Destructive plate margin; oceanic crust is forced below the continental crust because oceanic crust is denser than continental crust. Friction between the moving plates causes earthquakes. The heat increase due to friction and being pushed into the asthenosphere causes the oceanic crust to evaporate, and reduced density forces the newly formed magma to rise. The magma rises up through weak areas in the continental crust, eventually erupting as one or more volcanoes.
