What is a divergent plate boundary?

Back

A tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What is a transform plate boundary?

Back

A tectonic plate boundary where two plates slide past one another horizontally, causing earthquakes.

Front

What is a stationary front?

Back
