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 that is on the surface of the Earth.Choose the correct statement/s from the following codes.

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 that is on the surface of the Earth.
Choose the correct statement/s from the following codes.

1, 2 only.

2, 3 only.

1, 3 only.

All the above.

Explanation:
Solar rays will have to travel longer distance to reach the polar region than the Equatorialregions thus large amount of energy is lost due to scattering, diffraction, reflection etc. thushigher 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.
