Front

What are the five physical layers of Earth?

Back

The five physical layers of Earth are the crust, mantle, outer core, inner core, and the lithosphere.

Front

How do seismic waves help us understand Earth's layers?

Back

Seismic waves change speed and direction when they pass through different materials, allowing scientists to infer the structure and composition of Earth's layers.
