Answers (2)


Atmosphere is the thick blanket of air that covers the whole of the Earth. Atmosphere acts as a blanket in the following ways:

(i) It prevents the harmful UV rays from reaching the Earth's surface. 

(ii) It helps in maintaining the surface temperature during day and night.

(iii) It protects Earth from celestial objects like asteroids.
