We are learning about the formation of the ozone layer and what it does to protect us from the sun's rays. We are up in the sky trying to watch it form, but there is not much to see, although there are hundreds of comets and meteors flying into the earth because there is no atmosphere there to stop them. A lot of these objects flying at the earth contain water and ice, and that is melting and creating the early stages of our oceans. Our atmosphere today was probably formed by photosynthesis, which released oxygen and helped to form our current atmosphere. When our atmosphere formed it began raining, which helped to form the rest of our oceans. Our atmosphere today is composed of oxygen, helium, hydrogen, and other gases. The formation of the Ozone layer is what allows modern life to exist today. Our Ozone layer is destroyed and reformed by a series of chemical reactions with the sun's UV Rays. It starts as O2(Oxygen) then is broken apart and joins with another to form O3(Ozone), then it either goes back toO2, or O, then goes through the process. This is extremely important to life on earth because O3 blocks out the Sun's harmful rays. Without this process we would not be able to live on land and the only life that would be able to survive on earth would have to be extremely deep under water.
