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 boundary between two plates can be a divergent boundary, a convergent boundary or a transform boundary. 2  The lithosphere is composed of the crust, and some of the upper mantle. 3  Mature oceanic plate is approximately 80-100 km thick, of which, the upper 5-7 km is oceanic crust. A single plate may be part oceanic and part continental. 2  In that case, the boundary between ocean crust and continental crust is not a plate boundary. 3  The mobile part of the mantle under the lithosphere is called the asthenosphere.
