This evidence led scientists to look again at Wegener's hypothesis of continental drift. Hope this helps 10. Seafloor Spreading evidence Answer: WebSeafloor 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. The idea that the seafloor itself moves (and carries the continents with it) expands from a central axis proposed by Harry Hess. how to add degrees minutes seconds
