Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What are tectonic plates?

Large pieces of the Earth's lithosphere that move and interact with each other.

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move away from each other, often creating new crust.

Front
