Overview
Third planet from the sun and the only known planet to harbor life. About 29.2% of Earth's surface is land with remaining 70.8% is covered with water. Earth's distance from the Sun, physical properties and geological history have allowed life to evolve and thrive.
Internal Structure
Earth's interior, like that of the other terrestrial planets, is divided into layers by their chemical or physical (rheological) properties. The outer layer is a chemically distinct silicate solid crust, which is underlain by a highly viscous solid mantle.
Surface Geology
Earth's surface is diverse, with mountains, valleys, plains, and bodies of water.
