Earth's Atmosphere

There are many ways the earths atmosphere helps the planets survival differing from planets with no atmosphere. Earths atmosphere acts like a shield when a meteor is aimed toward earths surface. The atmosphere helps it because when the meteor comes in contact with the earths atmosphere the friction against that meteor causes the meteor to overheat and burst into flames, causing the meteor to disintegrate. Unlike other planets or moons that don't have an atmosphere, any meteor aimed at that planet or moon will come in contact with the surface. From the cause of the impact the meteor becomes a meteoroid. In conclusion, those are the differences and benefits that earth has that other planets don't.
