There are three main types of plate boundaries: 1. Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. The denser plate is subducted underneath the less dense plate.The plate being forced under is eventually melted and destroyed.i.here are three main types of plate boundaries: 1.
