Question

Distinguish between insolation and terrestrial radiation in geography

Answer 1

Hotter the object shorter is the length of the wave. (iv) Insolation reaches the earth's surface in short waves and heat is radiated from the earth in long waves. ... Hence energy leaving the earth's surface i.e. terrestrial radiationheats up the atmosphere more than the incoming solar radiation i.e.insolation.

Answer 2

Answer:Insolation and Terrestrial Radiation

Explanation:

Insolation - "The amount of solar radiation received on the earth's surface is called insolation." The sun's energy travels to the earth as electromagenetic radiation. The incoming solar radiation is received in the form of short waves. These waves reach the earth's surface without heating the atmosphere.

Terrestrial Radiation - Solar radiation in the form of short waves and it reaches the earth's surface without heating the atmosphere. Most of this heat energy is reflected back by the earth's surface in the form of a long - wave radiations known as the Terrestrial Radiation. The atmosphere is thus heated indirectly through the earth. Due to the fact that the source of heat for the air is the ground, it is the lower layers of the air which are heated more. Thus, the temperature of the atmosphere is higher near the ground and it falls say you go upward into the atmosphere.
