At the MOR, molten rock is carried upward towards the surface via convection, where new oceanic lithosphere is generated (usually as an fine-grained igneous rock known as basalt) and the plates are further pushed away from the spreading center.
When one plate is composed of oceanic lithosphere and the other is composed of continental lithosphere, the denser oceanic plate is subducted, often forming an orogenic belt and associated mountain range. This type of convergent boundary is similar to the Andes or the Cascade Range in North America. subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either continental or oceanic crust.
