What are transform plate boundaries?

Back

Transform plate boundaries are where two tectonic plates slide past each other, often causing earthquakes.

Front

What is the mantle?

Back

The mantle is the layer of Earth between the crust and the outer core, composed of semi-solid rock that flows slowly.
