As the plates split apart, they do so at differing speeds, creating space—anywhere from a few to several hundred miles—between spreading margins. As the plates in this space continue to diverge, … NettetThe process of seafloor spreading happens at mid-ocean ridges, where new oceanic crust is generated by volcanic activity and then progressively travels away from the ridge. Spreading of the seabed Harry Hess suggested the theory that the seafloor moves (and carries the continents with it) as it expands from a central axis. do you like community service
