The Earth's crust is primarily composed of solid rock, including minerals and elements.

Front

What is the role of the mantle in Earth's geology?

The mantle is a thick layer of semi-solid rock that flows slowly, driving plate tectonics.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another, often leading to volcanic activity.

Front

What is the significance of the outer core?

Back

The outer core is responsible for Earth's magnetic field due to its liquid iron and nickel composition.
