Rift Valley, in terms of the theory of plate tectonics, occur in divergence zones were two of the various lithospheric plates that make up the Earth’s surface are separating. Numerous submarine rift valleys have been discovered along the crests of the large ridges that run throughout the Earth’s oceans. These ridges are centers of seafloor spreading: areas where the magma from the mantle is welling up, cooling to form the new oceanic crust, and is moving away from the crests in either direction.
