Oceans form by the process known as

Back

Plates that horizontally slide past each other are called

Back

Transform

Front

Plates that move towards each other are called

Back

Convergent

Front

What occurs when an Ocean Plate and a Continental Plate collide?

Back

The ocean plate moves under the continental plate and sinks into the mantle.

Front

What occurs when two Continental Plates collide?
