Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics at divergent boundaries.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and is forced into the mantle.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.
