Q : 2 How does the atmosphere act as a blanket?
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.
like blanket air is bad conductor of heat so the atmosphere controls the atmosphere rise in day time and temperature loss at night and hence the average temperature remains nearly similar .
