Trends of 'incipit'. Used Rarely. incipit is in the lower 50% of commonly used words in the Collins dictionary.
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.
These plates drift on the asthenosphere at very slow rates. As plates move away from each other the lithosphere thins and tears. At these divergent plate boundaries new oceanic lithosphere is created in the gaps from upwelling magma from the mantle.
