Front

What is plate tectonics?

Back

The theory that explains the movement of the Earth's plates and how they interact with each other.

Front

What are tectonic plates?

Back

Large sections of the Earth's crust that move and interact with one another.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is sedimentation?

Back
