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.
This molten rock or magma erupts on the seafloor to make a kind of volcanic rock called basalt,and it is this basalt that makes up the new seafloor (oceanic lithosphere).
