Earths Atmosphere

The Earths atmosphere is different from the moons and other planets in many ways. First off a planet with no atmosphere is not suitable for living things and earths atmosphere is. There might not be enough nitrogen for a person and we need nitrogen to be able to live. The moon is not suitable for us because there might not be all of the gases for us to live and we would not be used to it so more then likely we would die . The other way earths atmosphere differs from other planets or the moon is the temperature is does not stay in if there is no atmosphere, and since the earth does have an atmosphere the temperature does stay in. That is how Earths atmosphere is different from a planet that has no atmosphere or then the moons atmosphere.
