Terrestrial life would become impossible with Change in atmosphere permitting all solar radiations to reach lithosphere.
Earth's climate system is a complex system having five interacting components: the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere.
The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. 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.
