The Earth has only one satellite, the Moon . The Moon is the second brightest object in the sky. The surface features on Earth are extremely varied with vast oceans, tall mountains, rolling plains, canyons, swamps, and deserts. The planet would be much colder without greenhouse gasses, such as carbon dioxide and water vapor, to trap outgoing thermal radiation. The motion of these plates is called tectonic drift.
Tectonic drift is responsible for seafloor spreading and continental drift.
