This is in contrast to a constructive plate boundary (also known as a mid-ocean ridge or spreading center). As a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near destructive boundaries, where subduction zones or an area of continental collision (depending on the nature of the plates involved) occurs . The subducting plate in a subduction zone is normally oceanic crust, and 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 . In other regions, a divergent boundary or transform faults may be present . </P> <Table> <Tr> <Td> Oceanic - continental </Td> <Td> Continental - continental </Td> <Td> Oceanic - oceanic </Td> </Tr> </Table>
