Being liquid, the newly created magmas rise faster than the upwelling mantle and escape toward the surface, forming the volcanic and intrusive igneous rocks of the oceanic crust. Conversion of solid (rock) to liquid (magma) absorbs heat, so the rising mantle and the resulting magma actually cool-down slightly as melting progresses. daddy presents from daughters
