Question 4.
A. Appu and Ammu were observing the night sky from their terrace. Appu was confused about how to differentiate the stars and planets that they saw.
(a) Help Appu to clear his confusion.
Answer:
Stars are-self-luminous celestial bodies. But planets and satellites are not self-luminous. The light that falls on these bodies gets reflected and it makes them glow. We perceive them as luminous because of the reflection of light. While observing the sky, we see the stars twinkling whereas the planets shine without twinkling.

(b) What preparations are to be made for sky-watching?
Answer:

1. Choose a proper space where the sky is clearly visible.
2. Days closer to the new moon day are to be chosen.

Answer:

1. No air
2. Weight is not felt
3. No water

(c) What are artificial satellites? Explain with an example.
Answer:
Some machines equipped with cameras and many other devices have been built by humans and sent into space. They are constantly orbiting the Earth. These man-made machines are artificial satellites.
Eg: INSAT – India’s artificial satellite related to communication.

Question 5.
A) What is seed dispersal? Explain two ways animals contribute to seed dispersal with examples
Answer:
The movement or transport of seeds away from their parent plant to ensure the germination and survival
of some of the seeds plants is called seed dispersal.

Seed dispersal by animals:

1. Birds eat fruits and excrete seeds far from the parent plant (e.g., berries).
2. Animals carry seeds stuck to their fur (e.g., burdock seeds).

B) Coconut seeds float on water to reach faraway places. Explain how this adaptation helps in seed dispersal.
Answer:
Adaptation of coconut for seed dispersal:

• Buoyant due to its fibrous husk.
• Can float in water and travel to distant places.

C) Write about one plant whose seeds burst open to scatter and the importance of this process.
Answer:
Bursting seeds example:

1. Example: Balsam.
2. Importance: Ensures seeds scatter over a wide area for better growth opportunities.

Answer:
Chandrayaan missions:
