As heated it rises in the crust (divergent boundary) commonly it rises in a divergent boundary. As it rises magma flows out and create new seafloor. Then the old seafloor was pushed in a convergent boundary to subduct in the mantle and burns. As known it repeats itself again and again. greenshot browser
