                                  currents in the mantle cause the

                                  to form fold mountains.

As currents in the mantle cause the the plates move apart, tensional (Plate name) and (Plate name) to stresses cause fractures in the move towards each other and lithosphere. New basaltic converge. The denser oceanic magma wells up at the spreading plate is subducted under the centre where it cools and less dense continental plate. solidifies to form new sea floor. The sinking crust is melted in the magma due to immense pressure and heat. Less dense silica-rich magma then rises thru fractures in the crust to pour onto the ocean floor, forming undersea volcanoes. When they are built up and appear above the sea, they form volcanic islands.

Oceanic – Continental* Forms subduction volcanoes, oceanic trench, fold mountains Formation: Cooling and sinking convection currents in the mantle cause the (oceanic plate name) to converge and collide with the (continental plate name). The denser (oceanic plate name) subducts under the lighter (continental plate name), forming a narrow, linear depress- ion parallel to the boundary - called an oceanic trench. The subducted part of the (oceanic plate name) melts due to immense friction and heat in the mantle. The less dense silica-rich magma then rises thru fractures on the surface where it cools and solidifies to form subduction volcanoes. Due to compression of the rock strata of the (contin- ental plate name), the rock strata are bent, uplifted and contorted to form fold mountains. Formation of subduction volcanoes, fold mountains and oceanic trench
