[14] Water is transported into the deep mantle via hydrous minerals in subducting slabs.

WebbA new way to explain continental drift was discovered in 1960s by American Geophysicist, Harry H. Hess. 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. Webb2 dec. 2010 · The process by which oceanic crust sinks into the mantle when it collides with continental crust? The oceanic crust is subducted underneath the continental crust. This process is known as subduction.

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).
