It has an atmosphere composed primarily of nitrogen and oxygen and is the only planet on which water in liquid form exists, covering more than 70 percent of its surface. It is also the only planet on which life is known to have evolved, occupying the relatively thin region of water, land, and air known as the biosphere. Earth has a single, relatively large natural satellite, the Moon. See more at atmosphere core crust mantle. See Table at solar system.
