How does seafloor spreading move continents
WebSimilar to Wegener’s theory that continents do in fact move, Hess’ seafloor spreading contradicted Wegener’s continental drift in that it involved the ocean sea floor moving as it expanded—instead of continents ploughing … WebSep 27, 2024 · Seafloor spreading creates new oceanic crust at a mid-ocean ridge. On one side, the oceanic crust is subducted below the continental crust. On the other side, the two plates collide in a transform boundary, which is a horizontal type of movement. The latter is the closest we really come to continents drifting.
