There are three types of tectonic plate boundaries. When two plates slide past each other, they form a --------- boundary. A --------- boundary occurs when two plates pull away from each other. When two plates collide with each other, they form a -------- boundary.

When two plates slide past each other, they form a transform boundary. A divergent boundary occurs when two plates pull away from each other. When two plates collide with each other, they form a convergent boundary.
