Consider the statements regarding insolation which is nothing but the radiant energy

received from the Sun in the form of heat and light.

1) Insolation received on the surface of the Earth decreases from Equator to the Poles.

2) During Summer Solstice, maximum insolation received at the ground surface is

between the 30 to 40 degree South latitudes.

3) Insolation received is comparatively higher in the outer limit of the atmosphere than

that is on the surface of the Earth.

Explanation:

Solar rays will have to travel longer distance to reach the polar region than the Equatorial
regions thus large amount of energy is lost due to scattering, diffraction, reflection etc. thus
higher insolation is experienced in the equatorial region.
Similarly the insolation is higher in the outer limits of the atmosphere.
In the second statement, the latitudes should have been North rather than South.
