There are 3 types of boundaries; convergent, divergent and transform.

Convergent boundary is when two plates come together. When one part moves down and the other stays on top forming Mountains and Volcano. Subduction zone is when one plate goes under another creating a volcano and trench. Deep-sea trenches Mountain building is created when part moves down and the other stays on top.

Divergent boundary is when one parts move away from each other creating a new ocean floor or rift valley.

Transform boundary is when both plates moves in both ways, back and forth. This movement creates earthquakes or a tsunami if it is under the ocean.
