Two common types of plate boundaries are:

- Divergent boundary: plates move away from each other. Magma rises to fill the gap, creating new crust. Typical features/effects: mid-ocean ridges (e.g., Mid-Atlantic Ridge), rift valleys, volcanic activity and shallow earthquakes.

- Convergent boundary: plates move toward each other. One plate may sink beneath the other (subduction) or two continental plates may collide and crumple. Typical features/effects: volcanic arcs and deep earthquakes at oceanic–continental subduction (e.g., Andes), deep ocean trenches, and mountain ranges from continental collision (e.g., Himalayas).

(There is also a third major type, transform boundaries, where plates slide past one another horizontally, e.g., the San Andreas Fault.)
