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.
1 The lithosphere is composed of the crust, and some of the upper mantle. 2  Mature oceanic plate is approximately 80-100 km thick, of which, the upper 5-7 km is oceanic crust. 3  Continental plate is somewhat thicker, perhaps 150-200 km thick, and includes continental crust which varies from 5 to 70 km in thickness.
