Monday inquiry - Atmosphere.

The Atmosphere is an important part of the earth because it has most of our oxygen and alot of nitrogen. The closest layer to the earth is the Trososphere and the furthst layer about 2000Km away is the exosphere. The exophere is just basicly space because it's the furthest layer and the more further tha layer the more less dense it is. In the stratosphere we have the ozone layer that protect us from the powerful radiotion from the solar rays.
