Question
CBSEENGE11010785

Distinguish between Insolation and Terrestrial Radiation.

Solution
Insolation: The incoming solar radiation is termed as insolation. It is mostly in the form of short waves. The earth's surface receives only 1/2000 millionth part of the total energy radiated from the surface of the sun. It raises the temperature of the land and water directly and that of the air indirectly.

Terrestrial radiation: Radiation from earth is called terrestrial radiation. The terrestrial radiation is in the form of long waves which are observed by the components of the atmosphere.
