In the 1960s, scientists developed a revolutionary theory called plate tectonics. Plate tectonics holds that the lithosphere, a layer of rigid material composed of the outer crust and the very top of the mantle, is divided into seven large plates and several more smaller plates. This sort of magma production is called subduction zone volcanism. 2  If the plates collide and neither plate can subduct under the other, the crust material will just crumple, pushing up mountains. 3  This process does not produce volcanoes.
