Two oceanic plates (OP) move away from each other, allowing magma to rise up from inside the Earth. The magma reaches the bottom of the ocean, turns in to lava and cools (forming new rock). This cycle continues constantly spreading the sea floor and adding new material along this chain of mountains. Sea Floor spreading occurs at these mid-ocean ridges.
