SOLAR SYSTEM

Detailed explanation-1: -In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface.

Detailed explanation-2: -Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system. Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself.

Detailed explanation-3: -Of all of the solar radiation reaching Earth, 30% is reflected back to space and 70% is absorbed by the Earth (47%) and atmosphere (23%). The heat absorbed by the land and oceans is exchanged with the atmosphere through conduction, radiation, and latent heat (phase change).

Detailed explanation-4: -Approximately 2% of the solar energy striking the Earth’s surface is converted into kinetic energy in wind.
