Answer:
Maps representing natural features such as physiography, climate, etc., are called physical maps. Maps representing man-made features such as agriculture, industry, and political boundaries are called cultural maps.
Question 6.

Answer:
Topographical maps are prepared based on comprehensive land surveys. These maps show both natural and man made features in detail. Detailed information on relief, topography, rivers, forests, agricultural lands, towns, means of transport and communication, settlements, etc. are included in topographical maps.
Question 7.
What are the requirements for map reading.
Answer:
- Knowledge of scale
- Knowledge of direction
- Knowledge of signs and symbols
Question 8.
Discuss the three methods to show the scale. What are the purpose of these 3 methods of scale?
Answer:
1. Statement Scale
Which among the scales given in the map is easy for us to understand? Isn’t it the one shown as 1 cm to 5 km? This method of representing the scale is the statement scale. From this we can easily understand that one centimeter on the map represents 5 km on earth. The merit of this method is that even a layman can easily understand this.
2. Representative fraction
Representative fractions is used to avoid this problem. Representative fraction is the ratio between the map distance and corresponding ground distance expressed in fractional from. For example, the statement of scale 1 cm to 5 kilometers, can be represented as 1:500000 in representative fraction. This proportionate distance can be read in accordance with the units followed in each country. While the Indians read this as 1 centimeters to 500000 centimeters, the Europeans can read this as 1 inch to 500000 inches. Now you might have understood the use of rep- resentative fraction.
3. Linear Scale
Look at the scale shown in the linear method. You can see that the linear scale has changed in proportionate with the change in the map. When a map is subjected to enlargement or reduction, the linear scale will also change accordingly. This is the merit of this method.
Question 9.
How to measure distances on maps? Explain with the help of suitable example.
Answer:
To measure straight distance, a ruler can be used. If it is a curved distance such as a river or a curved path, First measure the distance using a thread and then measure the length of the thread. Now you have the map distance. What should be done to find the actual distances? For this, the map distance should be multiplied with the proportionate ground distance shown in the map scale. For example,
Scale of the map is 1 cm to 5 km
Suppose the distance from A to B in the is 4 cm.
Then the actual distance from
A to B = 4 × 5 km = 20 km
Question 10.
What are the functions of the survey India?
Answer:
The survey of India is the agency responsible for making, scrutinising, and publishing maps in our country.
Question 11.

- For meteorological studies.
- For military purposes.
- For understanding the political boundaries.
- For the study of history
- Maps depicting specific themes are known as thematic maps
Based on function, maps can be classified into two. They are:- - Physical maps
- Cultural maps
- Maps representing natural features such as physiography, climate, etc. are called physical maps.
- Maps representing man-made features such as agriculture, inddstry, and political boundaries are called cultural maps.

| Physical map | Cultural map |
| Natural vegetation map | Political map |
| Soil map | Agricultural map |
| Astronomical map | Industrial map |
| Physiography map | Military map |

- Maps are classified based on the scales they correspond to:
- If larger areas such as the world, continents, countries, and states are to be depicted in a small sheet of paper, only a little information can be incorporated into it. Maps showing only the important information of larger areas are called small scale maps.
- If the area to be depicted is a comparatively small region like a ward or village, more information can be incorporated in it.
- Maps representing detailed information of a small area are called large scale maps.
Maps are prepared on specific scales and there are three different methods to show the scale – statement scale, representative fraction, and linear scale. - The method of representing the scale in a statement form is called a statement scale.
- Representative fraction is the ratio between the map distance and corresponding ground distance expressed in fractional form.
