Front

What is the lithosphere?

Back

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

Front

Back

The semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What is a tectonic plate?

Back

A large slab of solid rock that makes up the Earth's lithosphere.

Front
