- Divergent plate boundary, which causes volcanic activity and shallow earthquakes.
- Convergent plate boundary, which has one plate that “dives (‘subducts’) beneath the other, resulting in a variety of earthquakes and a line of volcanos on the overriding plate”
- Transform plate boundary, where plates slide laterally past one another, producing shallow earthquakes but little to no volcanic activity.
- Hotspot, “where a plate rides over a rising plume of hot mantle, creating a line of volcanoes on top of the plate.”
