Internal Structure of the Earth

You might think of the Earth as just solid ground, but it's much more complex! Scientists have figured out a lot about what's inside by studying seismic waves – the vibrations caused by earthquakes. When an earthquake happens, these waves travel through the Earth, and how fast they travel or if they're reflected or refracted (bent) tells us a lot about the material they're passing through. Different materials have different densities and states (solid, liquid, or "plastic," meaning it flows very slowly).
