WebThis frozen lava becomes the new seafloor. Since new seafloor stays hot for a long time, it is more buoyant (floats higher) than the older seafloor, forming a high ridge that looks like an underwater mountain chain. We call this ridge where new seafloor is created a ‘mid-ocean ridge’. The same process happens in the middle of the Atlantic ... WebSeafloor spreading is the movement of old rock that is being pushed by the new young oceanic crust. This would be a divergent since the plates are separating from each other. Active seafloor spreading is occurring at mid-ocean ridges. See also Best answer: What is the shortest river in the United States? What is the youngest tectonic plate?
