WitrynaWhen the continental crust slab is encountered by the oceanic crust, it becomes completely subducted due to the higher density. This process forces the oceanic crust to return toward the mantle by remelting into the magma. Same process causes the continental crust movements across the earth’s surface ( Fig. 8.27 ).
