Q 4 - Why is clear sky night cooler than the cloudy sky night?

A - Radiation

B - Insolation

C - Conduction

D - Convection

Answer : A

Explanation

In a clear sky, heat radiated from the earth's surface, easily gets escaped into space, and resultantly, the temperature goes down; on the other hand, in cloudy night, heat remained trapped in the earths atmosphere.

Answer : A
