A convergent plate boundary is a type of plate boundary which two plates notably a continental and oceanic plate move toward each other and form subduction zones. The oceanic plate will subduct, while the continental plate will override due to difference in densities. The two other plate boundaries namely divergent and transform plate boundaries differ due to the events happening between the plates. In a divergent boundary two plates move away from each other forming ridges and rifts. While in a transform boundary two plates move horizontally past each other forming faults such as the San Andreas fault in California. In transform boundaries, plates one of the plates can either move in a sinistral or dextral direction.
