Front

What are tectonic plates?

Back

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

Front

What is the lithosphere?

Back

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

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide or move towards each other.

Front

What is a transform boundary?

Back

A tectonic plate boundary where two plates slide past each other horizontally.
