Front

What occurs at divergent boundaries?

Back

Tectonic plates move away from each other, leading to the formation of new oceanic crust.

Front

What happens at convergent boundaries?

Back

Tectonic plates move towards each other, which can result in subduction or mountain formation.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.
