what atmosphere layers have the most impact on the earth
Above the troposphere is the stratosphere, which includes the ozone layer. The stratosphere extends from about 10 to 30 miles above the surface of Earth. Ozone molecules, which are concentrated in this layer, absorb ultraviolet radiation from the Sun and protect us from its harmful effects. Thirty to 50 miles above the surface is the mesosphere, the coldest part of the atmosphere.
