What is the difference between the Oceanic Crust and the Continental Crust?

Back

The Oceanic Crust is thinner and denser than the Continental Crust, which is thicker and less dense.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.
