Our atmosphere is the thing that protects us humans and creatures from the suns ultra violet light rays. It also sustains life on this planet. It is the security that is over us. The atmosphere also gives us weather.
1) Protects us from harmful UV rays emitted from the sun. 2) Protects us from outer space debris. 3) Contains our oxygen. 4) Maintains equal temperature. (without atmosphere earth would be below freezing)
