Detailed explanation-1: -Thus, the increasing amount of cloud cover, ice and glaciers can help in decreasing the amount of absorption of these solar radiations.
Detailed explanation-2: -Due to the curvature of the Earth, a beam of light striking the Equator passes through less atmosphere than one at a higher latitude. As the amount of atmosphere through which the beam passes increases, the greater the chance for reflection and scattering of light to occur, thus reducing insolation at the surface.
Detailed explanation-3: -Reflection of Insolation – Approximately 34% of insolation received by the Earth is reflected back into space by clouds (25%), snow, ice caps, and water. E. Scattering of Insolation – Insolation can be scattered by molecules of gas, water, or dust in the Earth’s Atmosphere. This is why the sky is blue.
Detailed explanation-4: -Rotation of the earth on its axis. The angle of incidence of the sun’s rays. Duration of the day. Transparency of the atmosphere. 26-Jan-2017
