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.
