- Divergent Boundaries –
- Here the plates pull away from each other.
- Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.
- Divergent boundaries also form volcanic islands.

- The location where the sinking of a plate occurs is called a subduction zone.
- The subducting plate in a subduction zone is normally an oceanic crust.
