The Prosses Of Creating A New Ocean Floor Is Called

Land masses move by ocean floor spreading which is the process in which the underwater volcanoes at rift zones make new ocean floor causing the old ocean floor to sub duct in a trench. Plates that are not subducting are driven by gravity sliding off the elevated mid ocean ridges a process called ridge push. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.
