the plays that had a significant role in changing the social life of Kerala. Literary works of Rabindranath Tagore, Subramania Bharathi and Vallathol Narayana Menon inspired the Indian freedom movement.The art forms such as Ottanthullal, Chakyarkoothu, etc could form strong public opinion against the then existing social evils, customs, and thereby ignite social revolution. Various art forms and literary works influence our tastes and interests.

Question 15.
Media play an important role in shaping public opinion. Substantiate the statement.
Answer:
Media play an important role in shaping public opinion. News, discussions and advertising programmes available through traditional media (print media, radio and television) and new media (Digital and social media) have a great influence on people. Media can bring an issue to public attention and shape public opinion on it.

a) Newspapers: Newspapers play an important role in bringing all political and social events before the public. Newspapers are able to strengthen the democratic process by bringing current issues to the people and at the same time bring the opinion of the people to the government. Therefore, fore newspapers play a key role in shaping public opinion. The influence of newspapers help not only in forming public opinion but also in changing and diverting it according to certain interests. Sometimes some news does not necessarily have to be factual and it can mislead the public opinion. Due to vested interest, wrong news might reach people through online newspapers, etc. There is a criticism that impartial approach and accuracy in the news are not often from the side of the media.

b) Radio, Television: Radio and television are serving as a mirror to social life. While the print media considers only the literate community, radio and television play an important role in forming ideas and knowledge among the illiterate community. Radio and television play a significant role in sharing the opinions and thoughts of the people in society about various policies and programmes of the government.

c) Social media: Today, social media and all mainstream media have an important role in forming public opinion. In the modem age, almost all people in society communicate through digital platforms. Everybody should recognise such traps in the digital world. We have to acquire digital and media literacy.

Question 16.
Define Public opinion and explain the role of the given agencies in shaping public opinion.
• Social Institutions and Organisations
• Opinion Poll
Answer:
Public opinion is the general opinion of the people about the issues affecting them. It can be the position or opinion generally held by a section of society on a particular issue.

• Social Institutions and Organisations: Various social institutions and organisations working in society play a crucial role in shaping public opinion. Religious institutions, caste-religious organisations, student movements, youth movements, women’s equality movements, trade unions, human rights movements, merchant associations, environmental organisation etc. play their own role in shaping public opinion.

• Opinion polls: Opinion polls are a very effective way to gather information about public attitudes and opinions on various social, cultural, political and economic issues. A sample of population is approached for their views regarding specific issues. By using the information public opinion can be formed. There are various professional agencies working to conduct opinion polls.

Question 17.
Write the characteristics of Public opinion.
Answer:
The influence of public opinion on social life, governance and politics is enormous. Public opinion is formed when responsible citizens brings out the problems in the society to the attention of others, it is an effective social control over the government and it encourages debate that empowers democracy. Public opinion is considered as one of the essential criteria of democracy. Social and cultural background of individuals, attitude, belief, preconceptions, leadership skills, education etc are the factors that influence public opinion.

• Public opinion reflects diverse opinions.
• Public opinion is not necessarily the views and opinions of the majority of people but, is the creation of a general consensus on a topic.
• Public opinion may change with the circumstances, time and new knowledge.
• Public opinion is always formed not only on political matters but also in relation to Socio-economic and cultural matters.
• There is no fixed place from where one can express public opinion and anyone can express their opinion from any where.
• Public opinion ensures democratic communication.

Question 18.
There are some factors that hinder the formation of public opinion in society. Which are they? Explain.
Answer:
Democracy will be stronger where public opinion is strong. The limitations of democracy can be corrected and guided in the right direction with strong public opinion. However, there are some factors that hinder the formation of public opinion in society.

Illiteracy: Illiterate people have only limited knowledge about public issues. They may not have the capacity to form rational opinions.

Digital Divide: The digital divide is the gap in accessing modern information technology such as the internet, computer, and smartphone. This hinders the formation of effective public opinion.
Poverty: Groups experiencing poverty are often isolated from public affairs. Hence, they are not able to participate in the formation of public opinion appropriately.

Unhealthy political activity and lack of democracy in political parties: Partisanship in political activities and polarisation among the people are factors that hinder the formation of public opinion.
Unhealthy practices during the election campaigns: Unhealthy practices that are used to influence voters during election times often hinder the formation of real public opinion.

In addition to these, corruption, regionalism, other socioeconomic, cultural and parochial group interests, and hero worship are all factors that undermine true public opinion.

SCERT Class 10 Social Science Geography Chapter 1 Weather and Climate Notes Question Answer Kerala Syllabus

Class 10 Geography Chapter 1 Notes Kerala Syllabus Weather and Climate

Question 1.
Conduct a discussion in the class on the significance of weather studies in day-to-day human activities. Hints: Agriculture, travel/ transport, fishing, tourism.
Answer:
Agriculture: Weather studies are very important in agriculture because farmers depend on the right weather conditions to grow crops. Information about rainfall, temperature, and storms helps them decide when to sow seeds, irrigate fields, or harvest crops. Sudden changes in weather, like unseasonal rains or droughts, can damage crops, so accurate weather forecasts help farmers take preventive steps and protect their produce.

Travel/Transport: Weather has a big impact on travel and transportation. Bad weather conditions like heavy rain, fog, snow, or strong winds can delay or cancel flights, trains, and bus services. By studying weather patterns, transport departments can plan safe routes and prevent accidents. For example, during storms or cyclones, ships and flights are often rescheduled based on weather forecasts to ensure the safety of passengers and goods.

Fishing: In the fishing industry, especially for people who depend on the sea, weather forecasts are essential. Fishermen need to know about sea conditions, wind speeds, and the possibility of storms before going out to fish. Accurate weather predictions help prevent accidents and loss of life. Also, knowledge of weather and ocean currents can help in finding areas rich in fish, which supports better catch and income.

Tourism: Tourism activities are closely linked to weather. Tourists usually prefer visiting places during pleasant weather conditions. For example, beach destinations are popular during sunny seasons, while hill stations attract visitors during summer. Weather studies help tourism departments plan events and prepare for tourist seasons. They also help warn tourists about extreme weather conditions like heatwaves or snowstorms, ensuring their safety and comfort.

Question 2.
Discuss the importance of heat budget in sustaining the earth as a life supporting planet.
Answer:
The heat budget plays a vital role in sustaining Earth as a life-supporting planet. It refers to the balance between the incoming solar radiation from the Sun and the outgoing heat energy that Earth radiates back into space. This balance helps maintain a stable average temperature on the planet, which is essential for the survival of all living organisms. If the Earth absorbs more heat than it gives off, the temperature will rise, leading to global warming. On the other hand, if it loses more heat than it receives, the planet would cool down, making it difficult for life to exist. The heat budget also drives important processes like the water cycle and weather patterns, which are crucial for agriculture, drinking water, and overall ecosystem health. Therefore, maintaining a balanced heat budget is essential for keeping Earth’s environment stable and suitable for life.

Question 3.
Calculate the diurnal range of temperature and the daily mean temperature if the maximum and minimum temperatures of a place are 36°C and 28°C respectively.
Answer:
Maximum temperatures of a place = 36°C
Minimum temperatures of a place = 28°C
Diurnal Range = Maximum temperature – Minimum temperature
= 36°C – 28°C = 8°C
Daily mean temperature = \(\frac{\text { Maximum temperature }+ \text { Minimum temperature }}{2}\)
= \(\frac{36^{\circ} \mathrm{C}+28^{\circ} \mathrm{C}}{2} \)
= \(\frac{64}{2}\) = 32°C

Question 4.
Observe the given diagram. Familiarise the temperature zones and identify the latitudes between which these zones are located.

Answer:

• Torrid Zone – Between Tropic of Cancer and Tropic of Capricon
• North Temperate Zone – Between Tropic of Cancer
• South Temperate Zone – Between Tropic of Capricorn and Antarctic Circle
• North Frigid Zone – Between Arctic Circle and North Pole
• South Frigid Zone – Between Antarctic Circle and South Pole

Question 5.
Observe the given diagram. Familiarise the decrease in temperature with altitude. Estimate the temperature at 6 km altitude and label it.

Answer:
The phenomenon of gradual decrease in temperature at the rate of 6.4° Celsius per kilometre of altitude is termed as Normal Lapse Rate.
Temperature at 6 km altitude = -8.4°C

Question 6.
Why do we generally experience low temperature at places situated at higher elevations such as Ooty, Munnar and Kodaikanal?
Answer:
We generally experience low temperatures at places situated at higher elevations like Ooty, Munnar, and Kodaikanal because as altitude increases, the temperature decreases. This happens because the atmosphere becomes thinner at higher altitudes, and there are fewer air molecules to absorb and retain heat from the Sun. As a result, the air is cooler. Also, the land at higher elevations loses heat quickly after sunset, making these places even cooler, especially at night.

Question 7.
Look at the given diagram. Analyse, which place, A or B, experiences the highest diurnal range of
temperature. Give reason for your answer.

Answer:
The diurnal range of temperature will be higher in place B. The reason for this is that B is located far from the sea.

Question 8.
Diurnal range of temperature is generally low in Kerala. Why?
Answer:
The diurnal range of temperature is generally low in Kerala because it is a coastal state located along the Arabian Sea. The presence of the sea has a moderating influence on the climate, meaning it reduces the difference between daytime and nighttime temperatures. Water heats up and cools down more slowly than land, so the sea keeps the surrounding areas cooler during the day and warmer at night. As a result, Kerala experiences a relatively uniform temperature throughout the day and night, leading to a low diurnal range of temperature.

Question 9.
Why do we feel discomfort like clogging of ears while travelling to higher elevations?
Answer:
We feel discomfort like clogging of ears while travelling to higher elevations because of a sudden change in air pressure. As we go higher, the air pressure outside our body becomes lower, but the pressure inside our ears takes some time to adjust. This difference in pressure pushes on the eardrum, making it feel blocked or uncomfortable. The feeling usually goes away when the pressure inside and outside the ear becomes equal, which can happen when we swallow, yawn, or chew.

Question 10.
Coastal regions experience comparatively lower atmospheric pressure than interior locations. Why? Answer:
Coastal regions experience comparatively lower atmospheric pressure than interior locations mainly due to the influence of the ocean. Water heats up and cools down more slowly than land. During the day, the land in interior areas heats up quickly, causing the air above it to rise and create low pressure. However, in coastal areas, the sea keeps the surrounding air cooler, which leads to a more stable and relatively lower pressure system over time. Additionally, the constant evaporation of seawater adds moisture to the air, making it lighter and reducing the atmospheric pressure. This combination of temperature moderation and higher humidity contributes to the lower atmospheric pressure commonly observed in coastal regions.

Question 11.
Download the pressure distribution maps of different seasons with the help of ICT and familiarise the difference in pressure distribution.
Answer:
(Hint: Collect more pressure distribution maps by using online platforms and websites and identify the difference)

Question 12.
What is the name given to the monsoon winds blow ing towards the north east direction in India?
Answer:
The monsoon winds blowing towards the north-east direction in India are called the Northeast Monsoon or Retreating Monsoon.

Question 13.
Analyse the patterns of isobars given below and find out where the winds are strong. (Put a tick mark)

Answer:

The wind speed is higher in the marked area because here the isobars are seen closely.

Question 14.
Winds are comparatively stronger over oceans than over continents. Why?
Answer:
Winds are comparatively stronger over oceans than over continents because the smooth surface of the ocean offers less friction, allowing winds to move more freely and at higher speeds.

Question 15.
Observe the given diagram and identify the pressure belts between which each of these permanent winds blow. Make use of the diagram showing the global pressure belts also. (MODEL 2019)


Answer:

Permanent	Winds
Trade Winds	Front the Sub tropical high pressure belts to the equatorial low pressure belt
Wasterlies	From Sub tropical high pressure belt to the Sub polar low pressure belt
Polar Winds	From Polar high pressure belt to the Sub polar low pressure belt

Question 16.
Trade winds are North Easterlies in the Northern Hemisphere and are South Easterlies in the Southern Hemisphere. Why?
Answer:
Trade winds blow as North Easterlies in the Northern Hemisphere and South Easterlies in the Southern Hemisphere due to the rotation of the Earth and the Coriolis effect, which deflects winds to the right in the northern hemisphere and to the left in the southern hemisphere.

Question 17.
Westerlies are comparatively stronger in the Southern Hemisphere than in the Northern Hemisphere. Why?
Answer:
Westerlies are comparatively stronger in the Southern Hemisphere than in the Northern Hemisphere mainly due to the difference in landmass distribution. The Southern Hemisphere has vast stretches of open oceans with fewer landmasses to interrupt the flow of wind. This allows the westerly winds to blow more consistently and with greater strength. In contrast, the Northern Hemisphere has larger and more continuous landmasses, which create friction and disrupt the smooth movement of these winds. As a result, the westerlies in the Southern Hemisphere are more powerful and steady.

Question 18.
Compare the tropical cyclones with temperate cyclones and prepare a note.
Answer:
Even if the cyclones developed over the tropical region are comparatively lesser in diameter, they are devastative than temperate cyclones. Tropical cyclones originate over tropical oceans. The tropical cyclones moving in northwest direction over the oceans, get dissipated on hitting the lands. Temperate cyclones are formed in temperate regions where warm and cold air masses meet. Even if the temperate cyclones are larger in diameter, they are less devastative. Unlike the tropical cyclones, these low-pressure systems can move over land also. The direction of flow of air into the cyclones are anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Question 19.
Name the process by which water turns to water vapour?
Answer:
Evaporation

Question 20.
What are the sources through which water vapour reaches atmosphere?
Answer:
Oceans – Most important source

• Nimbus – Dark and thick → brings rain.
• Cumulonimbus – Tall, dark, stormy → brings thunder and lightning.
• Step 4: Write your Observations

Question 24.
Is hailstone a winter phenomena? Inquire.
Answer:
Hailstone is not only a winter phenomenon. The fall of the hailstone usually occurs with a strong thunderstorm accompanied by summer rain.

Question 25.
While Kerala receives Southwest monsoon rains, the western parts of Tamil Nadu receives very little rainfall. Why?
Answer:
While Kerala receives abundant southwesterly rainfall, the western parts of the neighboring state of Tamil Nadu fall into the rain shadow region, resulting in very little rainfall.

Question 26.
In equatorial climatic regions convectional rainfall is a diurnal phenomenon. Why?

INTRODUCTION

Weather and climate are important aspects of our environment that affect our daily lives, occupations, food habits, clothing, and even shelter. While weather refers to the short-term atmospheric conditions such as temperature, rainfall, humidity, and wind at a particular place and time, climate is the average pattern of weather taken over a long period in a specific region. This chapter explains important topics such as atmospheric temperature, pressure, humidity, winds, and rainfall. By learning about these elements, we can better understand how weather is formed, why it changes, and how different climates exist around the world.

Weather and Climate

• Atmospheric conditions such as temperature, pressure, wind, humidity and precipitation for a shorter period of time are termed as Weather.
• The average weather condition experienced for a longer period over a larger area is termed as the Climate.
• The atmospheric conditions of any place depend on the factors such as temperature, pressure, wind and humidity. They in turn, are influenced by the amount of sunlight available there. Hence these are called elements of weather.
• The climate of a place is determined by considering the weather conditions of about 35 to 40 years.

Atmospheric Temperature

• The amount of sun’s rays reaching the earth’s surface is called Insolation.
• Conduction, convection, advection and radiation are the major processes of heat transfer.
• The re-radiation of energy in the form of long waves from the earth’s surface is called Terrestrial radiation.
• The absorption of terrestrial radiation by the atmospheric gases such as carbon dioxide heats up the atmosphere. This phenomenon is termed as Green House Effect.
• The temperature recorded at 2pm is considered as the maximum temperature of the day
• The temperature recorded just before the sun rise is considered as the minimum temperature of the day.
• Diurnal range of temperature is the difference between the maximum temperature and the minimum temperature of a day.
• The average temperature of a day is called as Daily mean temperature.
• Plotting the temperature recorded at specific places, smooth curved lines are drawn connecting the places having equal temperature. These imaginary lines are called Isotherms.
• Degree Celsius and Degree Fahrenheit are the common units for recording temperature.
• The total energy of an object due to molecular movement is termed as Heat. It is measured in Joule.
• Degree of hotness of an object is its temperature. Temperature is recorded in units such as Degree Celsius, Degree Fahrenheit and Kelvin.
• Imaginary line connecting places with highest mean annual temperature along every longitude is termed as Thermal Equator.

Factors Influencing the Distribution of Temperature

• Latitude: Very high temperature is experienced along the equatorial regions where the incidence of sun’s rays is almost vertical.
• Owing to the spherical shape of the earth, the incidence of sun’s rays are more inclined away from the equator towards the poles.
• Altitude: Atmospheric temperature gradually decreases with increase in altitude. The phenomenon of gradual decrease in temperature at the rate of 6.4° Celsius per kilometre of altitude is termed as Normal Lapse Rate.
• Differential Heating of Land and Sea: Compared to sea, land gets heated and cooled at a faster rate. Thus thedand areas experience higher summer temperature and lower winter temperature, when compared to sea.
• Distance from the Sea: Away from the sea, the maritime influence gradually decreases to cause very high day temperature and low night temperature.
• Ocean Currents The temperature along the coastal regions is raised or lowered by the warm currents and cold currents respectively as they pass by.
• Relief: Availability of sunlight differs from one place to another in accordance with the relief.

Atmospheric Pressure

• The weight exerted by the atmospheric air over the earth’s surface is termed as Atmospheric Pressure.
• Barometer is the instrument used to measure atmospheric pressure.
• Factors affecting atmospheric pressure are Temperature,Altitude and Humidity.
• Smooth curved lines are drawn on maps to connect places having equal atmospheric pressure. These imaginary lines are called Isobars.
• The symbol ‘H’ represents High Pressure Centres and ‘L’ Low Pressure Centres.
• Different pressure belts are formed along certain specific latitudinal zones. These are called Global Pressure Belts.
• Two types of air movements in the atmosphere are Air Currents and Winds.

Winds

• One of the major factors influencing the direction of winds is the Coriolis Force.
• Owing to the Coriolis effect, the winds will deflect towards the right of its direction in the Northern Hemisphere and towards the left of its direction in the Southern Hemisphere.
• The speed and intensity of winds are influenced mainly by two factors: Pressure gradient force and Frictional force
• Permanent Winds,Periodic Winds,Local Winds and Variable Winds are the different types of Winds.
• The equatorial low pressure region where the trade winds from the Northern Hemisphere and the Southern Hemisphere converge is known as Inter Tropical Convergence Zone (ITCZ).

Humidity

• The invisible water content in the atmosphere is called Humidity.
• Actual amount of water vapour present per unit volume of atmosphere is called Absolute humidity.
• Hygrometer is the instrument used to measure atmospheric humidity.
• The ratio between the actual amount of water present in the atmosphere and the total waterholding capacity of atmosphere at that particular temperature and time is referred to as Relative Humidity.
• Relative humidity can be estimated based on the difference in temperature recorded in wet and dry bulb thermometers.
• The atmospheric moisture is visible only when the water vapour condenses to form tiny droplets of water.
• Dew, Frost, Mist and Fog and Cloud are the different forms of Condensation.
• Clouds can be classified based on their form as well as the height at which they are formed.
• Cirrus Cloud, Cumulus Cloud, Nimbus Cloud and Stratus Cloud are the types of Clouds.
• As the size of water droplets grows beyond the limit of resistance against gravity, water droplets will be released from the clouds and may fall on earth in various forms. This is termed as precipitation.
• Rainfall, snowfall fall and hailstones are the different forms of precipitation.
• Orographic rain, Convectional rain and Cyclonic rain are the types of rainfall.

WEATHER AND CLIMATE

• The atmospheric conditions of any place depend on the factors such as temperature, pressure, wind and humidity. They in turn, are influenced by the amount of sunlight available there. Hence these are called elements of weather.
• Atmospheric conditions such as temperature, pressure, wind, humidity and precipitation for a shorter period of time are termed as Weather.
• The average weather condition experienced for a longer period over a larger area is termed as the Climate.

The climate of a place is determined by considering the weather conditions of about 35 to 40 years. The climatic conditions of any place is detrimental to the diverse flora and fauna as well as human life of the place. The influence of climatic elements is evident not only in the food habits, dressing, settlement and occupation but also in the physical and mental conditions and in the colour and race of mankind as well. Agricultural practices world over mainly correspond to the climatic conditions. Weather has always been an influential factor right from the early marine voyages which revolutionised the world history, to the modern transport and communication systems.

Indian Meteorological Department (IMD)
Indian Meteorological Department is the agency functioning under the Ministry of Earth Sciences, Government of India. This is the principal agency responsible for the weather observations, weather forecast etc. in the country. Delhi is the headquarters of IMD. Hundreds of observation stations are functioning at various places in India as well as in Antarctica.

ATMOSPHERIC TEMPERATURE

• Sun is the sole source of energy for the earth.
• Energy is produced in the sun by nuclear fusion.

Massive amount of energy continuously produced in the sun through nuclear fusion is emitted in the form of short waves. Only a small amount of energy radiated from the sun reaches the earth’s surface (approximately one part of 200 million). The amount of sun’s rays reaching the earth’s surface is called Insolation. A part of insolation coming towards the earth gets reflected or absorbed by the atmospheric particles such as clouds and dust particles. As the incoming solar radiation is in the form of short waves, it does not heat the atmosphere considerably. The earth’s surface gets heated by insolation. Then the heat is transferred to the atmosphere through various processes from the earth’s surface.

Nuclear Fusion

Nuclear fusion is the reaction in which two or more atomic nuclei collide and merge together to form a larger atom. This process is common in the case of elements with lower atomic number. Massive amount of energy is generated through this process. In all the stars including the sun, energy is continuously generated through nuclear fusion. It is estimated that 600 million tonnes of Hydrogen is being converted to Helium every second in the sun through this process.

Processes of heat transfer
Conduction, convection, advection and radiation are the major processes of heat transfer.

• Conduction : Heat is transferred to the lower part of the atmosphere which is directly in contact with the surface of the earth.
• Convection: As the heated air expands and rises up, heat is transferred to higher reaches of the atmosphere.
• Advection: Heat is transferred horizontally through wind.
• Radiation: Emission of energy in the form of long waves after the earth’s surface gets heated up.

Short waves and Long waves
Energy is radiated in the form of short waves from hotter objects. Due to high frequency, the short waves traverse through the atmosphere without obstruction. Objects with relatively less heat radiate energy in the form of long waves. Due to low frequency, long waves will be absorbed or reflected by the atmospheric particles.

Green House Effect: The re-radiation of energy in the form of long waves from the earth’s surface is called Terrestrial radiation. The absorption of terrestrial radiation by the atmospheric gases such as carbon dioxide heats up the atmosphere. This phenomenon is termed as Green House Effect. Almost entire energy reaching the earth as insolation is radiated back every day Thus the surface temperature of the earth remains balanced without becoming extremely hot or cold. This process of heat balancing is called the Heat Budget of the Earth.

Heat Budget
Consider the total amount of solar energy reaching the top of the atmosphere of the earth as 100 units. Out of this, 35 units will be reflected back and 14 units will be absorbed by the atmospheric particles. The total amount of energy reaching the surface of the earth is estimated as 51 units. Out of this, 34 units will be transferred to the atmosphere through the processes of heat transfer such as conduction and convection. By re-radiating 17 units of energy directly from the earth’s surface and 48 units from the atmosphere, the entire energy received bv the earth and its atmosnhere nets sent back.

Maximum and Minimum Temperature
The surface temperature of the earth gradually increases by the flow of insolation since the sun rise and attains the maximum by the noon. As the atmosphere is heated through various processes of heat transfer, it takes more time for the atmosphere to get heated up than the time taken for the earth’s surface.

Thus the temperature recorded at 2pm is considered as the maximum temperature of the day by the meteorologists. The surface temperature of the earth gradually decreases in the afternoon due to the decrease in intensity of insolation as well as the simultaneous terrestrial radiation. The earth’s surface as well as the atmosphere get cooled by more energy loss through terrestrial radiation during night. Thus the temperature recorded just before the sun rise is considered as the minimum temperature of the day.

Maximum – Minimum Thermometer
Atmospheric temperature is measured using an instrument called Thermometer. Maximum – Minimum thermometer is a special type of instrument made by connecting two ordinary thermometers using a U-shaped glass tube. The Maximum temperature and the Minimum temperature of a day can be read out from the recordings of a Maximum-Minimum thermometer.

By making use of the maximum temperature and the minimum temperature, diurnal range of temperature and daily mean temperature can be calculated.

• Diurnal range of temperature is the difference between the maximum temperature and the minimum temperature of a day.
  Diurnal Range = Maximum temperature – Minimum temperature
• The average temperature of a day is called as Daily mean temperature.
  Daily mean temperature = \(\frac{\text { Maximum temperature }+ \text { Minimum temperature }}{2}\)

Data regarding the temperature are being utilized for climatic studies and further analysis. Plotting the temperature recorded at specific places, smooth curved lines are drawn connecting the places having equal temperature. These imaginary lines are called Isotherms. Isotherm maps are very useful for analysing temperature distribution. World distribution of temperature using isotherms:

• Temperature gradually decreases while moving away from the equator.
• The isotherms show a noticeable bend along land-sea confluences.
• Compared to the Northern Hemisphere, Isotherms are more or less parallel to the latitudes in the Southern Hemisphere.
• There is spatial and temporal variation in the temperature experienced on earth.
• Degree Celsius and Degree Fahrenheit are the common units for recording temperature.
• In Fahrenheit the melting point of water is 32° and the boiling point is 212°.
• This is equivalent to 0° Celsius and 100° Celsius respectively.
  °F = °C x \(\frac{9}{5}\) + 32 °C = (°F – 32) \(\frac{5}{9}\)

Heat and Temperature

• The total energy of an object due to molecular movement is termed as Heat. It is measured in Joule.
• Degree of hotness of an object is its temperature. Temperature is recorded in units such as Degree Celsius, Degree Fahrenheit and Kelvin.

Thermal Equator
Imaginary line connecting places with highest mean annual temperature along every longitude is termed as Thermal Equator.

FACTORS INFLUENCING THE DISTRIBUTION OF TEMPERATURE
Latitude

• Very high temperature is experienced along the equatorial regions where the incidence of sun’s rays is almost vertical.
• Owing to the spherical shape of the earth, the incidence of sun’s rays are more inclined away from the equator towards the poles.
• Thus the temperature gradually decreases towards both the poles. On the basis of this, different temperature zones may be formed.

Altitude: Atmospheric temperature gradually decreases with increase in altitude. The phenomenon of gradual decrease in temperature at the rate of 6.4° Celsius per kilometre of altitude is termed as Normal Lapse Rate.

Differential Heating of Land and Sea: Compared to sea, land gets heated and cooled at a faster rate. Thus the land areas experience higher summer temperature and lower winter temperature, when compared to sea.

Distance from the Sea: The winds blowing from land to sea and vice versa help to moderate the temperature experienced along coastal areas. Away from the sea, the maritime influence gradually decreases to cause very high day temperature and low night temperature.

Ocean Currents: The temperature along the coastal regions is raised or lowered by the warm currents and cold currents respectively as they pass by. For example, the warm current called North Atlantic Current gives relief for the Western European countries from severe cold.

On the other hand, the places situated along the North Eastern Canada, which are also in the same latitude, experience severe cold for months due to the influence of Labrador cold current.

Relief: Availability of sunlight differs from one place to another in accordance with the relief. Due to this difference, the mountain slopes facing the sun experience higher temperature and opposite slopes experience lower temperature.
Eg: In the given figure mountain slopes marked as B gets more sunlight.

ATMOSPHERIC PRESSURE
Like any other matter, air also has weight. The weight exerted by the atmospheric air over the earth’s surface is termed as Atmospheric Pressure. Barometer is the instrument used to measure atmospheric pressure. Barometers are of different types such as Mercury Barometer and Aneroid Barometer. In Mercury Barometer, the average pressure on the earth’s surface is recorded as 76 cm. Atmospheric pressure is usually recorded in units millibars (mb) or hectopascal (hpa). The average atmospheric pressure experienced on the earth’s surface is estimated as 1013.2mb or hpa. Following are the factors affecting atmospheric pressure.

• Temperature: Atmospheric air expands on getting heated, and rises up. Thus low pressure regions are formed. This rising air gradually cools, contracts and subsides to form high pressure regions.
• Altitude: As the density of atmospheric gases decreases with increase in altitude, atmospheric pressure gradually decreases. The vertical variation of atmospheric pressure is at the rate of about, lmb per 10 metres.
• Humidity: As the humidity increases, the water molecules displace the heavier gases in the atmosphere like nitrogen and oxygen. The atmospheric pressure becomes low, as humid air is lighter than dry air.

The air movements right from light breezes to violent gales are the results of variations in atmospheric pressure. Thus, thorough analysis regarding the spatial distribution of atmospheric pressure is essential for meteorological purposes.

• Smooth curved lines are drawn on maps to connect places having equal atmospheric pressure. These imaginary-lines are called Isobars.
• The given map showing the world distribution of atmospheric pressure using isobars.The symbol ‘H’
  represents High Pressure Centres and ‘L’ Low Pressure Centres.

Global Pressure Belts: Temperature is inversely proportional to pressure. Thus the lowest atmospheric pressure might be experienced in the equatorial region and the highest might be in the polar regions. The pressure should therefore increase from the equator towards the poles. But actually this is not the case. Distinct pressure conditions prevail at certain specific zones due to the influence of the rotation of the earth.

• Different pressure belts are formed along certain specific latitudinal zones. These are called Global Pressure Belts.

• The expansion and rising up of air due to high temperature prevailing in the equatorial region is the cause for the formation of Equatorial Low Pressure Belt.
• This zone of vertical air currents is devoid of winds. Being the windless zone, this pressure belt is called Doldrum.
• Atmospheric conditions along the poles are just opposite to that in equatorial region. Polar High Pressure Belts are formed as a result of the contraction and subsidence of cold air.
• The rising warm air along the equatorial region moves polewards as upper air winds which gradually cool and subside at about 30° North and 30° South latitudes. This results in the formation of Sub Tropical High Pressure Belts.
• At about 60° North and 60° South latitudes, normally high pressure zones should be formed due to lower temperature conditions. But owing to the continuous throwing up of air along these regions caused by the influence of the rotation of the earth Sub Polar Low Pressure Belts are formed.
• As the temperature conditions vary with the apparent movement of the sun, the global pressure belts are subjected to relative shifts.
• Global pressure belts may shift to about 5° to 10° northwards during summer season and shift southward during winter season. This shifting of global pressure belts has decisive influence on global climate.
  The pressure differences in the atmosphere are largely noticeable through air movements. There are two types of air movements in the atmosphere.
• Air Currents: Air Currents are the vertical movements of air.
• Winds: Winds are the horizontal movements of air from high pressure areas to low pressure areas.

WINDS
Winds are of different types, varying from light breezes to devastating gales. Winds are named according to the direction from which they blow. For example, the winds blowing from the south west are termed as south west winds and the winds blowing from the sea towards the land are termed as sea breezes.

• One of the major factors influencing the direction of winds is the Coriolis Force.
• Owing to” the Coriolis effect, the winds will deflect towards the right of its direction in the Northern

Hemisphere and towards the left of its direction in the Southern Hemisphere.

The speed and intensity of winds are influenced mainly by two factors.
a) Pressure gradient force
b) Frictional force

a) Pressure gradient is the change in pressure over a horizontal distance. If there is considerable change in pressure between nearby places, it indicates high pressure gradient. If there is no considerable difference of pressure over horizontal distance, pressure gradient is said to be low. At places where there is high pressure gradient, winds will be strong.

b) The friction caused by hills, mountains, forests and man¬made structures will obstruct the free flow of winds.

Anemometer and Wind Vane

• Anemometer is the instrument used to measure the speed of wind. The distance travelled by wind per hour can be estimated using this instrument.
• Wind Vane is the instrument which indicates the direction of wind.

TYPES OF WINDS

a) Permanent Winds
The winds blowing constantly over a particular direction throughout the year are called Permanent winds. These winds are also known as prevailing winds and planetary winds. These winds blow between global pressure belts. Trade winds, Westerlies and Polar winds are the major permanent winds.

ITCZ
The equatorial low pressure region where the trade winds from the Northern Hemisphere and the Southern Hemisphere converge is known as Inter Tropical Convergence Zone (ITCZ). ITCZ shifts with the apparent movement of the sun.

b) Periodic Winds: Winds subjected to the periodic reversal of their direction are termed as Periodic winds. Diurnal winds such as the land breezes, sea breezes, mountain breezes and valley breezes as well as the monsoon winds which repeat on summer and winter are periodic winds.

Land Breezes and Sea Breezes
The air in contact with the land also gets heated up and ascends as the land heats up quickly during the daytime. This leads to the formation of low pressure over the land which causes the comparatively cooler air to blow from the sea. This is known as sea breeze.

As the land cools faster than the sea during the night it would be high pressure over the land and low pressure over the sea. This results in the movement of air from the land to sea. This is the land breeze.

Mountain Breezes and Valley Breezes
During night, air along the mountain slopes cools, contracts and moves down slope. These winds are called mountain breezes. During day time, the heating by sunlight and rising up of air along the mountain slopes make the wind to blow up slope from the valley. These winds are called valley breezes.

Monsoon Winds
The term ‘monsoon’ implies the seasonal reversal in the wind pattern.
During summer the South Asian land masses, especially the Indian Sub Continent, gets heated up intensely and severe low pressure develops. Wind blows towards the land mass from the Indian Ocean where comparatively high pressure prevails. These winds blowing as South West winds due to Coriolis effect causes widespread rainfall on entering the land. This is Southwest monsoon.

During winter, as the northern land masses get severely cooled, high pressure develops over North India. This causes the winds to blow continuously from the land towards the Indian Ocean as north east winds. These winds.

c) Local Winds: Local winds are winds formed as a result of local differences in temperature and pressure in different parts of the world. Most of the local winds are periodic in nature. These winds are known by local regional names. Details regarding a few such local winds:

Local Winds	Region	Characteristics
Loo	North Indian Plains	Hot wind
Chinook	Slopes of Rocky Mountains in North America	Dry hot wind
Foehn	Slopes of Alps Mountain in Europe	Dry hot wind
Harmattan	Sahara Desert in Africa	Relief to intense heat

d) Variable Winds: Winds of short duration, of which the intensity or direction cannot be predicted are called variable winds. Cyclones and Anticyclones belong to this category.

Cyclones

• Cyclones are low pressure systems towards which winds whirl from the surroundings.
Even if the cyclones developed over the tropical region are comparatively lesser in diameter, they are devastative than temperate cyclones. Tropical cyclones originate over tropical oceans. The tropical cyclones moving in northwest direction over the oceans, get dissipated on hitting the lands. Different temperature conditions prevailing on land and also the friction causes the dissipation of cyclones on entering land. The tropical cyclones cause intense rainfall and strong whirlwinds along the coasts. They are known by different names in different parts of the world such as Hurricanes, Typhoons, Willy Willies, Tornadoes etc. Temperate cyclones are formed in temperate regions where warm and cold air masses meet. Even if the temperate cyclones are larger in diameter, they are less devastative. Unlike the tropical cyclones, these low-pressure systems can move over land also. The direction of flow of air into the cyclones are anticlockwise in the Northern Hemisphere and southern Hemisphere clockwise in the Southern Hemisphere.

Anticyclones

• Anticyclones are high pressure system from which winds whirl outwards. Generally anticyclones do not cause atmospheric disturbances.
• The direction of flow of winds from anticyclones is clockwise in the Northern Hemisphere and anticlockwise in the Southern Hemisphere.

HUMIDITY

• Another weather element caused by solar energy is the atmospheric humidity.
• The invisible water content in the atmosphere is called Humidity.

water rises as water vapour on heating. As a result of heating by sunlight water from different sources on the earth’s surface turns to water vapour and reaches the atmosphere in different quantities.Water vapour remains invisible in the atmosphere.

• Actual amount of water vapour present per unit volume of atmosphere is called Absolute humidity.
• Hygrometer is the instrument used to measure atmospheric humidity.
  Atmospheric humidity varies from place to place depending on the temperature and availability of water. There is a limit to the amount of water vapour that the atmosphere can hold at a particular temperature.
• The ratio between the actual amount of water present in the atmosphere and the total waterholding capacity of atmosphere at that particular temperature and time is referred to as Relative Humidity. It is expressed in percentage.
• Relative humidity can be estimated based on the difference in temperature recorded in wet and dry bulb thermometers.
  Relative Humidity = \(\frac{\text { Absolute Humidity }}{\text { Total water holding capacity of the atmosphere }}\) × 100

The state at which the atmosphere is fully saturated with moistur/water vapour is known as saturation level and the temperature at which this level is attained is termed as saturation point. When the atmosphere is fully saturated with water vapour, condensation begins.

Condensation
The atmospheric moisture is visible only when the water vapour condenses to form tiny droplets of water.
Different forms of Condensation:
a) Dew: During the night, as the earth’s surface cools down, the atmosphere close to the earth’s surface also cools. The water vapour condenses to form tiny droplets of water which may cling on to the grass tips, leaf blades as well as other cold surfaces.

b) Frost: Whenever the atmospheric temperature falls below 0° Celsius, especially during nights, tiny crystals of ice are formed instead of dew.

c) Mist and Fog: When the atmosphere gets cooled, the water vapour condenses to form tiny droplets of water and remains suspended in the lower atmosphere. Fog or mist is formed as a result of condensation of water vapour around tiny dust particles in the lower atmosphere. Fog and mist can be distinguished based on the range of visibility through them.

d) Clouds: Clouds are formed as a result of condensation around the tiny dust particles in the atmosphere. The water droplets thus formed are less than 0.001 cm in diameter. This is why, they remain suspended in the atmosphere.

Clouds can be classified based on their form as well as the height at which they are formed.

• Thin, delicate, feather-like clouds formed at very high altitudes are called Cirrus clouds.
• Thick-layered clouds, usually formed in the lower atmosphere, are called Stratus clouds.
• Cotton wool-like clouds formed as a result of intense convection currents, are called Cumulus clouds. These clouds have great vertical development.
• Dark, rain-bearing clouds, formed in the lower part of the atmosphere, are called Nimbus clouds. The dark colour is due to the thick concentration of water droplets which does not allow light to penetrate through them.
• These clouds are not usually seen independently. Mostly we see the combinations of different types of clouds. Such clouds are called as cirro stratus, strato cumulus, cumulo nimbus, nimbo stratus etc.

Precipitation
As a result of continuous condensation, the size of water droplets within the clouds gradually increases. As the size of water droplets grows beyond the limit of resistance against gravity, water droplets will be released from the clouds and may fall on earth in various forms. This is termed as precipitation. Rainfall, snow fall and hailstones are the different forms of precipitation.

• Rainfall is the common and familiar manifestation of precipitation which is in the form of water droplets.
• Temperature falls below 0° Celsius in cold climatic regions as well as in temperate regions during winter. In such places, precipitation occurs in the form of tiny crystals of ice. This form of precipitation is called snowfall.
• The water droplets released from the clouds are subjected to repeated condensation at different levels of atmosphere. It reaches the earth in the form layered ice pellets. These are termed as hailstones.

Rainfall
Rainfall is the most familiar form of precipitation.

Types of Rainfall
a) Orographic rainfall or Relief rainfall.

Moisture-laden winds from the sea enter the land and will be raised along the mountain slopes. This leads to condensation and formation of rain clouds along the windward slopes of mountains. Rainfall occurring in this manner is called Orographic rainfall or Relief rainfall.

While the windward slopes of mountains get plenty of rainfall, the descending dry air makes the leeward side rainless. Such regions are called Rain Shadow Regions.

b) Convectional Rainfall

Rainfall occurs in the afternoon during summer season due to the convection process.Rainfall occuring in this mamier are called Convectional Rainfall. As the convectional rainfall commonly occurs during afternoons, it is also called 4 O’Clock rains.

c) Cyclonic Rainfall

In cyclonic systems where warm and cold air meet, the warm air will be raised up to cause condensation and rainfall. This type of rainfall is called Cyclonic Rainfall.
As the boundary lines between warm and cold air masses are known as fronts, this type of rainfall are also called Frontal Rainfall.

Torrential rain and Cloud burst
Intense rainfall occurring at certain specific areas for a shorter duration is refereed to as torrential rain. This may lead to flash floods and landslides. If the amount of rainfall exceeds 10 cm per hour, it is considered as Cloud burst. It is most common in mountainous regions. Meteorologists recognised that the landslides that occurred in Kavalappara and Puthumala in Kerala during 2019 were the result of torrential rain following cloud burst. Experts perceive the landslides of Mundakkai and Chooralmala in 2024 to be the result of cloud burst.

Question 29.
Why pepper is important to Europeans?
Answer:
Europeans relied on spices, particularly pepper, to preserve food and for medicinal purposes. These spices were traditionally obtained through trade routes passing via Constantinople. However, after the closure of this route, Europeans were compelled to explore and establish a sea route to Asia to secure access to these valuable commodities.

Question 30.
Write the geographical location of the Atlantic Islands and its importance.
Answer:
The Atlantic Islands are located to the west of Africa in the Atlantic Ocean. Notable among them are Madeira, Azores, Canary and Cape Verde. These islands served as agricultural lands and strategic port centres. The Portuguese, who initially controlled many of these islands, used them as key bases for their operations in Africa and as stopover points for ships travelling to Asia to restock food and water. Later, the Canary Islands became a colony of Spain.

Question 31.
How New World was transformed as America.
Answer:
Spain was another country that took part in geographical expeditions. They, too, had a long coast and seafaring heritage just like the Portuguese. They received the patronage of King Ferdinand and Isabella, the rulers of Spain. With the financial aid of Spain in 1492, Christopher Columbus, an Italian navigator, reached the Bahamas Islands located in the southeastern region Vasco da Gama of North America. This journey led to the discovery of a previously unknown continent for Europeans. The event paved the way for the invasion and exploitation of the region by Europeans, which came to be known as the “New World.” Eventually, this region was named America.

• Competition between European countries for colonies
• Formation of military alliances
• Formation of aggressive nationalist movements -Imperialist Crisis
• The conflicts between the imperialist powers and the competition between the European countries for colonial gains led to the formation of military alliances
• Formation of Aggressive nationalism
• Aggressive nationalists considered their own nations as supreme and justified whatever the actions of their nations.

Question 36.
Finance capitalism works with the aim of making huge profits. Justify.
Answer:
FinanciaLexchanges are more important at this stage than industrial production and population welfare. Banks, stock market and investment institutions play a crucial role in this economy. This system allows for the accumulation of more wealth without any production or technological change. Finance capitalism allows big corporates to exert influence beyond military’ power and war. Such companies invest in different countries and make profits. Finance Capitalism works with the aim of making huge profits. Common people and those involved in traditional occupations continued to suffer the consequences.

They lose the resources they could have used freely and are controlled by capitalists. Uncontrolled exploitation of resources also leads to environmental problems. New technologies and related changes in society have led to the emergence of these economic changes. Capitalism developed through several stages over five centuries. It highlights the role of economic factors and systems in determining the course of history. Along with this, this period also witnessed the collapse of human values before capitalist interests.

Question 37.
Define the following terms.
a. UN Organisation
b. League of Nations
c. Bullion coin
d. Fascism
e. Agrarian revolution
Answer:
a. UN Organisation: After the Second World War, the United Nations Organisation was formed with the aim of ensuring global peace and security. It was established on October 24, 1945.

b. League of Nations: Woodrow Wilson, the American President, proposed the idea of forming an international organisation to maintain world peace and ensure freedom for all nations. Based on this proposal, the League of Nations was established on January 10,1920, to restore global peace and security.

c. Bullion Coin: The silver and gold collected as wealth were known as Bullion. The value and amount of the metals in the coins were considered for the transactions. E.g., the value of the gold in a gold coin would be considered as its value in transaction.

d. Fascism: The term “Fascism” is derived from the Latin word ’fasces’, which refers to ‘a bundle of rods and an Axe’ symbolising authority and power, a representation of the rule of Roman emperors.

e. The term ‘Agrarian Revolution’ is used to refer to the series of changes that took place in England’s
agricultural sector in the 17th century. Major changes associated with the Agrarian Revolution:

involved in trade before these explorations became very wealthy and were referred to as merchant capitalists. This economic system was known as Merchant Capitalism. In this system, merchants supplied raw materials to artisans living in rural areas. The artisans manufactured goods in cottage-based production. After compensating the artisans for their labour, the merchants sold the finished products and made profits. These merchants acted as intermediaries between producers and consumers. England started industries using the wealth gained through colonisation. Those who invested their wealth in this way became the owners of industries and made huge profits. With this, merchant capitalism gave way to industrial capitalism.

Question 40.
What are the major changes that took place in the Industrial Revolution?
Answer:

• production was mechanised
• advancement in metallurgy leading to the production of better tools
• steam was used as a source of energy
• transport facilities developed
• production shifted from cottages to factories

Question 41.
Write a note on First world war
Hints:
a. Imperialist Rivalry
b. Extreme Nationalism
Answer:
a. The new imperialist nations could expand their influence only by capturing territories controlled by the older imperialist powers. Germany’s unprecedented progress in economic and industrial sectors caused concern for France and England. With much of Asia and Africa already under British and French control, Germany turned its focus towards regions under the Ottoman Empire. To achieve this, they planned the construction of the Berlin-Baghdad railway line. This project alarmed England, France, and Russia, as they feared it could threaten the security of their territories. Consequently, tensions and hostilities began to escalate among these nations.

b. Extreme nationalism refers to an intense and emotional devotion to one’s country, often involving its excessive glorification. This concept is often related to racism. Many nations argued that regions inhabited by a particular race rightfully belong to that race alone. Such arguments were used by many nations to justify territorial expansion and conquest. In countries like Germany and Serbia, extreme nationalism grew in alarming proportions. Movements such as Pan-Slavism and Pan-Germanism serve as examples of organisations promoting such extreme nationalist ideologies.

Question 42.
Write a note on the formation of Military alliances with respect to the aftermath of first world war.
Answer:

• The competition for colonies and the rise of extreme nationalism created fear and mistrust among European nations. This atmosphere of suspicion led to the formation of military alliances.
• Two military alliances: Triple Alliance, Triple Entente.
• Sarajevo, the capital of Bosnia, was the site of a significant event that further fuelled tensions.

Conflicts arose across various parts of the world between countries belonging to the two major alliances. These conflicts often stemmed from attempts to seize colonies held by rival nations. The situation escalated as allied nations joined forces with their respective allies, intensifying the clashes.

Sarajevo, the capital of Bosnia, was the site of a significant event that further fuelled tensions. Archduke Franz Ferdinand, the Crown Prince of Austria-Hungary, was assassinated in Sarajevo, where former French president Mitterrand visited. The assassin, Gavrilo Princip, was a Serbian nationalist. Due to the existing conflict between Serbia and Austria-Hungary, Austria accused Serbia of orchestrating the assassination. This led Austria-Hungary to declare war against on Serbia on July 28, 1914. As allied nations aligned themselves with their respective sides, the conflict expanded into a World War.

Aftermath of the First World War:

• Millions of soldiers and civilians lost their lives
• Industrial and agricultural sectors were devastated
• marked the beginning of the decline of European global domination
• Freedom movements in Asia and Africa gained momentum.
• Formation of the League of Nations
• Italy, Germany, and Spain transitioned to totalitarian regimes

Question 43.
Differentiate between the policies of Italy and Germany.
Answer:

ITALY

GERMANY

• The ideology was known as Fascism in Italy. • Founder: Benito Mussolini • In 1922, Mussolini organised the March on Rome, using threats and terror to seize power. • Rose to power following the march. • Formed a militia called the Blackshirts. • Banned all non-Fascist political parties. • Enmity towards socialists, labour, and peasant organisations.

• The ideology was referred to as Nazism in Germany. • Founder: Adolf Hitler • In 1923, Hitler led a march to Berlin and was subsequently imprisoned. • Initiated efforts to secure power through elections. • Established a militia known as the Brownshirts. • In the 1933 elections, he failed to win a majority but came to power through manipulations. • Initiated efforts to eliminate Communists, Socialists, Democrats, and Jews.• Formed the Gestapo (secret police) to gather intelligence and suppress opposition. • Hitler’s aggression led to World War II.

Question 44.
Write the background of second world war.
OR
What are the causes and consequences of second world war (MODEL 2023)
Hints:
a. Treaty of Versailles
b. The failure of league of nations
c. Formation of military alliances
d. Policy of appeasement
Answer:
a. Treaty of Versailles
The Treaty of Versailles was a peace treaty that Germany signed with the Allies after World War I. Its provisions sowed the seeds of World War II. Under this treaty, Germany lost its colonies and territories it held. Germany was disarmed and huge war reparations were imposed on Germany. In short, World War II was a German revolt against the Treaty of Versailles and its architects.

b. The failure of league of nations
The League of Nations formed after World War I was unable to resolve disputes or enforce international disarmament. The league failed to act when Japan, Italy, and Germany launched offensives.

c. Formation of military alliances
Imperialist rivalry led to the formation of the following military alliances.

Later Soviet Union and USA became part of the allied powers

Munich agreement
Hitler laid claim to the Sudetenland, the most industrialised region of Czechoslovakia. Hitler’s argument was based on the large German population living in Czechoslovakia. Instead of resisting Hitler’s argument, France and Britain ceded the Sudetenland to Germany in a treaty signed in Munich, Germany in 1938. This is called the Munich Agreement. This treaty was not ratified by Czechoslovakia. The Soviet Union, which supported them, was not invited to the talks.

d. Policy of appeasement

• The Soviet Union, which came into being after the Russian Revolution, spread socialist ideas around the world.
• The Munich Agreement is a prime example of Western appeasement.

The Soviet Union, which came into being after the Russian Revolution, spread socialist ideas around the world. This was a threat to other western capitalist countries. For this reason, they saw the Soviet Union as their enemy. They saw fascist aggression as a means of countering the spread of socialist ideas. The Munich Agreement is a prime example of Western appeasement. These appeasement policies gave Hitler confidence and he continued his offensives aggressively. World War II begins with Germany’s invasion of Poland on September 1,1939. Results of the war:

• Millions lost their lives
• Famines and epidemics spread throughout the world
• The European economy collapsed
• Colonisation and imperialism faced setbacks
• Europe’s hegemony came to an end
• The United Nations Organization was formed
• Totalitarianism ended in Italy and Germany
• Colonies in Asia and Africa gained independence
• The United States and the Soviet Union emerged as global powers

United Nations Organisation
After the Second World War, the United Nations Organisation was formed with the aim of ensuring global peace and security. It was established on October 24,1945.

Causes of the war

• The background of the Second World War took place from 1939 to 1945.
• World War II begins with Germany’s invasion of Poland on September 1, 1939.

SCERT Class 10 Social Science Geography Chapter 2 Climatic Regions and Climate Change Notes Question Answer Kerala Syllabus

Class 10 Geography Chapter 2 Notes Kerala Syllabus Climatic Regions and Climate Change

Question 1.
Didn’t you know that the Indian subcontinent, of which our country is a part, receives rain mostly during the monsoon season?
Answer:
The Indian subcontinent, comprising countries like India, Pakistan, Bangladesh, Nepal, Bhutan, and SriLanka, gets most of its annual rainfall during the monsoon season, which typically spans from June to September. This is due to the Southwest Monsoon, a seasonal wind that brings moisture-laden air from the Indian Ocean. As this air moves inland and meets the Western Ghats, the Himalayas, and other elevated terrain, it rises, cools, and releases heavy rainfall. In fact, in many parts of India, more than 70% – 80% of the yearly rainfall happens during this period. It’s a huge part of life in the region; agriculture, water supply, and even the economy relies heavily on a good monsoon.

Question 2.
Is monsoon climate experienced only in the Indian subcontinent?
Answer:
No, the monsoon climate is not only in the Indian subcontinent but also occurs in Southeast Asia, East Asia, West Africa, Northern Australia, and parts of South America.

Question 3.
Some other regions of the world also experience similar climatic conditions. Observe the map given below and the atlas and list the regions experiencing a monsoon climate.

Answer:
Based on the map provided, the regions of the world that experience a monsoon climate include:

1. South Asia: India, Bangladesh, Sri Lanka, Nepal, and surrounding areas.
2. Southeast Asia: Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, Indonesia, and the Philippines.
3. East Asia: Southern parts of China and parts of Japan.
4. West Africa: Coastal regions including Nigeria, Ghana, and Ivory Coast.
5. East Africa: Areas like Tanzania and Mozambique.
6. Northern Australia
7. Northeastern South America: Northern Brazil and nearby regions.
8. Parts of Central America and the Caribbean: Some coastal zones in southern Mexico and surrounding areas.

Question 4.
Does convectional rainfall occur in the monsoon climatic region?
Answer:
Yes, convectional rainfall occurs in monsoon climatic regions, especially during the hot summer months. In monsoon regions, convectional rainfall happens when the land heats up due to the sun, causing the air above it to become warm and rise. As this warm, moist air rises, it cools and condenses, forming clouds and resulting in heavy, short-duration rainfall, often with thunder and lightning. This type of rain is common in the afternoons and contributes to the overall rainfall during the monsoon season. So, while the majority of rainfall in these regions comes from monsoon winds, convectional rainfall also plays an important role, especially at the beginning of the rainy season.

Question 5.
With the help of ICT, collect images of plants and animals found in monsoon forests and create a digital album of the same. Caption them.
Answer:
(Hints)

Question 6.
Why are crops like jute, sugarcane, rice, etc are called tropical crops?
Answer:
These crops are called tropical crops because they are grown mainly in tropical regions, which lie between the Tropic of Cancer and the Tropic of Capricorn. These areas have:

• Warm temperatures throughout the year
• High humidity
• Heavy rainfall, especially during the monsoon season

Such climatic conditions are ideal for the growth of crops like rice, sugarcane, cotton, tea, coffee, and bananas, which thrive in hot and moist environments typical of the tropics.

Europe	Yes
Asia	Yes
Africa	No
South America	No
Australia	No

Question 16.
Lumbering is more industrialised in the Taiga region than in the equatorial region. Why?
Answer:
Lumbering is more industrialised in the Taiga region than in the equatorial region because the trees in the Taiga are tall, straight, and grow close together, making them easy to cut with machines. The cold climate and frozen ground allow machines to work better. Also, Taiga regions are in developed countries like Canada and Russia, which have good roads and modern technology. On the other hand, equatorial forests are very thick, hot, and wet, with uneven trees and poor transport, which makes cutting and moving the wood difficult.

Earth’s orbital changes	Transportation (vehicles, airplanes)
–	Agriculture (especially livestock)
–	Use of aerosols and CFCs

Question 19.
How does climate change affect human life?
Answer:
Climate change affects human life in many serious ways. It causes more extreme weather events like heavy rainfall, floods, droughts, storms, and heatwaves. These events can destroy homes, farms, and roads, making it hard for people to live and work. Rising temperatures can lead to health issues such as heatstroke, breathing problems, and the spread of diseases like malaria and dengue. Sea levels are rising because of melting ice, which can flood coastal cities and force people to leave their homes. Climate change also makes farming harder by affecting rainfall and soil, which can lead to food shortages and higher prices. Overall, climate change is a big challenge that affects our health, safety, and daily life.

Question 20.

• Forests may dry out, leading to loss of biodiversity.

Tropical Deserts:

• Hotter temperatures and longer dry periods.
• Water scarcity becomes worse.

Monsoon Regions:

• Irregular and unpredictable rainfall.
• Floods and droughts affect farming and water supply.

Temperate Regions:

• Warmer winters and hotter summers.
• Increased risk of wildfires and storms.

Taiga Region:

• Melting snow and frozen ground (permafrost).
• Forests may catch fire more easily.

Tundra Region:

• Rapid warming leads to melting of ice and snow.
• Animal habitats are disturbed and some species may go extinct.

Polar Regions:

• Ice sheets and glaciers are melting quickly.
• Sea levels are rising, and wildlife like polar bears are at risk.

INTRODUCTION

This chapter “Climatic Regions and Climate Change” provides an overview of the various climatic zones found around the world and how they affect life and the environment. It begins by explaining the concept of climatic regions, which are classified based on temperature, rainfall, and seasonal patterns. Key regions discussed include hot deserts, known for their extreme heat and dry conditions; the Mediterranean region, which has hot, dry summers and mild, wet winters; and temperate grasslands, characterised by moderate rainfall and wide temperature ranges, making them ideal for farming. The chapter also covers cold regions, such as tundras and polar areas, where long, harsh winters and limited vegetation dominate. Lastly, it addresses the pressing issue of climatic change, focusing on global warming, its human and natural causes, and its significant impact on weather patterns, ecosystems, and human societies.

Climatic Region

• Our Earth is enriched with diverse climates.
• Some places experience severe cold and snowfall, whereas it will be extremely hot and arid elsewhere. There are also areas with moderate temperature and humidity.
• Based on the fluctuations in elements of weather such as temperature and precipitation, the world can be divided into different climatic regions.
• Major climatic regions of the world are given below:
  • Equatorial climatic region
  • Monsoon climatic region
  • Savanna climatic region
  • Hot deserts
  • Temperate grasslands
  • Mediterranean climatic region
  • Taiga region
  • Tundra region
• A climatic region is an extensive geographical area in which similar climate characteristics are observed.
• Each climatic region has its own unique climate, and flora and fauna develop according to it.
• Equatorial climatic region extends up to 10° North and South of the equator.

Hot deserts

• Hot deserts are regions with very little rainfall.
• Tropical deserts are the hottest regions on earth with an average annual temperature of 30°C.
• The highest recorded temperature in A1 Aziziya in the Sahara Desert is 58° C.
• Annual rainfall in desert areas is generally less than 25 cm, and in some places, it may not rain for several years.

• Agriculture and animal husbandry are the main means of livelihood in deserts.
• Another factor that promotes human life in desert is the presence of economically valuable minerals.

Mediterranean climatic region

• The areas about mediterranean sea is the area of the mediterranean region.
• It is a region that experiences dry summers and humid winters. Temperature of around 20 – 25° C is experienced in summer.
• Highest temperature during winter is 10° C to 16° C.
• Winter rainfall of 30 to 75 cm distinguishes this region from other climatic regions.
• Rains during the winter are beneficial to the winter crops.
• The Mediterranean countries are the world’s leading producers of wine.
• About 70 precent of citrus fruit export comes from the Mediterranean countries.

Temperate grasslands

• The grasslands are located in both the hemispheres at a latitude between 40° and 50° and are known by different names in different regions.
• Though temperate grasslands are found in different parts of the world, their climate characteristics are almost the same.
• Rainfall here ranges from 25 cm to 60 cm Fluctuations in the rainfall availability is reflected in vegetation also.
• The flora and fauna and the life of the people of each region are formed according to the climate characteristics.
• Commercial mechanised grain farming and animal husbandry are increasing day by day in this region.
• Average winter temperature ranges from 2° to 13° C.

Cold region

• Taiga region
  • It is a cold region located between latitudes of 55° and 70° in the Northern Hemisphere.
  • Short summers and long winters are experienced there. Summer temperature is from 15° C to 20° C while winter temperature drops up to -13° C to -25 ° C.
  • This region receives an annual rainfall of 50 cm to 70 cm. In winter, precipitation is in the form of snowfall.
  • Taiga is the Russian word for ‘coniferous trees’.
• Tundra region
  • Tundra region is the extreme cold zone extending from north of the Arctic Circle in Alaska, Canada, Greenland, and the Arctic coasts of Europe and Asia.
  • Here winter temperature ranges from -25°C to -40°C and the summer temperature rises up to 10°C. Precipitation is mainly in the form of snowfall.

Climatic Changes

• UN defines ‘climate change’ as a long-term shift in weather patterns and temperatures that is caused by human activity or natural variability.
• Global sea level is estimated to rise by 0.42 cm per year as a result of climate change.
• Earth’s climate has not always been the same; climate has undergone cyclic changes throughout the Earth’s history.
• Natural climate change resulting from endogenic earth processes cannot be controlled by human efforts.
• Activities such as industrialisation, land use change, and urbanisation are some of the human interventions that lead to climate change.
• Atmospheric temperature, pressure, winds, precipitation and humidity are the elements of climate.
• Climate change can be classified into two categories as natural and anthropogenic.

CLIMATIC REGION

• Our Earth is enriched with diverse climates.
• Some places experience severe cold and snowfall, whereas it will be extremely hot and arid elsewhere. There are also areas with moderate temperature and humidity.
• Based on the fluctuations in elements of weather such as temperature and precipitation, the world can be divided into different climatic regions.
• A climatic region is an extensive geographical area in which similar climate characteristics are observed.
• Each climatic region has its own unique climate, and flora and fauna develop according to it.

Major climatic regions of the world are given below:

• Equatorial climatic region
• Monsoon climatic region
• Savanna climatic region
• Hot deserts
• Temperate grasslands
• Mediterranean climatic region
• Taiga region
• Tundra region

EQUATORIAL CLIMATIC REGION

• This climatic region extends up to 10° North and South of the equator.
• Evergreen forests are abundant in the equatorial climatic region due to high temperatures and high rainfall.

The equatorial climatic region is characterised by high temperatures and high rainfall throughout the year. This climatic region is hotter because sun’s rays fall almost vertically throughout the year. This results in higher air convection and convectional precipitation. These areas receive rainfall every day in the afternoon.

MONSOON CLIMATIC REGION

• Monsoons are the seasonal reversal of wind system.
• These winds blow from sea to land in summer and get reversed from land to sea in winter.
• This region is known as a monsoon climatic region because of the decisive influence of monsoon winds.

Monsoon climate is characterised by long and humid summer and short dry winter. In monsoon climatic regions, diurnal range of temperature is very low in coastal areas and very high in the interiors. Depending on the factors like physiography, direction of wind, and distance from the coast, rainfall distribution also varies in the monsoon regions. Regions with as little as 50 cm of rainfall to areas receiving over 1000 cm of annual rainfall can be found in this region.

• Luxuriant growth of vegetation due to the high temperature and rainfall helps forests in this region to become dense.
• Evergreen and deciduous trees are generally found here.
• Monsoon forests, also known as tropical deciduous forests, have a mixture of different types of trees depending on the amount of rainfall received.

Monsoon region is one of the most densely populated areas in the world. High rainfall and availability of labour keep the monsoon climatic region an important agricultural region. Tropical crops like rice, sugarcane, jute, cotton, tea and coffee, are cultivated here.

• Intensive subsistence agriculture is prevailing in this region.
• In rare areas, shifting cultivation, a primitive subsistence agriculture, also exists.

With the variations in the availability of rainfall, the type, height and diversity of flora also vary. Diversity is evident in fauna also.

SAVANNA CLIMATIC REGION

• Savannas are tropical grasslands found between 10° and 30° latitudes in both the hemispheres.
• Tropical grasslands have hot and humid summers and cool and dry winters.

These grasslands are known by different names in different regions. It is known as Savanna in Africa, Campos in Southern Brazil and Llanos in Venezuela. The annual average temperature here is between 21°.C and 32° C, and it also receives annual rainfall of 25 cm to 125 cm.

Deciduous trees and tall grasses are the dominant vegetation of this region. As we move closer to the deserts, short bushes and thorny forests are seen. The forests and grasslands here provide a favourable habitat for wild animals. Herbivorous animals like giraffes and zebras abound in these grasslands. Carnivorous animals like lion and tiger are also found here.

• Soil found here is relatively fertile, due to low rainfall, ‘dry fanning’ that requires less amount of water, is adopted.
• Animal husbandry and agriculture are the means of livelihood of the people. Population density is generally low in the savanna region. Maasai, an indigenous tribe of the African savanna, leads a pastoral life.
• Cash crops are cultivated extensively in the savanna areas of former European colonies. Cotton cultivation in Sudan and coffee cultivation in Brazil are example.
• The western margins of tropical grasslands, height of the trees gradually decreases with the decrease in rainfall. This is followed by desert vegetation.

HOT DESERTS

• Hot deserts are regions with very little rainfall.
• Tropical deserts are the hottest regions on earth with an average annual temperature of 30°C.
• The highest recorded temperature in A1 Aziziya in the Sahara Desert is 58° C.
• Annual rainfall in desert areas is generally less than 25 cm, and in some places, it may not rain for several years.
• Western margins of continents remain dry throughout the year. This is the main reason for the formation of deserts on the western margins of continents.
• Agriculture and animal husbandry are the main means of livelihood in deserts.

High diurnal range of temperature makes desert climate very difficult. Annual rainfall in desert areas is generally less than 25 cm, and in some places, it may not rain for several years. In the tropical region, hot deserts are located mostly on the western margins of continents. As the trade winds travel across the continents and reach the western margins, the wind loss its moisture and becomes dry. Therefore, the western margins of continents remain dry throughout the year. This is the main reason for the formation of deserts on the western margins of continents. Plants adapted to low rainfall climate such as cactus, shrubs and palms are mostly found here. Oases are formed in places where water sources are found. Oases (plural of oasis) are fertile areas in a desert where water is available. They are like natural “green spots” in the middle of dry, arid surroundings.

• These areas are sparsely populated due to the unfavourable climate and other factors.
• However, there are indigenous tribal communities who have adapted to the adverse conditions in most of the desert regions. The Bushmen of Kalahari Desert are an example for this.

Another factor that promotes human life in desert is the presence of economically valuable minerals. Gold mining in Australia and copper in the Atacama Desert are examples of this. Discovery of petroleum deposits and the starting of oil mining in the Sahara and Arabian deserts have changed the very face of these regions.

MEDITERRANEAN CLIMATIC REGION

• The areas about mediterranean sea is the area of the mediterranean region.
• It is a region that experiences dry summers and humid winters. Temperature of around 20 – 25° C is experienced in summer.
• Highest temperature during winter is 10° C to 16° C.
• Winter rainfall of 30 to 75 cm distinguishes this region from other climatic regions.
• Rains during the winter are beneficial to the winter crops.
• The Mediterranean countries are the world’s leading producers of wine.

Apart from the coasts of Mediterranean Sea, some other regions lying between 30° and 45° latitudes also experience the same climate. All these regions are collectively known as the Mediterranean climatic regions. Westerlies are responsible for winter rainfall in the Mediterranean region. Dense forests are not found due to low rainfall. Tall evergreen trees such as oak and sequoia, evergreen conifers such as pine and fir, and shrubs are found here. Fruits and vegetables are the major produces of this region. Cereals and pulses are also cultivated wherever possible. Agricultural practices developed according to the climate conditions and related activities make the Mediterranean region an area of great economic importance. As in the tropics, in the interior of the subtropical zone, the maritime influence is minimal and treeless grasslands are found. These are the temperate grasslands.

• The Mediterranean countries are the world’s leading producers of wine.
• About 70 precent of citrus fruit export comes from the Mediterranean countries.
• As in the tropics, in the interior of the subtropical zone, the maritime influence is minimal and treeless grasslands are found. These are the temperate grasslands.

TEMPERATE GRASSLANDS

• These grasslands are located in both the hemispheres at a latitude between 40° and 50° and are known by different names in different regions.
• Though temperate grasslands are found in different parts of the world, their climate characteristics are almost the same.
• Rainfall here ranges from 25 cm to 60 cm Fluctuations in the rainfall availability is reflected in vegetation also.
• The flora and fauna and the life of the people of each region are formed according to the climate characteristics.
• Commercial mechanised grain farming and animal husbandry are increasing day by day in this region.

Though temperate grasslands are found in different parts of the world, their climate characteristics are almost the same. Short summers and long winters are the characteristics of temperate grasslands. These regions experience high temperature in summer as they are located at the interior of the continents. Average winter temperature ranges from 2° to 13° C.

Rainfall here ranges from 25 cm to 60 cm. Fluctuations in the rainfall availability are also reflected in vegetation. Due to less rain, trees are also few. Varieties of grass are generally found. Since temperate grasslands are natural grazing lands, most of the inhabitants are shepherds.

Nowadays, grasslands are widely converted into agricultural lands. Commercial mechanised grain farming and animal husbandry are increasing day by day in this region. The flora and fauna and the life of the people of each region are formed according to the climate characteristics. However, as part of the technological progress achieved over time, humans are changing the natural features of many areas.

Efforts to utilise all possible areas of the world will continue as long as there is ever-increasing population and human needs.

Prairie – The Granary of the World
The prairies, the temperate grasslands of North America, are often referred to as the world’s granary. Nearly two million acres of this vast grasslands, spread across the United States and Canada, are under commercial grain cultivation today. Wheat is the main crop. Moderate temperature, rainfall availability and fertile soil make this is region highly suitable for wheat cultivation. The large-scale production of wheat earned the prairies the title of the world’s granary.

COLD REGION

• Taiga region: It is a cold region located between latitudes of 55° and 70° in the Northern Hemisphere.
• Tundra region: Tundra region is the extreme cold zone extending from north of the Arctic Circle in Alaska, Canada, Greenland, and the Arctic coasts of Europe and Asia.

TAIGA REGION

• It is a cold region located between latitudes of 55° and 70° in the Northern Hemisphere.
• Short summers and long winters are experienced there. Summer temperature is from 15° C to 20° C while winter temperature drops up to -13° C to -25 ° C.
• This region receives an annual rainfall of 50 cm to 70 cm. In winter, precipitation is in the form of snowfall.
• Taiga is the Russian word for ‘coniferous trees’.

Taiga climatic region is absent in high latitudes of Southern Hemisphere because the extent of landmass is generally less. This region is dominated by sub-Arctic coniferous evergreen trees. Taiga is the Russian word for ‘coniferous trees’. This region is named as Taiga because of the abundance of such coniferous trees. Coniferous trees such as pine, fir and spruce are the main vegetation types.

• Most of the crops cannot be grown in sub-Arctic climates. Hence, the cultivation is very less in this region.
• Lumbering and wool industry are the main economic activities. Lumbering industry is very popular in Canadian Taiga region.
• As we move from the Taiga region to the polar region, the height of vegetation decreases and becomes sparse and less in number. Only frigid vegetation such as shrubs and mosses can be found in regions close to the Poles.

TUNDRA REGION

• Tundra region is the extreme cold zone extending from north of the Arctic Circle in Alaska, Canada, Greenland, and the Arctic coasts of Europe and Asia.
• Here winter temperature ranges from -25°C to -40°C and the summer temperature rises up to 10°C. Precipitation is mainly in the form of snowfall.

Only a few plants can survive in the harsh climatic conditions of the Tundra region. Plants grow only in summer. Due to the very short growing season available, short shrubs and mosses are the main plants found here. The native people of this region such as Eskimo, and Lappas lead a semi nomadic life. Arctics are the regions with relatively little human intervention. Scientists and explorers are continuing their studies in this region in search of future possibilities for mankind.

CLIMATIC CHANGE

• UN defines ‘climate change’ as a long-term shift in weather patterns and temperatures that is caused by human activity or natural variability.
• Global sea level is estimated to rise by 0.42 cm per year as a result of climate change.
• Earth’s climate has not always been the same; climate has undergone cyclic changes throughout the Earth’s history.
• Natural climate change resulting from endogenic earth processes cannot be controlled by human efforts.
• Activities such as industrialisation, land use change, and urbanisation are some of the human interventions that lead to climate change.
• Atmospheric temperature, pressure, winds, precipitation and humidity are the elements of climate.
• Climate change can be classified into two categories as natural and anthropogenic.

The timescale of climate change may range from a few years to millions of years. It affects ecosystems severely.

The first picture shows a cabinet meeting held at Mt. Everest, in Nepal, a country that belongs to the Himalayas, which is the highest point in the world. The second picture is of a cabinet meeting held underwater by Maldives, an island nation with an average elevation of just one and a half meters above the mean sea level.

These cabinet meetings were organised in a different manner to draw attention of the world nations to the problems of climate change. The mountain country of Nepal and the island nation of Maldives are among the countries most affected by global climate change. It is estimated that the Himalayan glaciers are melting at a rate of 12 to 20 meters per year as a result of global climate change. The increase in global temperature is causing rapid melting of glaciers and undesirable changes in ecosystem.

If the sea level rises by two and a half meters, the Maldives will be completely submerged in the sea. Global sea level is estimated to rise by 0.42 cm per year as a result of climate change. Atmospheric temperature, pressure, winds, precipitation and humidity are the elements of climate. Climate change results from the shift in quantity, distribution pattern, and seasonal pattern of these elements. It may affect a specific region or the whole world.

Earth’s climate has not always been the same; climate has undergone cyclic changes throughout the Earth’s history. Ice ages- and interglacial periods are examples of Earth’s natural climate change. Along with natural climate changes, human intervention also causes changes in the world’s climate. Therefore, climate change can be classified into two categories as natural and anthropogenic.

• Natural climate change resulting from endogenic earth processes cannot be controlled by human efforts. Climate change affects nature and human life in various ways.
• Human interventions often aggravate climate change. Climate change does not affect just one region alone, but it creates multi-faceted implications globally.
• Changes resulting from global climate change can be seen in the different climate zones of the world and their unique climatic characteristics. If this continues, it will destabilise the climate zones and adversely affect the ecological balance.

Greenhouse Effect and Global Warming
Certain gases in the atmosphere are capable of trapping solar energy (insolation) in the atmosphere. Such gases like carbon dioxide and nitrous oxide are known as Greenhouse Gases. Greenhouse gases allow sunlight to pass into the earth’s surface and keep the atmosphere warm by intercepting terrestrial radiation returning from the Earth’s surface. This process is known as the Greenhouse Effect of the Atmosphere. Some human activities result in excess production of greenhouse gases. Due to this, the greenhouse effect of the atmosphere becomes stronger and the temperature increases. This increase in atmospheric temperature is called Global warming. Burning of fossil fuels such as coal and petroleum, industrial effluents and solid waste are the sources of excess greenhouse gases in the atmosphere. Global warming accelerates climate change.

Activities such as industrialisation, land use change, and urbanisation are some of the human interventions that lead to climate change. International initiatives to protect the climate and environment have begun ever since it was noted that their activation may harmfully affect the climate and environment.

International initiatives	Year	Place	Interventions
Establishment of World Meteorological Organisation	1950	Geneva	Organises world climate conferences
Stockholm Conference	1972	Stockholm	Environmental conservation and development.
Earth Summit	1992	Rio de Janeiro	Prepared UN Agenda 21 to promote environment friendly development.
Kyoto Protocol	1997	Kyoto	Reduce the amount of Green House gases in the atmosphere.
Montreal Protocol	1987	Montreal	Reduce the production and consumption of ozone depleting substances.
Paris Agreement	2015	Paris	Reduce Global warming, helping world nations to cope up with the harmful effects of climate change.
G 20 Summit	2023	New Delhi	One earth, one family, one future. Green development, climate finance, overall development

Climate change cannot be completely prevented. But human intervention that induces climate change can be controlled.

Climate Refugees
Many people are being forcibly displaced by the impacts of climate change-induced disasters such as droughts, floods, desertification, sea-level rise, and sea inundation. They are forced to migrate to other regions or countries. Such migrations are called climate migration. UN figures indicate that around 50 million people have been displaced due to climate-related events. Those who have to leave their homes and livelihood due to climate-related phenomena are called climate refugees.

Millions of people of the world’s ever-increasing population depend on the climate for their livelihoods. Even a small change in climaig can affect the lives of people adversely. Therefore, it is essential to control activities that cause climate change. Since climate change is not a problem that affects only one region or country, it is essential for all the nations to work together for the sustainable existence of human life.

Information from study reports conducted by international agencies on the effect of climate change are given below. Based on these, gather more information and organise a discussion on the challenges of climate change.

Although there was a parliament called the Estates General, it was not summoned for a long time. The most prominent of the Bourbon kings was Louis XIV, who declared, “I am the State” Corruption, extravagance and continuous wars waged by Louis XV, who succeeded Louis XIV, put the country and its people in misery. Louis XVI, who came to power later, did not pay much heed to governance. The queen’s extravagance made the people unhappy.

Question 21.
Define Divine Right Theory.
Answer:
According to the Divine Right Theory, the king is the representative of God. The king derives his authority from God. Flence, they are not accountable to the people but to God. Those who supported the despotic rule believed in this theory.

Question 22.
French society in the 18^th century was divided into three estates. Which are they? Explain.
Answer:
a) The Clergy (First Estate): The Catholic Church in France was very powerful and wealthy. The church owned large tracts of land. The clergy was exempted from all types of taxes. Moreover, they levied a tax called the tithe on the common peasants. One-tenth of the total produce was remitted as tax. This made the common peasants resent the clergy.

b) The Nobles (Second Estate): The nobles held the highest positions in government and in the army. They were landowners as well. The nobles, who lived luxuriously, collected various taxes from the people. According to an act of 1749, all sections of people had to pay one-twentieth of their income directly to the government as tax. This tax was known as Vingtieme. The first two estates (the clergy and the nobles) got exempted from the tax by giving a small amount to the king as a gift. The priests and nobles never hesitated to oppose the monarchy to maintain their rights.

c) The Commons (Third Estate): The third estate in France comprised of the middle class, workers and peasants. They were known as Commons. Most of the third estate, which comprised the majority of the population, lived in poverty.

Question 23.
Describe three different ways in which the nobles exploited the common people in 18th-century France.
Answer:

• Corvee: The right to make the common people work for three or four days a year without paying any reward.
• Banalite: The additional tax obtained from the monopoly of wine making and the rent for the compulsory use of the landlord’s facilities for the manufacture of grape juice, bread, etc.
• Banvin: A monopoly tax on the wine produced in the territory of a lord.

Question 24.
Explain the reasons behind the rise and discontentment of the middle class in 18th-century France. Answer:
The rise of the middle class in 18th-century France was due to progress in agriculture and industry, which led to the growth of cities and new job opportunities. Wealthy industrialists, doctors, lawyers, and bankers became part of this class. Despite their education and economic success, they had to pay taxes like the common people and were denied power and status in administration and the army. This led to deep discontentment among them.

Question 25.
What role did Turgot and Necker play in France’s economic reforms, and why did their efforts fail? Answer:
Turgot, an advisor to Louis XVI, introduced reforms to improve agriculture and promote free trade to help the middle class and revive the economy. However, Queen Marie Antoinette opposed his cost-cutting measures, leading to his dismissal. Necker continued the reforms but was removed due to France’s war with England and opposition from the National Assembly. Later, advisors also failed, and eventually, the king had to recall Necker.

Question 26.
What were Rousseau’s main ideas, and how did they influence the French Revolution?
Answer:
Rousseau was a political theorist and educational philosopher who believed in the natural freedom of man. In his work The Social Contract, he argued that the people created the king through a contract for their welfare, and if the king violated it, he lost the right to rule. His statement, “Man is bom free, but everywhere he is in chains,” reflected his opposition to the power structure. His ideas inspired the people to rise against injustice, contributing to the French Revolution.

Question 27.
Why was the Estates General summoned after 175 years, and what problems arose during its organisation?
Answer:
The Estates General was summoned by Louis XVI, on Necker’s advice, to address the severe economic crisis by imposing new taxes. Problems arose because the three estates met separately and followed the old system of one vote per house, favouring the clergy and nobility. The Third Estate, which represented the majority population, demanded a joint session and more fair representation, but the first two estates rejected their demand.

Question 28.
What major reforms were introduced by the French National Assembly after the Revolution?
Answer:

• Implemented a unified constitution throughout the country
• Issued a new paper currency called ‘Assignat’
• Confiscated the properties controlled by religious leaders
• Declared complete religious tolerance

Question 29.
Define Continental System.
Answer:
Napoleon’s arch-enemy was Britain. He devised plans to destroy Britain economically as he knew that it would be impossible to conquer Britain, which was a superior naval power. The plan formulated for this purpose is known as the “Continental System”.

Question 30.
What are the main ideas highlighted in the Declaration of Human Rights of France in 1789?
Answer:

• Men are born and remain free and equal in rights.
• The aim of all political associations is the preservation of the natural and inseparable rights of man. These are the rights to liberty, property, security, and resistance to oppression.
• The principle of all sovereignty resides essentially in the nation. Liberty consists of the freedom to do everything that injures no one else.
• The law can only prohibit such actions as are hurtful to the society.

Question 31.
What is September Massacre?
Answer:
Thousands of people, including nobles, priests, and supporters of the king, were branded as traitors and imprisoned. When the prisons overcrowded, about one thousand and five hundred people were killed on the streets of Paris. This is known as the infamous “September Massacre”.

c) National Convention came into being
d) New constitution came into being in France
e) Congress of Vienna

Question 37.
What factors led to the rise of the middle class in 18th-century France, and why were they discontented?
Answer:
The rise of the middle class in 18th-century France was due to progress in agriculture and industry, which led to the growth of cities and new job opportunities. Wealth from domestic and colonial trade helped industrialists become part of this class, along with professionals like doctors, lawyers, and bankers. Despite their education and economic progress, they had to pay taxes and were denied proper status and power in administration and the army, leading to deep discontentment.

Question 38.
Who were the Jacobins and the Girondists?
Answer:
The Jacobins were a political and social group that emerged during the French Revolution. They met at the Jacobin Convent in the early days. That is why they were called Jacobins. Robespierre was a major leader of this group. Another major group that participated in the French Revolution were the Girondists. Some of them were members of the National Assembly who came from the Gironde region in south western France. Unlike the Jacobins, they took a moderate position. They were representatives of the upper classes, who were landowners and merchants.

Question 39.
What were the main reasons behind the economic crisis in France during the 1770s, and how did it lead to public unrest?
Answer:
In the 1770s, the French agricultural sector faced a severe crisis. This was due to a decrease in production.

This led to an increase in the price of cereals and bread. Between 1730 and 1789, the price of cereals increased by 60 percent. However, the increase in wages was only 22 percent. A severe shortage of fodder saw a huge decline in livestock. This affected one-third of the population adversely. According to the trade agreement signed by France with Britain, there was a huge reduction in import duties on British products. The French market was flooded with British products and made native artisans unemployed. Thus, disgruntled farmers, artisans, and other workers took to the streets against the government. To overcome the economic crisis, King Louis XVI borrowed huge sums from bankers. In exchange for these loans, the government issued bonds. The empty coffers discouraged bankers from lending more money. One of the main reasons why the middle class, which included bankers, opposed the government was this inequality in taxation. They demanded that rules of taxation should be made equal among all citizens.

Question 40.
Explain the background of the French Revolution.
Hints:
• Despotic regime
• Social System
• Middle class
• Influence of French Thinkers
Answer:
Despotic regime
There was a public uprising against the despotic regime that existed in France. The Bourbon dynasty was ruling France for decades. They believed in the divine right of rulers. Although there was a parliament called the Estates General, it was not summoned for a long time. The most prominent of the Bourbon kings was Louis XIV, who declared, “I am the State”. Corruption, extravagance and continuous wars waged by Louis XV, who succeeded Louis XIV, put the country and its people in misery. Louis XVI, who came to power later, did not pay much heed to governance. Queen’s extravagance made the people unhappy.

Social System
French society in the 18th century was divided into three estates. The clergy in the first, the nobles in the second and the common people in the third estate. The church owned large tracts ofland. The clergy was exempted from all types of taxes. Moreover, they levied a tax called the tithe on the common peasants. One-tenth of the total produce was remitted as tax.

The nobles held the highest positions in government and in the army. The nobles, who lived luxuriously, collected various taxes from the people.

The third estate in France comprised of the middle class, workers and peasants. They were known as Commons. Most of the third estate, which comprised the majority of the population, lived in poverty. They were obliged to pay various taxes to the king, the church and the nobles. In addition, they had to perform services that were unpaid and compulsory. Some of them included:

• Performing military service when it was necessary
• Providing free service for the construction of public roads, waterways, bridges, etc.

Middle Class: A middle class emerged in French society in the 18th century. The progress made in the agricultural and industrial sectors of France at that time led to the rise of the middle class. With the growth of the agricultural and industrial sectors, new cities emerged. Those who took advantage of the employment opportunities in the cities progressed economically and became part of the middle class. This middle class, like the common people, also had to pay taxes to the government and the nobility. Despite their educational and economic advancement, they were not given the status or power they deserved in the administration and the army. In short, the middle class had deep discontentment.

Influence of French Thinkers

• Voltaire: Voltaire was a philosopher, historian, satirist, and a philanthropist. Though he was not an atheist, he constantly criticised the clergy through his articles. He was expelled from France due to his stance and writings.

• Rousseau: Rousseau was an educational philosopher and a political theorist. His work, The Social Contract, defined the relationship between the citizen and the state. Rousseau stated, “The people created the king through a contract for their welfare and upliftment. However, the king has violated his responsibilities. Therefore, he has lost the right to rule.” He argued that, “good laws create good citizens.” Rousseau opposed the existing power structure. His ideas were based on naturalism. “Man is born free, but everywhere he is in chains,” he said. Rousseau’s works inspired the French Revolution.

• Montesquieu: Montesquieu criticised the evils of the church and the tyranny of the state. He advocated limited monarchy and proposed that powers of the government be divided into three branches: the legislative, executive, and judicial, to ensure the freedom of individuals. His famous work The Spirit of Laws, analyses the principles of government and the evolution of law and the constitution.

The ideas of the British philosopher John Locke also had a decisive impact on the French. His famous work, Two Treatises of Government, rejected the divine right and tyranny of the king. Economists known as ‘Physiocrats’ also influenced the French people. Prominent among them were Turgot and Necker. Turgot, was an advisor to Louis XVI, who conceived many plans to improve the economic situation of France. These economic policies reflected the interests of the middle class. Encouragement of agriculture and free trade of food items were important among them.

Question 41.
Write a short note about the Estates General meetings.
Answer:
To overcome the severe economic crisis of France in the 18th century, it became necessary to impose new taxes. For this, Louis XVI, on the advice of Necker, decided to summon the French parliament, the Estates General. When the Estates General was convened again after 175 years, disputes arose regarding its organisation. Like the French society, the Estates General was also divided into three. The three estates met separately. The Clergy, which was only a small percentage of the French population, had two hundred and eighty-five members. The nobility, which numbered only about one hundred and forty thousand of the French population, had three hundred and eight members in the House of Representatives. The common people, who constituted the majority, had six hundred and twenty-one members in the House of Representatives. The membership of the first and second estates was by inheritance. However, the members of the Third Estate were elected.

The existing system was one vote for one house. The first two houses supported this. The reason for this was that if the first and second estates came together, they would have a majority to control the government. All the new representatives of the Third Estate presented the grievances and demands of the groups that they represented. However, King Louis XVI did not make any preparations to resolve these problems. The main reason for this was that the king did not have enough knowledge of the parliamentary system.

Though representatives of the Third Estate demanded the meeting of all three estates together, the first two estates refused to do so. Following this, on 17 June 1789, the members of the Third Estate declared themselves the real representatives of the people of France and called their assembly the’ French National Assembly.

With the support of the first two estates, Louis XVI closed the hall where this assembly used to be held and placed it under-military guard. Led by Jean-Sylvian Bailly, the Abbe Sieyes, and Mirabeau, the representatives of the Third Estate met on 20th June at the nearby tennis court. They declared that they would not leave until they draft a constitution for France. This was later known as the “Tennis Court Oath”. This session of the National Assembly later came to be known in history as the “Tennis Court Assembly”.

Write any two consequences of French Revolution.
Answer:
The most obvious result of the French Revolution was the collapse of feudalism in France.

The laws of the old regime disappeared with the revolution. The land owned by the church became the property of the middle class. The land under the nobles were confiscated and all kinds of benefits were abolished. With the introduction of a unified system of weights and measures (the metric system), the inaccuracy in weights and measures ended. The concept of modern nationalism is a contribution of the French Revolution. It was only after the French Revolution that the existence of a nation began to be expressed through national character, not through monarchy.

The concept of the nation in its full sense came into being after the French Revolution. This declared the idea that France was not just a geographical expression, but the entire people of France. Another concept that grew with nationalism is the democratic system of governance. It was after the French Revolution that the foundation of democratic rule based on Rousseau’s idea of the sovereignty of the people was realised. The French Revolution also influenced the struggles for national independence that took place in Asia and Africa in the nineteenth and twentieth centuries.

Answer:
The Role of Public Opinion Formation in Strengthening the Democratic Process
Democracy is a political system that ensures equal participation of all the people of a country. It is based on the principle that the government is for the people, by the people, and of the people. As a system that ensures public participation, democratic governments formulate their policies and programmes by considering the opinions and interests of the people. Public opinion, which reflects the collective thoughts and concerns of citizens, plays a key role in strengthening democracy. The elections conducted within a democratic system are also largely influenced by public opinion, as people vote based on their understanding of issues, party promises, and the performance of leaders. In a democratic system, civil society makes the rulers responsible through constant criticism and active participation in social and political matters.

Public opinion acts as a powerful tool to question the misuse of power and helps in maintaining the rule of law. In such a society, citizens are fully aware of their rights and duties, and they hold the government accountable. Arbitrary and dictatorial tendencies are prevented when public opinion is strong, and the rights and freedoms of individuals are safeguarded. A society with strong public opinion encourages critical thinking, responsible political behaviour, and continuous dialogue. It also compels political parties to act responsibly and address public concerns effectively. Thus, public opinion, as the consolidated voice of the people, plays a vital role in upholding the values of democracy and ensuring a government that truly represents its people.

Civil society is an important idea in democracy. It includes organisations, groups, and people who work for the welfare of the society. They do this voluntarily, without government control or profit motive, and they represent different views and ideas.

CHARACTERISTICS OF PUBLIC OPINION
The influence of public opinion on social life, governance and politics is enormous. Public opinion is formed when responsible citizens brings out the problems in the society to the attention of others, it is an effective social control over the government and it encourages debate that empowers democracy. Public opinion is considered as one of the essential criteria of democracy. Social and cultural background of individuals, attitude, belief, preconceptions, leadership skills, education etc are the factors that influence public opinion.

• Public opinion reflects diverse opinions.
• Public opinion is not necessarily the views and opinions of the majority of people but, is the creation of a general consensus on a topic.
• Public opinion may change with the circumstances, time and new knowledge.
• Public opinion is always formed not only on political matters but also in relation to Socio-economic and cultural matters.
• There is no fixed place from where one can express public opinion and anyone can express their opinion from any where.
• Public opinion ensures democratic communication.

AGENCIES THAT SHAPE PUBLIC OPINION
Formation of public opinion is not an automatic, highly precise or perfectly timed process. Various sections of the society express their opinion and views whenever a common issue arises in the society. In this process some comments are very much welcomed and it emerges as the public opinion. Thus public opinion is formed through formal and informal processes. Family and educational institutions play an important role in developing public opinion which, in turn, empowers democracy. Peer groups, media, political parties, social institutions and organisations, opinion polls, art and literature etc. also contribute in this. All these are different agencies that shape public opinion.

FAMILY
A child’s socialisation process starts from the family and the traditional beliefs and perceptions of the family, influences opinion formation. The child is a participant or a witness in the discussion held in the family in which politics, beliefs, religion, literature, etc. are all topics. In this way, the family has the first place in the formation of the child’s opinion on various issues.

EDUCATIONAL INSTITUTIONS
Educational institutions play a major role in shaping and developing the child’s knowledge, rights, duties, scientific thinking, critical thinking, and culture. All knowledge and skills are acquired by the child mainly through educational institutions. The process of education helps a person to form an independent and rational opinion on any subject. Educational institutions play an important role in shaping children’s understanding of various subjects. Activities in school such as school parliament, club activities, sports and cultural activities act as a platform in developing democratic and civic sense among the students. Such activities provide enough avenues for the learners to express their opinions and that develops skills in forming public opinion.

PEER GROUPS
Debates and discussions among peer group members are important factors influencing public opinion formation. Peer grqup members share almost common characteristics in terms of personality, attitudes and behaviour which are important factors influencing public opinion formation. They all share some common characteristics in their personal experiences and social influences. Peer group members can influence each other on the policies of the government, various social issues and political parties. Such peer group discussions are helpful in eliciting common opinions, correcting existing ones and arriving at correct opinions. This debate and discussion lead to the formation of public opinion.

Peer Groups
Peer Groups are groups of similar age and with similar interests and goals. Peer groups tend to be similar in their beliefs,values and ideals.

MEDIA
Media play an important role in shaping public opinion. News, discussions and advertising programmes available through traditional media (print media, radio and television) and new media (Digital and social media) have a great influence on people. Media can bring an issue to public attention and shape public opinion on it.

a) Newspapers
Newspapers play an important role in bringing all political and social events before the public. Newspapers are able to strengthen the democratic process by bringing current issues to the people and at the same time bring the opinion of the people to the government. There fore newspapers play a key role in shaping public opinion. The influence of newspapers help not only in forming public opinion but also in changing and diverting it according to certain interests. Sometimes some news does not necessarily have to be factual and it can mislead the public opinion. Due to vested interest, wrong news might reach people through online newspapers, etc. There is a criticism that impartial approach and accuracy in the news are not often from the side of the media.

b) Radio, Television
Radio and television are serving as a mirror to social life. While the print media considers only the literate community, radio and television play an important role in forming the ideas and knowledge among the illiterate community. Radio and television play a significant role in sharing the opinions and thoughts of the people in the society about various policies and programmes of the government.

c) Social Media
Today social media and all mainstream media have an important role in forming public opinion.In the modem age, almost all people in the society are communicates through digital platforms. Everybody should recognise such traps in the digital world. We have to acquire digital and media literacy.

• Media literacy is the ability to access, analyse, evaluate, create new messages and communicate the messages received through various forms of media.
• Content creation and the way it shapes our perceptions and how we critically interpret news and messages are all included in this.
• Media literacy includes the way we shape our perceptions and critically interpret news and messages.
• Digital literacy is the ability to find information from the digital world and evaluate them efficiently using digital equipment and technology.
• This includes basic computer knowledge, effective use of internet, navigation of digital platforms, critical evaluation of online content, cyber awareness, etc.
• Digital literacy is how we effectively use digital tools and technology to find out and evaluate information from digital spaces.

“In the very first month of’Indian Opinion’, I realised that the sole aim of journalism should be service. The newspaper press is a great power, but just as an unchained torrent of water submerges whole countrysides and devastates crops, even so an uncontrolled pen serves but to destroy. If the control is from without, it proves more poisonous than want of control. It can be profitable only when exercised from within. If this line of reasoning is correct, how many of the journals in the world would stand the test? But who would stop those that are useless? And who should be the judge? The useful and the useless must, like good and evil generally, go on together, and man must make his choice.”
(Mahatma Gandhi, ‘The story of My Experiments with Truth’)

POLITICAL PARTIES AND THEIR ACTIVITIES

• Political parties and their activities are at the forefront of shaping, and mobilising public opinion in the democratic system of government.
• Both ruling and the opposition parties play a role in shaping public opinion.
• The main objective of political parties is to make the public think about common public issues politically.
• Each political party publishes journals, pamphlets, manifestos, posters, write ups etc. to create public opinion in their favour.
• Along with that conference, demonstrations, rallies and seminars are all organised for the formation of public opinion.

Ruling parties try to propagate government policies in their favour. They also devise appropriate campaign strategies. On the other hand, the opposition parties bring the shortcomings and failures of the administration to the attention of the people and they undertake campaigns and struggles that help in the formation of public opinion against the government. All political parties have an interest in promoting their own ideals during election stages. Every party and front tries to gather the maximum support of the people presented through the manifesto.

Political parties try to intervene and form opinions on all the important issues facing the society and the state through their election manifestos. Every party tries to mobilise the people in its favour by presenting their views and ideas and makes them involved in public affairs and ensure participation in the electoral process. During the election campaign parties try to sway public opinion in their favour. Even after the completion of election process the political parties keep on campaigning on public issues. When political parties go overboard and engage in personal attacks and negative propaganda, the election commission intervenes and controls them.

SOCIAL INSTITUTIONS AND ORGANISATIONS
Various social institutions and organisations working in society play a crucial role in shaping public opinion. Religious institutions, caste-religious organisations, student movements, youth movements, women’s equality movements, trade unions, human rights movements, merchant associations, environmental organisation etc. play their own role in shaping public opinion.

OPINION POLL
Opinion polls are a very effective way to gather information about public attitudes and opinions on various social, cultural, political and economic issues. A sample of population is approached for their views regarding specific issues. By using the information public opinion can be formed. There are various professional agencies working to conduct opinion polls.

ART AND LITERATURE
Art, literature, cinema of each era influence the formation of the public opinion of the times. “Patta Bakki”, “Adukkalayil Ninnu Arangathekku” and so on were some of the plays which had a significant role in changing the social life of Kerala. Literary works of Rabindranath Tagore, Subramania Bharathi and Vallathol Narayana Menon inspired Indian freedom movement.The art forms such as Ottanthullal, Chakyarkoothu, etc could form strong public opinion against the then existing social evils, customs and thereby ignite social revolution. Various art forms and literary works influence our tastes and interests.

Eg: “ Chandalabhikshuki” by Mahakavi Kumaran Asan is a work which had a strong influence in forming public opinion against social evils based on caste system such as untouchability. Some lines from that poem

“ദാഹിക്കുന്നു ഭഗിനീ കൃപാരസ-
മോഹനം കുളിർ തണ്ണീരിതാശു നീ
ഓമലേ, തരു തെല്ലെ”ന്നതു കേട്ടൊ
രാ മനോഹരിയമ്പരന്നോതിനാൾ:
“അല്ലല്ലെന്തുകഥയിതു കഷ്ടമേ!
അല്ലലാലങ്ങു ജാതി മറന്നിതോ?
നീചനാരിതൻ കൈയാൽ ജലം വാങ്ങി-
യാചമിക്കുമോ ചൊല്ലെഴുമാര്യന്മാർ?
ഓതിനാൻ ഭിക്ഷുവേറ്റം വിലക്ഷനായ്:
“ജാതി ചോദിക്കുന്നില്ല ഞാൻ സോദരി,
ചോദിക്കുന്നു നീർ നാവുവരണ്ടഹോ
ഭീതിവേണ്ടാ തരികതെനിക്കു നീ.”

This scenario is Anandan, a Buddhist monk, requesting drinking water from a girl who was drawing water from a well beside the path. However, she hesitates, explaining that she belongs to a lower caste and that giving him water would be considered a sin. Anandan, undeterred, says, “I did not ask your caste, but water,” compelling her to comply. His response, which disregarded caste distinctions and addressed a lower-caste woman as his sister, was a revolutionary act in the social context of that time.

FACTORS THAT HINDER THE FORMATION OF PUBLIC OPINION
Democracy will be stronger where public opinion is strong. The limitations of democracy can be corrected and guided in the right direction with strong public opinion. However, there are some factors that hinder the formation of public opinion in society.

Illiteracy: Illiterate people have only limited knowledge about public issues. They may not have the capacity to form rational opinions.

Digital Divide: The digital divide is the gap in accessing modem information technology such as the internet, computer, and smartphone. This hinders the formation of effective public opinion.
Poverty: Groups experiencing poverty are often isolated from public affairs. Hence, they are not able to participate in the formation of public opinion appropriately.

Unhealthy political activity and lack of democracy in political parties: Partisanship in political activities and polarisation among the people are factors that hinder the formation of public opinion.

Unhealthy practices during the election campaigns: Unhealthy practices that are used to influence voters during election times often hinder the formation of real public opinion. In addition to these, corruption, regionalism, other socioeconomic, cultural and parochial group interests, and hero worship are all factors that undermine true public opinion.

Democracy is a political system that ensures equal participation of all the people of a country. As a system that ensures public participation, democratic governments formulate their policies and programmes by considering the opinions and interest of the people. In addition, the elections conducted within a democratic system, are also chiefly influenced by the opinions of the people. In a democratic system, civil society makes the rulers responsible through constant criticism. Public opinion can question the exercise of power and regulate the rule of law. In such a society, the people are fully aware of the rights and duties of citizens. Arbitrary and dictatorial tendencies are prevented in a society with strong public opinion and the rights and freedom of citizens are protected. In a society
with strong public opinion, every issue is critically evaluated and it makes political parties responsible. Public opinion, as the consolidated opinion of the people, plays a key role in democratic systems.

Briefly explain the colonial perspective of European Renaissance.
Answer:
Several arguments have emerged of late challenging the conventional view that the Renaissance originated in Europe. Works like Stolen Legacy by George James, Black Athena: The Afroasiatic Roots of Classical Civilisation by Martin Bernal present alternative perspectives. They are of the view that colonial historians have perpetuated a Eurocentric narrative, portraying Europe as the sole hub of civilisation. They dismissed the contributions of other cultures. According to these critics, this biased approach has led to the marginalisation of non-European cultures, implying that only Europeans are civilised while others are uncivilised.

As part of this initiative, the Church leadership convened the Council (Synod) of Trent in Northern Italy. The objectives of this council were to correct erroneous tendencies within the Church and to implement reforms. As a result, the sale of indulgences was banned. A list of books (The Index) that the believers should not read was published. The court of inquisition, which was there in Medieval times, was reinstituted. ‘The Society of Jesus, set up by Ignatius Loyola, a Spanish priest, also played a prominent part in Counter Reformation. Its members were bound to observe strict discipline and unquestioned obedience. They tried to establish the authority of the Catholic Church by setting up schools and engaging in active missionary work. Counter Reformation succeeded in eliminating a number of wrong tendencies in the Catholic Church. Counter¬Reformation is also known as Catholic Reformation.

Question 20.
Explain the transformation in the field of Astronomy during the renaissance period.
Answer:
Remarkable transformations took place in the field of astronomy during this period. The geocentric model of Ptolemy, which positioned the Earth at the center of the universe, remained unchallenged until the 16th century. Later, Nicolaus Copernicus, a Polish astronomer and priest, challenged this prevailing doctrine. He presented a revolutionary argument that the centre of the universe is not the Earth but the Sun. Through his observations, Copernicus demonstrated that the Earth and the other planets revolve around the Sun. Kepler’s path-breaking findings revealed that the speed of planets varied based on their distance from the Sun, which laid the foundation towards the end of the 17th century for Isaac Newton’s formulation of the theory of gravitation. Galileo’s findings provided conclusive evidence in support of Copernicus’ principles.

Question 21.
What are the classifications made by Flavio Biondo and Leonardo Bruni?
Answer:
The classification made by them was:

• the Ancient Period, spanning up to the 5th century CE;
• the Medieval Period, extending from the 5th to the 15th century;
• and the Modem Period, encompassing the era thereafter.

• Traders in these cities were well aware of banking and insurance. Some of them had expertise in technical matters of trade, such as bookkeeping.
• Many of them had become extremely wealthy through trade.
• Italian cities got acquainted with the cultures, cities, and lives of the people in the Eastern world. This accelerated the growth of Italian cities. As a result of trade links with the Islamic Empire and the Byzantine empire, enormous wealth flowed into the Italian Cities.
• Merchants in Italian cities gained a monopoly in the trade between the East and West in the Mediterranean.

Question 23.
What is meant by scholasticism?
Answer:
The Middle Ages were predominantly influenced by the philosophical school of thought known as * scholasticism, which was deeply rooted in Christian theology. Humanism emerged as a departure from Christian theology, emphasising the significance of human experience, worldly life and rational inquiry. Humanists highlighted the uniqueness, emotions, capabilities, literary expression, and communication skills inherent in humanity. This paradigm shift was founded on a transformation from a theological perspective to a human- centered outlook. Humanism also accommodated dissenting voices and criticism, questioning the authority of religious dogma and domination.

Question 24.
Define the role of Architecture in Renaissance.
Answer:
Architecture was another field that witnessed transformation besides painting and sculpture. Filippo Brunelleschi set a new style in architecture. Quite different from the Gothic architectural style of the medieval period, the influence of ancient Greco-Roman (classical) style is evident in the Cathedral he built in Florence. The lofty towers found in Gothic style were replaced with domes (Dumo). Later, in St. Peter’s Basilica, built under the supervision of Michelangelo and Bramante, this style is more evident.

Gothic style: Gothic style developed in Europe in the second half of the Middle Ages. It originated in France. The pointed arch was its striking feature. A large number of churches and universities were built in Europe in this style.

Question 25.
How did the Renaissance influence the modern world?
Answer:
The Renaissance was a period of great cultural, artistic, and intellectual awakening that transformed Europe and had a lasting impact on the modern world. It encouraged people to think critically and explore new ideas in science, art, and literature. The invention of the printing press by Johannes Gutenberg helped spread knowledge quickly, leading to an increase in literacy and education. Renaissance artists like Leonardo da Vinci and Michelangelo created masterpieces that set new standards for art and architecture. Writers like William Shakespeare and Dante introduced new literary styles that are still admired today.

In science, thinkers like Copernicus and Galileo challenged traditional beliefs and laid the foundation for modern astronomy and physics. The Renaissance also promoted humanism, which emphasised individual potential and the importance of questioning authority. These ideas influenced later movements like the Enlightenment and the democratic revolutions in many countries. Overall, the Renaissance played a key role in shaping modern education, government, and scientific progress, making it one of the most important periods in world history.

Question 26.
What are the features of Renaissance paintings?
Answer:

• Landscapes
• The use of colour to illustrate light and spatial depth

Question 27.
Explain the renaissance in Italy using the following Hints:
a. Commercialisation
b. Crusades
c. Black Death
Answer:
The commercialisation that occurred in Europe by the 11^th century led to the disintegration of the medieval feudal system and the decline of religious supremacy. This led to the emergence and domination of the new wealthy class. As a result, several wealthy families also emerged in Italy.

The Crusades that took place during the medieval period facilitated cultural exchange between the East and the West. Italian cities got acquainted with the cultures, cities, and lives of the people in the Eastern world. This accelerated the growth of Italian cities. Merchants in Italian cities gained a monopoly in the trade between the East and West in the Mediterranean.

The Crusades: The wars fought between believers of Islam and Christianity over Jerusalem, which was considered a holy land by both, are known as Crusades. The crusades that took place from the 11^th to 13^th century had a profound impact on the political, social and economic lives in both Europe and Asia.

The Bubonic Plague, which empted in the mid-14th century, several affected the Italian cities. This catastrophic event, known as the ‘Black Death,’ claimed the lives of thousands, resulting in a severe shortage in labour.

The Black Death is the epidemic that ravaged Europe between 1347 and 1351. Black boils appeared on those who were affected by the disease. That is why the disease is known as Black Death. This epidemic spread through the fleas carried by rats that reached European ports via merchant ships.

Shortage in labour

• This paved the way for the decline of medieval feudalism, which was heavily reliant on the agricultural sector. Furthermore, it facilitated the emergence of a new commercial middle class.
• When traditional medicines failed to fight the plague, people began to explore the medical sciences of ancient Greece and Rome. The terrors of the plague prompted human beings to contemplate the fleeting nature of life, seek wellness, and focus on their own well-being. This introspection paved the way for the emergence of humanism.

Question 28.
Explain the role of Art in Renaissance.
a. Painting
b. Sculpture
c. Architecture
Answer:
a. Paintings
Humanistic ideals were reflected profoundly in Renaissance paintings. Painters of the time presented human forms with remarkable accuracy, clarity, and meticulous attention to detail in their works. The knowledge they had acquired about human anatomy facilitated this artistic achievement.

Moreover, painters emphasised rationalism and human emotions, attributing significance to the values of this world. With the influence of humanism, artworks became increasingly precise and realistic. Painters often selected themes that emphasised theological significance for their works. However, Renaissance paintings had certain other distinctive features as well:

• Landscapes.
• The use of colour to illustrate light and spatial depth.
• Realistic depiction of the human body.
• The use of oil paint
• Portraits
• The representation of divine figures in idealised human forms.

The influence of Greco-Roman art was first evident in Giotto’s works. However, it was Masaccio, a painter who emerged later created a profound impact on all artists who came later. His wall paintings, characterised by their round shape and seeming to protrude from the surface, showcased human figures. Engaging in everyday life experiences. The Last Supper and Mona Lisa are world-famous paintings by Leonardo da Vinci. These paintings speak of the unique way in which da Vinci harmonises colour, shadow and light. He was a versatile genius who scientifically studied the human body.

In the ‘Last Supper,’ emotions like surprise, fear and guilt of Christ’s disciples are vividly etched as Christ reveals that one of them betrayed him. It is widely acknowledged that the enigmatic expressions of the Mona Lisa conceal many unanswered questions masterfully embedded by Leonardo da Vinci.

• The paintings done on the ceiling of the Sistine Chapel at the Vatican, along with The Last Judgment,’ have cemented Michelangelo’s status as an immortal artist. His works predominantly feature powerful and graceful human forms.
• Other notable painters of the Renaissance period include Titian and Raphael. Raphael portrayed humans as wise, moderate, and dignified. In their paintings, beauty and ideas were given equal importance.

b. Sculpture
Sculpture was another equally notable field of Renaissance art. Donatello was one of the most important sculptors of the Renaissance period. He liberated the art of sculpture from the medieval Gothic style, giving his works greater power and individuality. His iconic bronze sculpture, David, showcases a youthful figure standing with his weight shifted onto one leg. Another notable work, ‘Gattamelata, depicts a soldier sitting on horseback, evoking the cavalrymen of ancient Rome. Through this masterpiece, Donatello immortalised a secular hero.

Michelangelo’s sculptures, which depicted Gods in human forms, deviated significantly from the traditional ancient Greco-Roman style. His renowned works, such as the ‘Pieta’, which portrays the Virgin Mary with Jesus Christ on her lap and the majestic sculpture of ‘David ‘, have cemented his legacy as an immortal artist.

C. Architecture
Architecture was another field that witnessed transformation besides painting and sculpture. Filippo Brunelleschi set a new style in architecture. Quite different from the Gothic architectural style of the medieval period, the influence of ancient Greco-Roman (classical) style is evident in the Cathedral he built in Florence. The lofty towers found in Gothic style were replaced with domes (Dumo). Later, in the St. Peter’s Basilica, built under the supervision of Michelangelo and Bramante, this style is more evident.

Question 49.
How did the Renaissance contribute to the classification of history?
Answer:

• This classification divides history into three distinct periods:
• the Ancient Period, spanning up to the 5th century CE;
• the Medieval Period, extending from the 5th to the 15th century;
• the Modern Period, encompassing the era thereafter.
• This classification emerged during the Renaissance period. It was introduced by two Italian historians, Flavio Biondo and Leonardo Bruni.

The transition from medieval Christian tradition to a secular life and thought was also reflected in the realm of historiography. During the Middle Ages, the prevailing notion was that historical events were divinely ordained and supernatural powers governed the course of history. This perspective lost its relevance during the Renaissance period. Instead, human-centered explanations and interpretations gained recognition. Human life became the focus of historical narratives, superseding the chronicles of monks and biographies of priests.

• Another significant development in historiography during the Renaissance was the growing importance of archaeological evidence and relics. Thus, historians began to place greater emphasis on evidence such as inscriptions, coins, and ancient manuscripts in their narratives. Furthermore, efforts to collect and preserve ancient manuscripts intensified.
• With the emergence of humanism, critical thinking gained significance in history. Scientific enquiry and studies replaced stories and myths. The contributions of Machiavelli to Renaissance historiography are noteworthy.

Question 50.
How did the Renaissance change the way historical events were interpreted?
Answer:
During the Middle Ages, history was seen as divinely ordained, with supernatural forces guiding events. The Renaissance shilled this perspective towards human-centered explanations, focusing on real-world causes and human agency instead of religious interpretations.

Question 51.
Who introduced the classitication of history into three periods?
Answer:
Flavio Biondo and Leonardo Bruni

Question 52.
How did humanism influence historiography?
Answer:
It promoted critical thinking, scientific inquiry, and fact-based historical writing.

Question 53.
The Renaissance laid the foundation for the …………………….
Answer:
evolution of modem science.

Question 54.
How did Galileo Galilei and Johannes Kepler expand on Copernicus’s discoveries?
Answer:
Galileo supported Copernicus heliocentric theory with telescope observations, including Jupiter’s moons and Venus phases. Kepler further proved it by discovering that planets move in elliptical orbits.

Question 55.
Who formulated the theory of gravitation?
Answer:
Isaac Newton

Question 56.
What was the geocentric model, and how did Copernicus challenge it?
Answer:
The geocentric model, proposed by Ptolemy, placed the Earth at the center of the universe. Copernicus challenged this by arguing that the Sun, not the Earth, is the center of the universe. He demonstrated that the Earth and other planets revolve around the Sun.

Question 57.
How did Galileo Galilei support Copernicus heliocentric theory?
Answer:
Galileo provided conclusive evidence in support of Copernicus’ theory by using a telescope to observe celestial bodies.

Question 58.
How did the Renaissance influence religion in Europe?
Answer:
The Renaissance encouraged critical thinking and humanism, which led scholars to question religious practices and church authority, eventually contributing to the Protestant Reformation.

Question 59.
Why did some rulers support the Reformation?
Answer:
Many secular rulers wanted to reduce the power of the clergy and church courts, especially in taxation and appointments, and saw the Reformation as an opportunity to gain more control.

Question 60.
Who were some key leaders of the Reformation besides Martin Luther?
Answer:
Huldrych Zwingli and John Calvin in Switzerland and King Henry VIII in England played significant roles in the spread of the Reformation.

Question 61.
What was the Society of Jesus, and who founded it?
Answer:
The Society of Jesus (Jesuits) was a religious order founded by Ignatius Loyola

Question 62.
Write a note on the Counter-Reformation.
Answer:

• Following the Reformation, the Catholic Church initiated efforts to reform itself. This movement is known as the Counter-Reformation.
• Counter-Reformation is also known as Catholic Reformation.

As part of this initiative, the Church leadership convened the Council (Synod) of Trent in Northern Italy. The objectives of this council were to correct erroneous tendencies within the Church and to implement reforms. As a result, the sale of indulgences was banned. A list of books (The Index) that the believers should not read was published. The court of inquisition, which was there in Medieval times, was reinstituted.

The Society of Jesus, set up by Ignatius Loyola, a Spanish priest, also played a prominent part in Counter Reformation. Its members were bound to observe strict discipline and unquestioned obedience. They tried to establish the authority of the Catholic Church by setting up schools and engaging in active missionary work. Counter Reformation succeeded in eliminating a number of wrong tendencies in the Catholic Church. Counter-Reformation is also known as Catholic Reformation.

Question 5.
Discuss and make a note on the features of mercantilism.
Answer:

• Wealth is power – Countries believed that having more gold and silver made them stronger.
• More exports than imports – They tried to sell more goods to other countries and buy less to earn money.
• Colonies are useful – Countries took control of colonies to get raw materials and sell goods.
• Government control – The government-controlled trade and business to increase wealth.
• Strong navy and army – They built strong forces to protect trade and colonies.

Question 6.
‘It is the effective utilisation of wealth that helped in the industrialisation of England. Discuss and make a note on the topic.
Answer:
England did not just store its wealth – it used it wisely. The money was spent on building machines, factories, and better tools. This made work faster and easier. They also used money to improve transport, like building roads, canals, and railways, which helped carry raw materials and finished goods more easily. Wealth was also used to support new inventions and technology, which helped industries grow quickly. This smart use of money helped England start the Industrial Revolution, making it the first industrialised country in the world.

Question 7.
How does industrial capitalism differ from merchant capitalism? Make an explanatory note.
Answer:
Industrial capitalism is different from merchant capitalism. In merchant capitalism, merchants bought and sold goods made by others. They earned profit through trade and acted as a link between producers and consumers. In industrial capitalism, people used their money to build factories and buy machines to make goods. They earned more profit by producing and selling goods themselves.

So, the main difference is:

• Merchant capitalism is based on buying and selling.
• Industrial capitalism is based on making and selling goods using factories.

Question 8.
Conduct a debate on the topic merits and demerits of Industrial Revolution.
Answer:
• Team A – Merits (Good Sides) of the Industrial Revolution:
Better Machines and Factories: The Industrial Revolution brought machines and factories that made work faster and easier.
More Jobs: Many new jobs were created in cities for people in factories.
New Inventions: Many useful inventions like the steam engine, spinning jenny, and power loom were made.
Improved Transport: Trains, ships, and better roads made travel and transport of goods easier and faster.
Cheaper Goods: Goods were made faster and in large amounts, so they became cheaper to buy.

• Team B – Demerits (Bad Sides) of the Industrial Revolution:
Child Labour: Many children had to work in factories in bad conditions for long hours.
Pollution: Factories caused air and water pollution, which harmed people and the environment.
Unhealthy Living Conditions: Workers lived in crowded and dirty places in cities.
Loss of Jobs for Some People: Artisans and hand-workers lost jobs because machines replaced them.
Poor Working Conditions: Workers had to work for long hours with little pay and no safety.

Question 9.
Discuss how imperialism has transformed the economic policies of European countries.
Answer:
Imperialism changed the economic policies of European countries in many ways.
When European countries took control of colonies, they used the colonies to get raw materials like cotton, gold, and spices. They also used the colonies as markets to sell their goods. Because of this, European countries focused on:

• Taking resources from colonies
• Building factories in Europe using those resources
• Selling finished goods back to the colonies

This helped Europe become richer, but the colonies became poorer. So, imperialism made European economic policies mainly about profit from colonies.

Question 10.
Totalitarianism was a threat to civil liberties and world peace. Discuss and make notes.
Answer:
Totalitarianism is a form of government where one leader or one political party has total control over the country. In such a system, people are not allowed to speak freely or make their own choices. The government controls everything, including the media, education, and even what people are allowed to think or say. Civil liberties like freedom of speech, religion, and press are taken away. Totalitarian leaders often use fear, violence, and strict rules to stay in power. Leaders like Adolf Hitler in Germany and Benito Mussolini in Italy followed totalitarianism. They wanted to increase their power and even started wars to do so. This kind of rule not only caused suffering to the people but also became a big threat to world peace. It created tensions between countries and was one of the main reasons that led to the Second World War.

Question 11.
Compare and make notes on the reasons and the results of both world wars.
Answer:
Reasons

World war I	World War II
Countries were building up big armies and competing with each other.	Germany, Italy, and Japan wanted more power and land.
Many countries had secret agreements to help each other in war.	Germany, Italy, and Japan allied (Axis Powers).
Nations wanted more colonies and control over land.	Countries wanted to expand and take over weaker nations.
Countries didn’t trust each other and competed.	The war started when Germany invaded Poland.

Results

World war I	World War II
Countries were building up big armies and competing with each other.	About 70 – 85 million people died (much worse).
Many countries had secret agreements to help each other in war.	Hitler and fascist leaders lost power.
Nations wanted more colonies and control over land.	Germany was divided into East and West.
Countries didn’t trust each other and competed.	United Nations was created to help keep world peace.

Answer:
(Hints: based on the paragraph given below: conduct a digital presentation in the class)
Shaping Economies: Key Economic Policies (15th – 20th Century)

This digital exhibition explores how major economic policies have shaped global history. It began with mercantilism during European exploration, where wealth was built through trade and colonies. This led to the rise of colonial economies, which exploited native resources and labor. The Industrial Revolution followed, driven by capitalist policies like laissez-faire economics. In the 19th century, imperialism spread as powerful nations sought economic control over colonies. During World War I, war-time economies emerged, and the Treaty of Versailles caused economic turmoil. In the interwar years, totalitarian regimes used central planning to control economies. Finally, the post-war period brought recovery through the Marshall Plan, new global institutions, and mixed economies. Together, these policies reveal how economics influenced empires, wars, and modern nations.

Question 4.
Screen the movie Uncle Tom’s Cabin in the Social Science lab, which portrays theme of slavery and prepare an appreciation note.
Answer:
Uncle Tom’s Cabin, based on Harriet Beecher Stowe’s influential novel, offers a profound portrayal of the devastating impact of slavery in the United States. The film explores critical themes such as inhumanity, resilience, moral responsibility, and redemption. Through the character of Uncle Tom, viewers witness the strength and faith of an individual enduring unimaginable cruelty and his unwavering belief in dignity and compassion in the face of immense suffering. His sacrifice for others serves as a powerful symbol of hope, justice, and the ultimate cost of standing against oppression.

The film also emphasises the emotional toll of slavery, particularly the forced separation of families and the psychological trauma it caused. It reveals the profound human need for love, family, and connection, making the impact of slavery even more painful and relatable.

As much as Uncle Tom’s Cabin highlights the historical struggle for freedom and equality, it also serves as a timeless reminder of the ongoing fight for racial justice. The lessons of the past continue to resonate today, urging us to challenge systems of inequality and oppression actively. Watching this film is an opportunity not only to understand the historical context of slavery but also to reflect on how we can contribute to a more just, equal, and compassionate society.

In conclusion, the screening of Uncle Tom’s Cabin is more than just a historical reflection; it is a call to action for all of us to recognise the inherent value of every human life and to work together to ensure freedom and equality for all.

INTRODUCTION

This chapter, “Wealth and the World”, explains how Europe expanded its influence and built global wealth over time. It began with European expeditions to other continents in search of new trade routes, land, and resources. These voyages led to the rise of mercantilism, where European countries focused on increasing wealth through trade and colonisation. As they took over new lands, they exploited the resources and native populations, often with harmful consequences. This expansion and access to resources eventually contributed to the Industrial Revolution, which transformed economies with machines and factories. With growing power, European nations competed for more colonies, leading to imperialism. These rivalries, along with political tensions, triggered the First World War. After the war, the harsh Treaty of Versailles punished Germany and created unrest, leading to the rise of totalitarian regimes like fascism and Nazism. The chapter concludes by examining the post-war world, where global power dynamics shifted and new political ideas began to shape the future.

EUROPEAN EXPEDITIONS TO OTHER CONTINENTS

• After the Turks captured Constantinople, the primary trade route through which goods, including pepper from Asia, reached Europe was obstructed.
• As a result, Europeans began exploring new routes to access these valuable commodities and reached lands hitherto unknown to them.
• The arrival of the Portuguese sailors on the Guinea Coast marked another key milestone.
• These voyages and geographical explorations reshaped global history, leading to European domination and the gradual spread of European culture across the world.
• The early expeditions of Europeans were on the African continent.
• In 1488, the Portuguese sailor Bartolomeu Dias reached the Cape Hope located at the southern tip of Africa.
• A decade later, in 1498, Vasco da Gama followed the same route and successfully sailed around the eastern coast of Africa via the Cape of Good Hope.
• Two significant events in the 15th-century were instrumental in launching the geographical expeditions:
  • the conquest of Constantinople by the Turks
  • arrival of the Portuguese at the Guinea Coast in Africa

Portugal and Spain were the first to embark on expeditions that reshaped the world. Soon after, other nations like the Netherlands, England, and France joined in the exploration and conquest of new territories.

These countries are located along the Atlantic coast, a geographic advantage that greatly contributed to their involvement in global exploration. Several other factors also enabled these nations to undertake successful expeditions, which include:

• the building of advanced ships capable of crossing vast oceans
• the invention of the compass and other navigational tools for determining direction
• patronage of the rulers
• strong military power
• extensive experience in seafaring
• advances in cartography and astronomy

Knowledge of the gold deposits in the Niger plains motivated Portugal to embark on such ventures. The Portuguese initiated their conquest of Africa in 1415 by capturing Ceuta, a city on the Moroccan coast. This city later became a vital granary for them. One of the early challenges for Portuguese explorers was crossing Cape Bojador. However, after successfully navigating it in 1434, they gained access to other regions along the African coast. This breakthrough allowed them to profit significantly from the trade of gold and slaves, further encouraging their exploration efforts. In addition to Africa, the Portuguese expanded agriculture and established colonies on nearby islands in the Atlantic. In short, these ventures in Africa and the colonisation of Atlantic islands eventually paved the way for finding a sea route to Asia, marking a crucial milestone in global exploration.

Colonisation
Colonisation is a process by which a country establishes dominion in an alien country. The colonisers tried to exploit the colonies through economic, political and cultural domination.

In 1488, the Portuguese sailor Bartolomeu Dias reached the Cape of Good Hope, located at the southern tip of Africa. However, he was unable to navigate the rough sea route to India and was forced to return. Learning from this challenge, the Portuguese began building sturdier ships capable of withstanding the harsh conditions of the Indian Ocean. A decade later, in 1498, Vasco da Gama followed the same route and successfully sailed around the eastern coast of Africa via the Cape of Good Hope. He eventually reached the shores of Kappad in Kozhikode, India. This marked the beginning of European domination in India.

Spain was another country that took part in geographical expeditions. They too had long coast and the seafaring heritage just like the Portuguese. They received the patronage of King Ferdinand and Isabella the rulers of Spain. With the financial aid of Spain in 1492 Christopher Columbus, an Italian navigator, reached the Bahamas Islands located in the southeastern region of North America. This journey led to the discovery of a previously unknown continent for Europeans. The event paved the way for the invasion and exploitation of the region by Europeans, which came to be known as the “New World.” Eventually, this region was named America.

Atlantic Islands

The Atlantic Islands are located to the west of Africa in the Atlantic Ocean. Notable among them are Madeira, Azores, Canary and Cape Verde. These islands served as agricultural lands and strategic port centers. The Portuguese, who initially controlled many of these islands, used them as key bases for their operations in Africa and as stopover points for ships travelling to Asia to restock food and water. Later, the Canary Islands became a colony of Spain.

Prince Henry: Prince Henry of Portugal played a pivotal role in encouraging maritime exploration. In 1419, he established a navigation school in Sagres, Portugal, which trained sailors in the skills of sea voyages and cartography. Under his leadership, significant progress was made in the discovery of the Atlantic Islands and expeditions along the western coast of Africa.

Geographical explorations had far-reaching consequences. Let us examine some of them:

• The Atlantic coast emerged as the most important trade route, connecting Europe with the Americas, Asia, and Africa. This shift led to a decline in Mediterranean trade and the rise of Atlantic trade.
• Large parts of the Americas, Africa, and Asia came under European invasion and colonisation.
• Efforts were made by Europeans to monopolise the trade of pepper and other spices from Asia.
• Gold and silver were transported in large quantities from South America to Europe, with a portion of this wealth eventually reaching India.
• The development of the triangular trade system connecting Europe, Africa, and the Americas.
• The influx of gold and silver into Europe increased the use of currency, accelerating monetisation.

Over a period of time, the dominance in trade of Portugal and Spain declined, and countries like England, the Netherlands, and France took their place. In the competition among these nations, France and England surpassed the Netherlands and established colonies in Asia, Africa, and the Americas. The American regions once controlled by Spain and Portugal came to be known as Latin America. Subsequently, the world witnessed intense rivalry between England and France as they sought to maximise financial gains through colonisation.

Triangular trade

The products from Europe were sent to Africa, where Americas to be sold. From the Americas, goods such as sugar, wine, and cotton were then shipped to Europe. This system of trade, developed by Europeans, linking Europe, Africa, and the Americas, is known as the triangular trade.

How did the name “ America” come into being? …………
After Bartolomeu Dias, Christopher Columbus attempted to find a sea route to Asia. In 1492, he reached the Bahamas Islands near North America, mistakenly believing he had reached India. Later, an Italian explorer named Amerigo Vespucci realised that this was, in fact, a previously unknown continent, which he referred to as the “New World.” In 1507, a German cartographer named Martin Waldseemiiller named the region “America” in honor of Amerigo Vespucci.

MERCANTILISM

• Economic policy of European nations focused heavily on acquiring gold and silver, which were seen as symbols of wealth and power.
• According to mercantilist policy, the wealth of a nation was measured by the amount of gold and silver it possessed.
• A key characteristic of mercantilism was the effort to preserve a nation’s wealth (gold and silver) by reducing imports and increasing exports, thereby amassing wealth from other nations.

When Lord Vimioso learned that gold and silver had to be given to Indians in exchange for their goods, he felt that Europe was losing its precious resources and gave such a response. This highlights the concept of mercantilism, an economic policy where nations aimed to accumulate wealth, primarily gold and silver, through trade and other means. Countries that adopted this policy competed to accumulate wealth in the form of these precious metals.

COLONIAL POLICIES
• Colonial policies refer to the policies and strategies employed by colonial powers to extract wealth from their colonies.

The primary aim of the Portuguese colonial policy was to break the Asian spice trade monopoly of the Arabs and secure control over it. Under this policy, trade in the colonies became a monopoly of the Portuguese king. The Portuguese sought to keep other European powers out of this trade. As part of this effort, non-Portuguese individuals were prevented from travelling on Portuguese ships. Spain also governed its colonies directly under the authority of the king, focusing on extracting as much gold and silver as possible from the Americas to enrich the kingdom. In contrast, the Dutch and the English conducted their colonial trade through joint-stock companies. However, the Spanish and Portuguese kings directly controlled colonial trade. They used the wealth thus earned to build and renovate palaces. At the same time, companies like those in England and the Netherlands reinvested
their profits back into their businesses. This reinvestment substantially contributed to the growth of industries in England, playing a crucial role in its economic development.

Joint Stock Company: These are established by pooling capital from various sources, emphasising the importance of share investments. These companies facilitate investments by allowing individuals to contribute capital in shares

Bullion Coin
The silver and gold collected as wealth were known as Bullion. The value and amount of the metals in the coins were considered for the transactions. E.g., the value of the gold in a gold coin would be considered as its value in transaction.

COLONISATION AND NATIVES

• One of the consequences of European colonisation on native populations was slavery and the slave trade in Africa.
• Individuals who had been involved in trade before these explorations became very wealthy and were referred to as merchant capitalists. This economic system was known as Merchant Capitalism.
• The merchants acted as intermediaries between producers and consumers.
• Merchant capitalism gave way to industrial capitalism.

Factors that affected colonisation include:

• Wealth was extracted from the colonies and flowed into European countries
• natives lost their economic and political rights over their own regions
• indigenous cultures in the colonies faced destruction
• Western lifestyles and practices spread across the colonies
• Christianity was propagated in colonised regions

NEW WORLD, CHANGING ECONOMIC ORDERS
In this system, merchants supplied raw materials to artisans living in rural areas. The artisans manufactured goods in cottage-based production. After compensating the artisans for their labour, the merchants sold the finished products and made profits. These merchants acted as intermediaries between producers and consumers. England started industries using the wealth gained through eolonisation. Those who invested their wealth in this way became the owners of industries and made huge profits. With this, merchant capitalism gave way to industrial capitalism.

MOVING TOWARDS THE INDUSTRIAL REVOLUTION

• The introduction of machinery into the manufacturing sector brought about many changes.
• Such changes in the production process between 1780 and 1850 describe the Industrial Revolution.
• The Industrial Revolution began in the textile industry.
• The term ‘Agrarian Revolution’ is used to refer to the series of changes that took place in England’s agricultural sector in the 17^th century.

Let us examine the major changes that took place as part of the Industrial Revolution.

• production was mechanised
• advancement in metallurgy leading to the production of better tools
• Steam was used as a source of energy
• transport facilities developed
• Production shifted from cottages to factories

Agrarian Revolution
The term ‘Agrarian Revolution’ is used to refer to the series of changes that took place in England’s agricultural sector in the 17th century. Major changes associated with the Agrarian Revolution:

• Small farms were consolidated to form large farms protected by fencing (Enclosure Movement)
• Crop rotation was introduced
• Use of new agricultural implements.
  As a result, there was an increase in food production.

The Industrial Revolution paved the way for both positive and negative changes:

Merits	Demerits
Rise of factories	Exploitation of labourers
Increase in production	Poverty, epidemics
New employment opportunities	Long working hours and low wages for women and children
Rise of cities and urbanisation	Rise of slums
Urban life	Busy and polluted cities
Better living conditions	Miserable life for labourers in cities

In response to industrial capitalist exploitation, various forms of resistance and ideologies emerged, with socialism being ‘one of the most significant. The core principles of socialist ideologies were the equitable distribution of goods and resources, and the common ownership of the means of production. Karl Marx and Friedrich Engels played a pivotal role in transforming socialism from an early-stage dream or belief into a practical and scientific ideology.

IMPERIALISM

• As factory production increased, industrialised countries found it difficult to source raw materials exclusively from within their own borders.
• Industrial capitalists sought to maximise profits by increasing production while minimising wages.
• Imperialism is the practice by which a country establishes and maintains political, economic, and social control over regions beyond its own borders.

Imperialism
Imperialism is the practice by which a country establishes and maintains political, economic, and social control over regions beyond its own borders.

This cartoon, (Rubber coils in the Belgian Congo) published in 1906 in the British satirical magazine Punch, depicts King Leopold of Belgium as a snake constricting a native of Congo. It highlights the devastating impact of Belgium’s rubber plantations on the people of Congo, an African country.

As factory production increased, industrialised countries found it difficult to source raw materials exclusively from within their own borders. As a result, countries like Belgium turned to their colonies, such as Congo, to obtain raw materials like rubber. However, reducing wages decreased the purchasing power of workers, making it harder to sell goods domestically. This led industrialised nations to seek markets abroad. Colonies became both a source of raw materials and a market for European manufactured goods. To secure this arrangement, European countries established political control over their colonies, which paved the way for imperialism.

By the latter half of the 19th century, countries like England and France became dominant imperial powers. These two countries controlled a major portion of the world. Soon, Germany, Italy, Belgium, the USA and Japan also emerged as new imperial nations. The new imperial nations made attempts to expand their colonies in various parts of the world. This led to the competition between the new and old imperial nations. This influenced the course of history in the 20th century and paved way for new conflicts.

FIRST WORLD WAR

• First world war, which lasted from 1914 to 1918.
• It was the first global war in which nearly every country participated, either directly or indirectly.
• The Pan-Slav Movement advocated for the unification of regions in Eastern Europe inhabited by Slavic people. Serbia, a Balkan nation, led this movement, and Russia supported this.
• The Pan-German Movement, led by Germany, aimed to unite the Teutonic (Germanic) people. The goal of this movement was to expand German influence into Central Europe and the Balkan region.

IMPERIALIST RIVALRY
The new imperialist nations could expand their influence only by capturing territories controlled by the older imperialist powers. Germany’s unprecedented progress in economic and industrial sectors caused concern for France and England. With much of Asia and Africa already under British and French control, Germany turned its focus towards regions under the Ottoman Empire. To achieve this, they planned the construction of the Berlin-Baghdad railway line. This project alarmed England, France, and Russia, as they feared it could threaten the security of their territories. Consequently, tensions and hostilities began to escalate among these nations.

EXTREME NATIONALISM

• Extreme nationalism refers to an intense and emotional devotion to one’s country, often involving its excessive glorification.
• This concept is often related to racism.

Many nations argued that regions inhabited by a particular race rightfully belong to that race alone. Such arguments were used by many nations to justify territorial expansion and conquest. In countries like Germany and Serbia, extreme nationalism grew in alarming proportions. Movements such as Pan-Slavism and Pan- Germanism serve as examples of organisations promoting such extreme nationalist ideologies.

Pan-Slav Movement
The Pan-Slav Movement advocated for the unification of regions in Eastern Europe inhabited by Slavic people. Serbia, a Balkan nation, led this movement and Russia supported this.

Pan-German Movement
The Pan-German Movement, led by Germany, aimed to unite the Teutonic (Germanic) people. The goal of this movement was to expand German influence into Central Europe and the Balkan region.

FORMATION OF MILITARY ALLIANCES

• The competition for colonies and the rise of extreme nationalism created fear and mistrust among European nations. This atmosphere of suspicion led to the formation of military alliances.
• Two military alliances: Triple Alliance, Triple Entente.
• Sarajevo, the capital of Bosnia, was the site of a significant event that further fuelled tensions.

Conflicts arose across various parts of the world between countries belonging to the two major alliances. These conflicts often stemmed from attempts to seize colonies held by rival nations. The situation escalated as allied nations joined forces with their respective allies, intensifying the clashes.

Sarajevo, the capital of Bosnia, was the site of a significant event that further fuelled tensions. Archduke Franz Ferdinand, the Crown Prince of Austria-Hungary, was assassinated in Sarajevo, where former French president Mitterrand visited. The assassin, Gavrilo Princip, was a Serbian nationalist. Due to the existing conflict between Serbia and Austria-Hungary, Austria accused Serbia of orchestrating the assassination. This led Austria- Hungary to declare war against on Serbia on July 28, 1914. As allied nations aligned themselves with their respective sides, the conflict expanded into a World War.

Aftermath of the First World War:

• Millions of soldiers and civilians lost their lives
• Industrial and agricultural sectors were devastated
• marked the beginning of the decline of European global domination
• Freedom movements in Asia and Africa gained momentum.
• Formation of the League of Nations
• Italy, Germany, and Spain transitioned to totalitarian regimes

League of Nations
Woodrow Wilson, the American President, proposed the idea of forming an international organisation to maintain world peace and ensure freedom for all nations. Based on this proposal, the League of Nations was established on January 10,1920, to restore global peace and security.

THE GROWTH OF TOTALITARIANISM IN EUROPE

• Totalitarianism refers to a system where the state exerts complete control over all aspects of life, disregarding individual privacy and civil rights.
• This ideology glorifies the state above all else, forcing citizens to live solely for their nation.
• The term “Fascism” is derived from the Latin word ‘fasces, which refers to a bundle of rods and an ‘Axe’ symbolising authority and power, a representation of the rule of Roman emperors.

Key features of totalitarianism:

• rejection of democracy
• opposition to socialism’
• supporting dictatorship
• extreme nationalism
• elimination of political opponents
• glorification of war and violence

Fascism
The term “Fascism” is derived from the Latin word ‘fasces’, which refers to ‘a bundle of rods and an ‘Axe’ symbolising authority and power, a representation of the rule of Roman emperors.

Totalitarian movements that came to power in Italy and Germany after the World War:

TREATY OF VERSAILLES

• The background of the second world war took place from 1939 to 1945.
• World War II begins with Germany’s invasion of Poland on September 1, 1939.
• The Treaty of Versailles was a peace treaty that Germany signed with the Allies after World War I.
• Germany was disarmed and huge war reparations were imposed on Germany.
• Imperialist rivalry led to the formation of the military alliances.

TREATY OF VERSAILLES
The Treaty of Versailles was a peace treaty that Germany signed with the Allies after World War I. Its provisions sowed the seeds of World War II. Under this treaty, Germany lost its colonies and territories it held. Germany was disarmed and huge war reparations were imposed on Germany. In short, World War II was a German revolt against the Treaty of Versailles and its architects.

The Failure of League of Nations:
The League of Nations formed after World War I was unable to resolve disputes or enforce international disarmament. The league failed to act when Japan, Italy, and Germany launched offensives.

FORMATION OF MILITARY ALLIANCES
Imperialist rivalry led to the formation of the following military alliances.

Later Soviet Union and USA became part of the allied powers

Munich agreement
Hitler laid claim to the Sudetenland, the most industrialised region of Czechoslovakia. Hitler’s argument was based on the large German population living in Czechoslovakia. Instead of resisting Hitler’s argument, France and Britain ceded the Sudetenland to Germany in a treaty signed in Munich, Germany in 1938. This is called the Munich Agreement. This treaty was not ratified by Czechoslovakia. The Soviet Union, which supported them, was not invited to the talks.

POLICY OF APPEASEMENT

• The Soviet Union, which came into being after the Russian Revolution, spread socialist ideas around the world.
• The Munich Agreement is a prime example of Western appeasement.

The Soviet Union, which came into being after the Russian Revolution, spread socialist ideas around the world. This was a threat to other western capitalist countries. For this reason, they saw the Soviet Union as their enemy. They saw fascist aggression as a means of countering the spread of socialist ideas. The Munich Agreement is a prime example of Western appeasement. These appeasement policies gave Hitler confidence and he continued his offensives aggressively. World War II begins with Germany’s invasion of Poland on September 1,1939.

Results of the war:

• Millions lost their lives
• Famines and epidemics spread throughout the world
• The European economy collapsed
• Colonisation and imperialism faced setbacks
• Europe’s hegemony came to an end
• The United Nations Organization was formed
• Totalitarianism ended in Italy and Germany
• Colonies in Asia and Africa gained independence
• The United States and the Soviet Union emerged as global powers

United Nations Organisation
After the Second World War, the United Nations Organisation was formed with the aim of ensuring global peace and security. It was established on October 24,1945.

POST WAR WORLD

• It was economic interests that caused the imperial rivalry of the European powers and led the two world wars.
• The United States and the Soviet Union followed contrasting economic policies.
• Cold war ended in 1991 with the disintegration of the Soviet Union.
• The Cold War was an ideological confrontation between the capitalist countries and the socialist countries.
• Finance capitalism is an economy in which financial institutions such as banking and insurance play a major role.
• Finance Capitalism works with the aim of making huge profits.

By the end of World War II, the European powers that had fought each other had become irrelevant. The United States and the Soviet Union followed contrasting economic policies. While the United States adopted capitalist policies and the Soviet Union opted for socialist policies. Both countries were wary of each other and tried to spread their ideas throughout the world. This cold war between them lasted for about half a century. Cold war ended in 1991 with the disintegration of the Soviet Union.

Cold War
The Cold War was an ideological confrontation between the capitalist countries after the Second World War. This was not a time of apparent war or peace. The Non-Aligned Movement is a coalition of countries that did not belong in either of these camps.

The colonies, in Asia and Africa gained independence after second world war. With this, America followed capitalist ideas and adopted new ways to gain wealth. The USA funded the newly independent countries, which was a form of exploitation. This was a different kind of colonisation. This policy is known as Neo Colonialism. This new colonial policy was implemented through finance capitalism.

FINANCE CAPITALISM

• Financial exchanges are more important at this stage than industrial production and population welfare.
• Banks, stock market and investment institutions play a crucial role in this economy.
• This system allows for the accumulation of more wealth without any production or technological change.

Finance capitalism allows big corporates to exert influence beyond military power and war. Such companies invest in different countries and make profits. Finance Capitalism works with the aim of making huge profits. Common people and those involved in traditional occupations continued to suffer the consequences. They lose the resources they could have used freely and are controlled by capitalists. Uncontrolled exploitation of resources also leads to environmental problems.

New technologies and related changes in society have led to the emergence of these economic changes. Capitalism developed through several stages over five centuries. It highlights the role of economic factors and systems in determining the course of history. Along with this, this period also witnessed the collapse of human values before capitalist interests.

Class 10 History Chapter 1 Notes Kerala Syllabus Humanism

Question 1.
Evaluate the significance of the statement that the Renaissance was a period of transition from the medieval to the modern.
Answer:
From the 14^th century onward, a series of changes took place in the social, economic, and political spheres of Europe. Along with the influence of the Greco-Roman cultures of ancient Europe, a tendency to move away from the ideas that existed in the medieval times also gained strength. These changes were particularly evident in Italy, which was part of the ancient Roman civilisation. Historians termed these changes the ‘Renaissance.’ The Renaissance is considered as a period of transformation from the medieval feudalism to the modern age. The word “Renaissance” means “rebirth.” It denotes the revival of ancient Greco-Roman culture, which began around the 14^th century. During the Middle Ages, people focused mainly on religion and followed traditional beliefs. But in the Renaissance, there was a revival of art, science, and learning. People started questioning old ideas, exploring discoveries, and emphasising human potential.

Question 2.
Observe the map given below. Identify the cities that existed in medieval Italy.

Answer:

1. Florence
2. Milan
3. Geona
4. Pisa
5. Venice
6. Parma
7. Naples
8. Rome

Question 3.
Italian cities were wealthier compared to other European cities. Describe the circumstances that led to this.
Answer:

• They were more independent, wealthy and dynamic.
• Traders in these cities were well aware of banking and insurance. Some of them had expertise in technical matters of trade, such as bookkeeping.
• Many of them had become extremely wealthy through trade.
• Italian cities got acquainted with the cultures, cities, and lives of the people in the Eastern world. This accelerated the growth of Italian cities. As a result of trade links with the Islamic Empire and the Byzantine empire, enormous wealth flowed into the Italian Cities.
• Merchants in Italian cities gained a monopoly in the trade between the East and West in the Mediterranean.

Question 4.
Discuss the impact brought about by the outbreak of the plague in 14^th century in various fields in Europe.
Answer:
The Bubonic Plague, which erupted in the mid-14^th century, several affected the Italian cities. This catastrophic event, known as the ‘Black Death,’ claimed the lives of thousands, resulting in a severe shortage in labour. This paved the way for the decline of medieval feudalism, which was heavily reliant on the agricultural sector. Furthermore, it facilitated the emergence of a new commercial middle class. When traditional medicines failed to fight the plague, people began to explore the medical sciences of ancient Greece and Rome. The terrors of the plague prompted human beings to contemplate the fleeting nature of life, seek wellness, and focus on their well-being. This introspection paved the way for the emergence of humanism.

Question 5.
Locate Constantinople on the map. Discuss its geographical significance.
Answer:

Constantinople (now Istanbul, Turkey) is located between Europe and Asia, on the Bosporus Strait. Its geographical significance comes from its position as a bridge between the two continents, making it a key center for trade and culture. It controlled major trade routes between Europe, Asia, and the Middle East, helping it grows into a powerful and wealthy city. Its location also made it a strong defensive city, protected by water on three sides.

Question 6.
Assess the impact of the conquest of Constantinople by the Turks on the intellectual landscape of Italy.
Answer:
In 1453, the Ottoman Turks conquered Constantinople, the capital of the Eastern Roman Empire. This city was a center of many scholars who possessed manuscripts of ancient Greco-Roman literary works. In the aftermath of the Turkish conquest, these scholars migrated to Italian cities, bringing their manuscripts with them. As a result, research and studies, previously confined to universities during the Middle Ages, began to spread to libraries. The convergence of wealth and political freedom created a fertile ground for artistic innovation and cultural experimentation. Consequently, novel ideas began to emerge in the cultural and intellectual spheres.

Question 7.
How did the emergence of humanism impact the course of world.
Answer:
The emergence of humanism brought a significant change in the way people thought about life, knowledge, and society. Before humanism, most knowledge was controlled by the Church, but humanist ideas encouraged people to think logically and question existing beliefs. This led to the growth of education, with more focus on subjects like history, literature, science, and philosophy, resulting in the rise of universities and schools. Humanism also influenced art and literature, inspiring famous artists like Leonardo da Vinci and Michelangelo to create realistic works, while writers like Shakespeare and Dante focused on human emotions and experiences. In science, humanist thinking helped scientists like Galileo and Copernicus make groundbreaking discoveries, leading to the Scientific Revolution. Additionally, humanism promoted ideas of democracy, freedom, and human rights, which later influenced governments where people had more say. The curiosity sparked by humanism also led to the Age of Exploration, where explorers like Columbus and Vasco da Gama discovered new lands, connecting different parts of the world. Overall, humanism played a crucial role in shaping the modern world by encouraging education, innovation, and individual rights.

Question 8.
Look at the pictures given here and identify the characteristic features of Renaissance paintings reflected in them.


This is a depiction of “ Agony in the Garden” by Giovanni Bellini, a renowned Italian Renaissance painter. The scene illustrates Jesus Christ kneeling in prayer on the Mount of Olives while his disciples sleep nearby. In the background, a group of Roman soldiers can be seen approaching to apprehend Jesus Christ.

This is the renowned diptych oil painting by the Italian Renaissance painter Piero della Francesca, titled “Diptych of Federico da Montefeltro and Battista Sforza.”
Answer:
The paintings reflect key features of Renaissance art. One important feature is realism, as the people in the paintings look natural with detailed facial features, clothing, and backgrounds. Another feature is perspective, which creates a sense of depth, making the background appear far away instead of flat. Renaissance art also focused on human emotions and individuality, showing expressions and feelings rather than stiff, lifeless figures. The use of light and shadow (chiaroscuro) adds depth and makes the figures appear more three-dimensional. Additionally, Renaissance artists were inspired by Greek and Roman art, which can be seen in the balanced composition and realistic human forms. The paintings also show a mix of religious and secular themes, as one painting depicts a biblical scene while the other features real historical figures. These elements together make Renaissance art more lifelike, expressive, and advanced compared to medieval paintings.

Conclusion: Humanism transformed art, making it realistic, expressive, and innovative.
Quote: “A man paints with his brain, not with his hands”. – Michelangelo.

Question 12.
“Every prince ought to desire to earn the reputation of being merciful, and not be cruel; at the same time, he should also be careful that no one else misuses that mercy. A prince, therefore, should not care for the ill repute of being cruel while ensuring solidarity and loyalty among the subjects.” Machiavelli’s perspective about a king is given above. Based on this, discuss the ideas put forward by Machiavelli about monarchy. Examine to what extent humanism is reflected in this.
Answer:
Machiavelli’s Ideas on Monarchy and Humanism
Machiavelli believed a ruler should be strong and practical rather than overly kind. In The Prince, he argued that:

• Power & Control: A king must ensure stability.
• Fear vs. Love: Being feared is better than being loved.
• Practicality Over Morality: A ruler should act based on reality, not just ideals.
• Avoiding Weakness: Too much mercy can lead to disorder.

Humanism in Machiavelli’s Ideas:

• Focused on human intelligence and reason, not religious rules.
• Encouraged rulers to use strategy and real-world experience over morality.
• His ideas reflect humanism by emphasising logic, leadership, and human decision-making over divine authority.

Question 13.
Prepare an essay on the topic ‘Humanism and Renaissance Literature’.
Answer:
Humanism and Renaissance Literature
The Renaissance (14^th – 17^th century) brought a shift in literature through humanism, which focused on human potential, emotions, and real-life experiences.
How Humanism Influenced Renaissance Literature:
Use of Vernacular Languages: Writers used local languages instead of Latin. (Example: Dante’s Divine Comedy)
Focus on Human Emotions & Individuality: Literature explored personal struggles and feelings. (Example: Shakespeare’s Romeo and Juliet)
Realistic Characters & Stories: Writers portrayed human strengths and weaknesses.
Political & Social Ideas: Some works discussed leadership and power. (Example: Machiavelli’s The Prince)
Printing Press Impact: Helped spread knowledge and books to more people.
Conclusion: Humanism made literature more realistic, emotional, and people-centered, shaping modern storytelling and ideas.

Question 14.
Elucidate the role of Renaissance in making historiography scientific.
Answer:
The Renaissance made historiography more scientific by introducing a rational and evidence-based
approach. Historians Flavio Biondo and Leonardo Bruni classified history into Ancient, Medieval, and Modem periods, marking a shift from religious narratives to structured analysis. The transition from theological to human-centred explanations replaced divine interpretations with a focus on human actions. Archaeological evidence, inscriptions, and manuscripts gained importance, emphasising factual accuracy. Humanism promoted critical thinking, replacing myths with logical inquiry. Thinkers like Machiavelli applied analytical methods, making history more systematic, secular, and evidence-driven. This transformation laid the foundation for modem historiography.

Question 15.

Student 4: Leonardo da Vinci designed early flying machines and studied anatomy, inspiring modem inventions.
Moderator: The Renaissance helped in astronomy, medicine, physics, and engineering, shaping the world today. Thank you!

Question 16.
The influence of humanism became the reason for Reformation; justify this statement.
Answer:
Humanism played a big role in the Reformation because it encouraged people to think critically and question traditional beliefs. Humanist scholars like Erasmus wrote satirical works that criticised the Catholic Church’s practices. Other reformers, such as John Wycliffe, Jan Hus, and Savonarola, also pointed out problems in the Church, especially the sale of indulgences. The Renaissance focus on education and individual thinking led Martin Luther to challenge the Church by writing his Ninety-Five Theses. Although he initially wanted only a debate, his ideas spread quickly, leading to the Protestant Reformation. Additionally, many rulers supported the Reformation because they wanted to reduce the Church’s power over taxation and appointments. Leaders like Zwingli, Calvin, and Henry VIII helped establish new branches of Christianity, further spreading the Reformation. Overall, humanism encouraged people to think for themselves, leading them to question and eventually reform the Church.

Question 17.
Compare and contrast reformation and counter-reformation.
Answer:

Aspect	Reformation	Counter-Reformation
Reason	Started to protest against some practices in the Catholic Church.	Reform movement within the catholic church.
Leaders	Martin Luther, John Calvin, Huldrych Zwingli, King Henry VIII.	Catholic Church leaders, including the Pope and Ignatius Loyola.

INTRODUCTION

The Renaissance was a period of cultural, artistic, and intellectual rebirth that revived Greco-Roman ideas and bridged the gap between the Middle Ages and modem times. Rooted in humanism, it emphasised human potential, creativity, and reason, shifting focus from religious authority to individual achievement. Emerging in Italy, it spread across Europe, influencing art, literature, science, and historiography. Great thinkers like Leonardo da Vinci, Michelangelo, Shakespeare, Copernicus, and Galileo reshaped their fields. The Reformation, influenced by Renaissance ideas, led to major religious reforms. This chapter, ‘Humanism,’ explores the Renaissance’s impact on humanism, art, literature, science, historiography, and religion, shaping the world as we know it today.

Renaissance and Historiography

• The classification divides history into three distinct periods:
• the Ancient Period, spanning up to the 5th century CE;
• the Medieval Period, extending from the 5th to the 15th century;
• and the Modern Period, encompassing the era thereafter.
• This classification emerged during the Renaissance period. It was introduced by two Italian historians, Flavio Biondo and Leonardo Bruni.

• The influence of the Renaissance extended to the realm of religion also in Europe.
• The universities of Germany, particularly Wittenberg University, where Martin Luther taught, played an important role in laying the groundwork for the Reformation.
• The Reformation, which originated in Germany, soon spread to other European kingdoms.

RENAISSANCE

• The word “Renaissance” means “rebirth.” It denotes the revival of ancient Greco-Roman culture, which began around the 14^th century.
• The Renaissance is considered as a period of transformation from the medieval feudalism to the modern age.
• The two most important civilisations that existed in ancient Europe were Greek and Roman civilisations.

They are known as classical civilisations From the 14^th century onwards, a series of changes took place in the social, economic, and political spheres of Europe. Along with the influence of the Greco-Roman cultures of ancient Europe, a tendency to move away from the ideas that existed in the medieval times also gained strength.

Characteristic features of these changes:

• Humanistic Perspective (Humanism)
• Growth of urban life
• Progress of trade
• Rise of national state
• Individual liberty
• Rationalism
• Spread of secular values
• Monetary economy
• Importance gained by regional languages
• Changes in the realms of art and science

Greco-Roman Civilisations
The two most important civilisations that existed in ancient Europe were the Greek and Roman civilisations. They are known as classical civilisations. The Greek civilisation was from 12^th to 4^th century BCE. The Roman civilisation existed from the 7^th century BCE to the 5^th century CE.

These changes were particularly evident in Italy, which was part of the ancient Roman civilisation. Historians termed these changes the ’Renaissance.’ The Renaissance is considered as a period of transformation from the medieval feudalism to the modern age. The word “Renaissance” means “rebirth.” It denotes the revival of ancient Greco-Roman culture, which began around the 14^th century.

RENAISSANCE IN ITALY

• The commercialisation that occurred in Europe by the 11^th century led to the disintegration of the medieval feudal system and the decline of religious supremacy.
• Several wealthy families also emerged in Italy.
• The Crusades that took place during the medieval period facilitated cultural exchange between the East and the West.
• The Bubonic Plague, which erupted in the mid-14th century, several affected the Italian cities. This catastrophic event, known as the ‘Black Death’.
• The prosperity, political liberty, and social unity of the cities fostered civic sense and self-respect among people.

Florence, Pisa, Naples, Milan, Parma, etc., were the major cities in medieval Italy. Cities in Italy were different from the rest in Europe. The reasons is that:

• They were more independent, wealthy and dynamic.
• Traders in these cities were well aware of banking and insurance. Some of them had expertise in technical matters of trade, such as bookkeeping.
• Many of them had become extremely wealthy through trade.

The commercialisation that occurred in Europe by the 11th century led to the disintegration of the medieval feudal system and the decline of religious supremacy. This led to the emergence and domination of the new wealthy class. As a result, several wealthy families also emerged in Italy.

Bookkeeping
Detailed recording of the income and expenditure of an establishment on a daily basis ¡s called bookkeeping. Bookkeeping is the first step in accounting.

The Crusades that took place during the medieval period facilitated cultural exchange between the East and the West. Italian cities got acquainted with the cultures, cities, and liv es of the people in the Eastern world. This accelerated the growth of Italian cities. Merchants in Italian cities gained a monopoly in the trade between the East and West in the Mediterranean.

The Crusades: The wars fought between believers of Islam and Christianity over Jerusalem, which was considered a holy land by both, are known as Crusades. The crusades that took place from the 11th to 13th century had a profound impact on the political, social and economic lives in both Europe and Asia.

The Bubonic Plague, which erupted in the mid-14th century, several affected the Italian cities. This catastrophic event, known as the ‘Black Death,’ claimed the lives of thousands, resulting in a severe shortage in labour.

Black Death
The Black Death is the epidemic that ravaged Europe between 1347 and 1351. Black boils appeared on those who were affected by the disease. That is why the disease is known as Black Death. This epidemic spread through the fleas carried by rats that reached European ports via merchant ships.

• This paved the way for the decline of medieval feudalism, which was heavily reliant on the agricultural sector. Furthermore, it facilitated the emergence of a new commercial middle class.
• When traditional medicines failed to fight the plague, people began to explore the medical sciences of ancient Greece and Rome. The terrors of the plague prompted human beings to contemplate the fleeting nature of life, seek wellness, and focus on their own well-being. This introspection paved the way for the emergence of humanism.

Revived interest in the concepts of law and order and governance that had flourished in the ancient Roman Empire began to spread throughout Italy. A section of the population well-versed in ancient Roman law and the Latin language turned their attention to commercial pursuits. This, in turn, sparked a renewed interest in classical languages, literature, institutions and antiquity. Each city aspired to become a centre of art and literature. Under the patronage of rulers and clergy, people sought out, collected, and preserved the remnants of ancient Rome, including paintings, manuscripts, and architectural remains. The rulers realised that, rather than waging wars, commissioning grand buildings and fostering art and literature would be a better way to leave a lasting legacy in the minds of the people.

• Wealthy patrons beautified their parish churches and actively promoted the construction of monasteries and nunneries as well as cathedrals.
• In Italian cities such as Florence, Milan, Rome, and Venice, patronage of the arts was considered a civic responsibility.

In 1453, the Ottoman Turks conquered Constantinople, the capital of the Eastern Roman Empire. This city was a centre of many scholars who possessed manuscripts of ancient Greco-Roman literary works. In the aftermath of the Turkish conquest, these scholars migrated to Italian cities, bringing their manuscripts with them. As a result, research and studies, previously confined to universities during the Middle Ages, began to spread to libraries. The convergence of wealth and political freedom created a fertile ground for artistic innovation and cultural experimentation. Consequently, novel ideas began to emerge in the cultural and intellectual spheres.

A Colonial Perspective of European Renaissance: Several arguments have emerged of late challenging the conventional view that the Renaissance originated in Europe. Works like Stolen Legacy by George James, Black Athena: The Afroasiatic Roots of Classical Civilisation by Martin Bernal present alternative perspectives. They are of the view that colonial historians have perpetuated a Eurocentric narrative, portraying Europe as the sole hub of civilisation. They dismissed the contributions of other cultures. According to these critics, this biased approach has led to the marginalisation of non-European cultures, implying that only Europeans are civilised while others are uncivilised.

HUMAN BEINGS AT THE CENTRE

• The Middle Ages were predominantly influenced by the philosophical school of thought known as scholasticism, which was deeply rooted in Christian theology.
• Humanists highlighted the uniqueness, emotions, capabilities, literary expression, and communication skills inherent in humanity.
• The Arabs played a significant role in disseminating the ideas of the ancient Greek philosopher Aristotle throughout Europe.
• Humanists produced works in regional languages and created paintings and sculptures in the Greco- Roman style.
• Humanism later became a source and inspiration for transformative changes across various spheres, including painting, architecture, literature, politics, history, science, and religion.

Scholasticism encouraged knowledge and research, and it prioritised the divine and the afterlife. The concept of Humanism emerged as a departure from Christian theology, emphasising the significance of human experience, worldly life and rational inquiry. Humanists highlighted the uniqueness, emotions, capabilities, literary expression, and communication skills inherent in humanity. This paradigm shift was founded on a transformation from a theological perspective to a human-centered outlook. Humanism also accommodated dissenting voices and criticism, questioning the authority of religious dogma and domination.

During this period, people avidly read ancient Greco-Roman works. Ancient Greco-Roman civilisations served as their primary source of inspiration, and the humanists’ perspective was distinctly different. Greco- Roman art depicted Gods, the wealthy, and the powerful in all their beauty and splendour. However, Renaissance art represented human beings in all their naturalness. The numerous works of art and literature produced during the Renaissance period bear testimony to this shift. Humanism later became a source and inspiration for transformative changes across various spheres, including painting, architecture, literature, politics, history, science, and religion. The Renaissance, in essence, embodies these changes.

Aristotle was a philosopher who lived in ancient Greece. His ideas paved the background for new questions and debates in the Renaissance period. His works, translated into Latin and regional languages in the 12^th and 13^th centuries, were widely disseminated throughout Europe. The significance Aristotle placed on the pursuit of truth, coupled with the profound depth of his scholarly endeavors, accounted for the immense interest in his ideas.

RENAISSANCE ART

• Middle age paintings tend to emphasise spiritual themes, such as angels and heavenly realms, whereas Renaissance paintings focus on the beauty of the human form, originality and a naturalistic use of colours.
• Humanistic ideals were refected profoundly in Renaissance paintings. Painters of the time presented human forms with remarkable accuracy, clarity, and meticulous attention to detail in their works.
• Sculpture was another equally notable field of Renaissance art. Donatello was one of the most important sculptors of the Renaissance period.
• Architecture was another field that witnessed transformation besides painting and sculpture. Filippo Brunelleschi set a new style in architecture.

The shift in artistic focus was a hallmark of the Renaissance period, during which fields like painting, sculpture, and architecture underwent profound transformations. Florence, one of the major commercial centres in Europe, was also the centre of Renaissance in Italy.

PAINTING

• Humanistic ideals were reflected profoundly in Renaissance paintings. Painters of the time presented human forms with remarkable accuracy, clarity, and meticulous attention to detail in their works.
• The knowledge they had acquired about human anatomy facilitated this artistic achievement.

Moreover, painters emphasised rationalism and human emotions, attributing significance to the values of this world. With the influence of humanism, artworks became increasingly precise and realistic. Painters often selected themes that emphasised theological significance for their works. However, Renaissance paintings had certain other distinctive features as well:

• Landscapes
• The use of colour to illustrate light and spatial depth
• Realistic depiction of the human body
• The use of oil paint
• Portraits
• The representation of divine figures in idealised human forms

The influence of Greco-Roman art was’ first evident in Giotto’s works. However, it was Masaccio, a painter who emerged later created a profound impact on all artists who came later. His wall paintings, characterised by their round shape and seeming to protrude from the surface, showcased human figures. Engaging in everyday life experiences. The Last Supper and Mona Lisa are world-famous paintings by Leonardo da Vinci. These paintings speak of the unique way in which da Vinci harmonises colour, shadow and light. He was a versatile genius who scientifically studied the human body.

• In the ‘Last Supper,’ emotions like surprise, fear and guilt of Christ’s disciples are vividly etched as Christ reveals that one of them betrayed him. It is widely acknow ledged that the enigmatic expressions of the Mona Lisa conceal many unanswered questions masterfully embedded by Leonardo da Vinci.
• The paintings done on the ceiling of the Sistine Chapel at the Vatican, along with The Last Judgment, have cemented Michelangelo’s status as an immortal artist. His works predominantly feature powerful and graceful human forms.
• Other notable painters of the Renaissance period include Titian and Raphael. Raphael portrayed humans as wise, moderate, and dignified. In their paintings, beauty and ideas were given equal importance.

SCULPTURE
Sculpture was another equally notable field of Renaissance art. Donatello was one of the most important sculptors of the Renaissance period.

He liberated the art of sculpture from the medieval Gothic style, giving his works greater power and individuality. His iconic bronze sculpture, David, showcases a youthful figure standing with his weight shifted onto one leg. Another notable work, ‘Gattamelata’, depicts a soldier sitting on horseback, evoking the cavalrymen of ancient Rome. Through this masterpiece, Donatello immortalised a secular hero.

Michelangelo’s sculptures, which depicted Gods in human forms, deviated significantly from the traditional ancient Greco-Roman style. His renowned works, such as the ‘Pieta’, which portrays the Virgin Mary with Jesus Christ on her lap and the majestic sculpture of ‘David’, have cemented his legacy as an immortal artist.

ARCHITECTURE
Architecture was another field that witnessed transformation besides painting and sculpture. Filippo Brunelleschi set a new style in architecture.

Quite different from the Gothic architectural style of the medieval period, the influence of ancient Greco-Roman (classical) style is evident in the Cathedral he built in Florence. The lofty towers found in Gothic style were replaced with domes (Dumo). Later, in the St. Peter’s Basilica, built under the supervision of Michelangelo and Bramante, this style is more evident.

Gothic style
Gothic style developed in Europe in the second half of the Middle Ages. It originated in France. The pointed arch was its striking feature. A large number of churches and universities were built in Europe in this style.

RENAISSANCE LITERATURE

• Renaissance writers gave importance to individual liberty and secular values.
• The basic characteristic of Renaissance literature was its breaking away from the scholasticism of the Middle Ages.

Most Renaissance writers chose to produce their works in regional languages. Prose literature gained prominence during this period. Dante, the renowned author of The Divine Comedy, was a prominent literary figure during the Renaissance period. The poem’s theme revolves around Dante’s imagined pilgrimage through Hell, Purgatory, and Paradise. However, it also profoundly refects human emotions, patriotism, fascination for natural phenomena, and the longing for a unified and independent Italy. Dante wrote The Divine Comedy in the regional language.

Another world-renowned writer, Petrarch, was a leading exponent of humanism. His sonnets addressing Laura refected a bold and unique style. However, Petrarch remained committed to writing in Latin. Another notable Renaissance writer was Boccaccio, the author of the celebrated work ‘The Decameron’.

Niccolo Machiavelli’s work. The Prince, presents political thoughts. He believed that a ruler’s paramount responsibility is to maintain the authority and security of the state. He also believed that individuals are generally selfish, driven by a desire for power and material prosperity. He advocated that a head of state should remain impartial and avoid showing favouritism or obligation to specific groups among the subjects. In The Prince, Machiavelli portrays an administrator who is different from the traditional medieval feudal administrators.

During the Italian Renaissance, several women recognised the significance of humanism. Among them, the most notable was the humanist and writer Cassandra Fedele. She earned a name through her writings and speeches, emphasising the importance of providing higher education to women. Fedele maintained a lively correspondence with wealthy Italian lords who championed humanism. Her speeches and writings were printed, published, and popularised by several prominent publishing houses.

In due course, the influence of the Renaissance extended beyond Italy, impacting the literature of other countries. Consequently, numerous remarkable works were produced in other parts of the world.
Some of them are given below:

Author	Work	Country
Erasmus	In Praise of Folly	Netherlands
Geoffrey Chaucer	Canterbury Tales	England
Thomas More	Utopia	England
Miguel de Cervantes	Don Quixote	Spain
Francois Rabelais	Gargantua and Pantagruel	France

Printing played a significant role in popularising literature during the Renaissance period. Johannes Gutenberg established the first printing press in Europe. The printing machine, which was set up in the 15th century, was made of metal and was of movable type. The influence of the printing press on the society of that period includes the dissemination of knowledge, Progress in literacy, Spread of Humanist Ideas, and Rise of the Reformation. With the invention of the printing press, people started reading literary works extensively.

RENAISSANCE AND HISTORIOGRAPHY

• This classification divides history into three distinct periods:
  • the Ancient Period, spanning up to the 5th century CE;
  • the Medieval Period, extending from the 5th to the 15th century;
  • the Modern Period, encompassing the era thereafter.
• This classification emerged during the Renaissance period. It was introduced by two Italian historians,
  Flavio Biondo and Leonardo Bruni.

The transition from medieval Christian tradition to a secular life and thought was also reflected in the realm of historiography. During the Middle Ages, the prevailing notion was that historical events were divinely ordained and supernatural powers governed the course of history. This perspective lost its relevance during the Renaissance period. Instead, human-centered explanations and interpretations gained recognition. Human life became the focus of historical narratives, superseding the chronicles of monks and biographies of priests.

• Another significant development in historiography during the Renaissance was the growing importance of archaeological evidence and relics. Thus, historians began to place greater emphasis on evidence such as inscriptions, coins, and ancient manuscripts in their narratives. Furthermore, efforts to collect and preserve ancient manuscripts intensified.
• With the emergence of humanism, critical thinking gained significance in history. Scientific enquiry and studies replaced stories and myths. The contributions of Machiavelli to Renaissance historiography are noteworthy.

Chronicles
Monarchs traditionally appointed court historians to record the events of their kingdoms. These historians documented the events during the reigns of their patrons. Modern historians have labelled these texts as “Chronicles” as they provide a continuous, chronological account of events.

RENAISSANCE AND SCIENCE

• The Renaissance laid the foundation for the evolution of modern science.
• Scientists put forward a groundbreaking view that material forces govern planetary motions.
• The revolutionary discoveries of Copernicus were further elucidated and expanded upon by Galileo Galilei and Johannes Kepler.
• Galileo Galilei made seminal discoveries, including satellites of Jupiter and rings of Saturn.
• The Renaissance also witnessed significant advancements in the field of medicine, particularly anatomy.
  “In the year sixteen hundred and nine the light of Science shone in his modest house in Padua as Galileo set out to prove that the Sun is fixed and the earth is on the move ”,

This is the introduction of the play on the life of Galileo by the famous German play wright Bertolt Brecht. Until the 16th century, the belief that the earth was the centre of the universe prevailed. These lines refer to the attempts made by Galileo, who challenged and negated the geocentric belief.

Remarkable transformations took place in the field of astronomy during this period. The geocentric model of Ptolemy, which positioned the Earth at the center of the universe, remained unchallenged until the 16th century. Later, Nicolaus Copernicus, a Polish astronomer and priest, challenged this prevailing doctrine. He presented a revolutionary argument that the centre of the universe is not the Earth but the Sun. Through his observations, Copernicus demonstrated that the Earth and the other planets revolve around the Sun. Kepler’s path-breaking findings revealed that the speed of planets varied based on their distance from the Sun, which laid the foundation towards the end of the 17th century for Isaac Newton’s formulation of the theory of gravitation. Galileo’s findings provided conclusive evidence in support of Copernicus’ principles.

The Swiss scientist Paracelsus conducted extensive research on the causes of diseases and tried to develop remedies. Meanwhile, Andreas Vesalius pioneered the study of human anatomy through the meticulous dissection of cadavers, thereby contributing substantially to the field of human anatomy.

THE REFORMATION

• The influence of the Renaissance extended to the realm of religion in Europe.
• The universities of Germany, particularly Wittenberg University, where Martin Luther taught, played an important role in laying the groundwork for the Reformation.
• The Reformation, which originated in Germany, soon spread to other European kingdoms.
• Following the Reformation, the Catholic Church initiated efforts to reform itself. This movement is known as the Counter-Reformation.

Satirical works penned by humanists like Erasmus, coupled with critiques from John Wycliffe, Jan Hus, and Savonarola, laid the groundwork for protests against certain practices and beliefs within the Catholic Church. One contentious issue was the sale of indulgences, where the Church would collect money from believers. Church authorities proclaimed that purchasing indulgences would redeem individuals of their sins. The money thus collected was proposed to fund the construction of hospitals and cathedrals. However, when Johann Tetzel, a Dominican monk, arrived in Germany to promote the sale of indulgences. Martin Luther, a priest, responded by pasting his famous ‘Ninety-Five Theses’ on the doors of the Wittenberg Cathedral in 1517. This pivotal event marked the beginning of the Protestant Reformation. Initially, Luther’s intention was merely to spark an ideological debate. So, he wrote his theses in Latin instead of German. However, his work was translated into German without his knowledge and, as a result, was widely disseminated. Subsequently, Luther severed his ties with the Church.

The interests of secular rulers who wished to limit the powers of the clergy and church courts further encouraged the Reformation. Many rulers had grown dissatisfied with the extensive powers of the clergy, particularly in matters of taxation and ecclesiastical appointments. Huldrych Zwingli and John Calvin in Switzerland assumed leadership in the Reformation movement. In England, King Henry VIII led the Reformation, and the Anglican Church emerged there with the monarch serving as its head. This development led to the establishment of the National Church.

COUNTER REFORMATION

• Following the Reformation, the Catholic Church initiated efforts to reform itself. This movement is known as the Counter-Reformation.
• Counter-Reformation is also known as Catholic Reformation.

As part of this initiative, the Church leadership convened the Council (Synod) of Trent in Northern Italy. The objectives of this council were to correct erroneous tendencies within the Church and to implement reforms. As a result, the sale of indulgences was banned. A list of books (The Index) that the believers should not read was published. The court of inquisition, which was there in Medieval times, was reinstituted.

The Society of Jesus, set up by Ignatius Loyola, a Spanish priest, also played a prominent part in Counter Reformation. Its members were bound to observe strict discipline and unquestioned obedience. They tried to establish the authority of the Catholic Church by setting up schools and engaging in active missionary work. Counter Reformation succeeded in eliminating a number of wrong tendencies in the Catholic Church. Counter-Reformation is also known as Catholic Reformation.
