Why Temperatures Reduce As You Go High Up In The Sky

I guess we have all heard the phrase, "the higher you go the cooler it becomes." Most people do wonder why this is so yet when you move up into sky you get closer to the sun and therefore should be hotter there.

The sun radiates its rays to the earth in the form of short wave radiations. These radiations have a higher speed and are absorbed by the earth's surface. After enough energy has been absorbed, the excess is reflected back into the atmosphere but this time in long wave radiations. These barely reach far into the atmosphere because they are weak and therefore their energy still remains near the surface.

Another reasons is because of the greenhouse gases on the earth's surface. These gases trap and release heat energy more efficiently than natural atmospheric gases like nitrogen. This leads to accumulation of heat on the earth's surface.
