* Convergent boundaries: These are boundaries where two plates are moving towards each other. When two continental plates collide, they can form mountains. When an oceanic plate and a continental plate collide, the oceanic plate can be subducted under the continental plate, forming a trench.
* Divergent boundaries: These are boundaries where two plates are moving away from each other. As the plates move apart, new oceanic crust is formed in the gap between them.
* Transform boundaries: These are boundaries where two plates are sliding past each other. Transform boundaries can be strike-slip faults, where the plates are moving horizontally past each other, or dip-slip faults, where the plates are moving vertically past each other.
