Scientists have discovered a new ultra-slow class of ocean ridge involved in seafloor spreading. Investigations in the far south Atlantic and Indian Oceans and the seafloor beneath the Arctic icecap have found that for large regions there, the seafloor splits apart by pulling up solid rock from deep within the Earth. These rocks, known as peridotites, come from the deep layer of the Earth known as the mantle.
Known ocean ridges, like the MidAtlantic Ridge and the East Pacific Rise, include regularly spaced volcanoes that continuously create a layer of crust on the seafloor. Mantle rocks are o...
