EXPLANATION:
There are 3 primary types of Tectonic Plate boundaries: Divergent boundaries; Covergent boundaries; and Transform boundaries.

Divergent Boundaries:At divergent boundaries new crust is created as two or more plates pull away from each other. Oceans are born and grow wider where plates diverge or pull apart.
Convergent Boundaries: Here crust is destroyed and recycled back into the interior of the Earth as one plate dives under another. These are known as Subduction Zones - mountains and volcanoes are often found where plates converge. There are 3 types of convergent boundaries:
Oceanic-Continental Convergence; Oceanic-Oceanic Convergence; and Continental-Continental Convergence. (Benioff zone is a deep active seismic area in a subduction zone)
Transform-Fault Boundaries: Transform-Fault Boundaries are where two plates are sliding horizontally past one another. These are also known as transform boundaries or more commonly as faults.
Most transform faults are found on the ocean floor.
