Volcanoes: Islands-When the oceanic oceanic converge, one subducts and starts to melt and the melted crust rises and comes out of the inside of Earth. Land-When the oceanic continental converge the oceanic subducts and melts then the melted crust rises and comes out of the Earth.
Mountains: Continental Continental crust converge to form mountains. the mountains are formed when the crusts converge because the crusts have the same density so they can only go up and they do.
Mid Ocean Ridge: Seafloor spreading is when new ocean floor moving outward across ocean basins, and sinking back into the mantle beneath deep ocean trenches.
Rift Valley:When a spreading center forms on land, the process can split a continent apart when the forces of plate motion begins to stretch part of the lithosphere plumes of hot rock rise from the mantle.
Intraplate Volcanoes: Volcanoes that are in the center of a plate.
