The plates on Earth move quickly.

The mountains and volcanoes on Earth are pieced together.

The plates on Earth fit together like the pieces of a jigsaw puzzle.

The process by which plates move

Earth's crust is not recycled; it is only created.

As molten rock seeps out of weak spots in the crust, volcanoes are formed.

When plates slide past each other, creating friction, an earthquake forms.

As new crust is created, old crust is forced down deep inside Earth's mantle, where it becomes molten rock again.

The tectonic plates on Earth are continually moving at a slow rate.

The gravity on Earth causes the continents to move around.

Scientists think that the continents will move back into the shape of Pangaea again.
