It is called Seafloor spreading. Seafloor spreading is a process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge as shown in Figure 4. citimanager forgot password

"WebbThe rough ratio by area of oceanic to continental crust should remain roughly constant until plate tectonics shut down. And the interaction of plates will generally cause the uplifting of continental crust such that it tends to be exposed above the ocean, though sea level changes will also factor into that (much more than erosion, really).
