Earth moves constantly. It spins on its axis. It orbits the sun. Parts of Earth even move from the inside out — constantly changing our planet’s surface.
For billions of years, Earth has been remodeling itself. Huge masses of rock rise from deep inside Earth, travel along its surface and then sink back down. The process is known as plate tectonics.
We rarely see those changes as they happen. Yet plate tectonics affects everyone. It influences climate. It can trigger earthquakes or volcanic eruptions. Plate tectonics even shapes continents. But scientists still don’t know all the details of how Earth alters its surface.
