When the suns rays strike the ground, a fraction of it is reflected towards space as heat (infrared
radiation). Greenhouse gases allow these rays to penetrate the atmosphere towards the earths
surface freely but blocks the infrared radiation from leaving
The Earths energy input is mainly from the suns radiation. This energy is reflected back to
space by the Earths surface. The reflected infrared radiation is blocked by the layer of
greenhouse gases in space and a fraction of it is scattered and absorbed b
