WebbThe sea-floor spreading hypothesis maintains that these plates are in constant motion and that seismic boundaries between them delineate zones where oceanic crust is created … WebbSeafloor spreading is only a part of the process moving continents. New oceanic crust material is sourced from mid-ocean ridges (MORs), but mechanisms such as ”mantle drag” are what is proposed to actually make the plates move. As the plates move apart, more tension is placed on the MOR allowing them to split more and release more crustal …
