Earth

space · our home · oceans

A water world. Oceans cover almost 71% of Earth's surface, and it's the only planet in the Solar System with liquid water on its surface.

Moving puzzle pieces. Earth's crust is made of slowly moving tectonic plates. When they bump and grind, they create mountains, volcanoes, and earthquakes.

Built-in shield. Earth's liquid outer core creates a magnetic field that deflects most of the harmful solar wind and cosmic radiation from space.

Giant ice sheets. The huge ice sheets at the poles hold more water than all of Earth's groundwater, lakes, rivers, and air moisture combined!

Third from the Sun. Earth is the third planet from the Sun, sitting in just the right spot for life to thrive.
