convergent boundary definition
Convergent boundary. In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is an actively deforming region where two tectonic plates or fragments of lithosphere move toward one another and collide.n a subduction zone, the subducting plate, which is normally a plate with oceanic crust, moves beneath the other plate, which can be made of either oceanic or continental crust. During collisions between two continental plates, large mountain ranges, such as the Himalayas are formed.
