Large sections of the Earth's lithosphere that move and interact with one another.

Front

What is a fault line?

Back

A fracture in the Earth's crust where blocks of land have moved past each other.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another, leading to geological activity.
