Seafloor spreading. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.eafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere.
Sea floor spreading is actually the creation of new oceanic  basaltic crust at divergent plate boundaries called mid-ocean  ridges. Material from the asthenosphere becomes m â¦ olten as  convection currents cause it to rise toward the thin upraised  boundary between plates there.preading of seafloor occurs at the mid-ocean rifts, where there is a continuous flow of material rising from the mantle. There is not a unanimously accepted theory as to the â¦ cause of the rifting that is taking place.
