Plates do not cause volcanoes. Volcanoes generally form at the boundaries between plates. They form at convergent and divergent boundaries.

Collisions of plates
Mountains usually form on plate boundaries, where two tectonic plates collide and force the ground upward. There are very few volcanic mountains, such as the Hawaiian Islands, that form in the middle of the plates.
mountains are made when the crust folds, tilts ,and lifts as a result of this meeting of plates.

There are 3 main types of boundaries between plates: Convergent- when two plates are coming together (mostly form mountains) Divergent- when two plates are moving apart (mostly form rift valleys) Transform- when two plates slide past one another (also called strike-slip)
In plate tectonics, divergent boundaries occur when plates pull apart. On land, divergent boundaries form rifts or valleys. More commonly, divergent boundaries in the ocean occur and cause mid-oceanic ridges. Divergent boundaries can also form volcanoes when the plates separate enough to allow molten lava to seep out, harden, and eventually form islands.
