"WebThe Seafloor spreading theory was proposed by the geophysicist Harry H. Hess in 1960. It is a phenomenon that happens at mid-ocean ridges, where new oceanic crust is formed by volcanic activity and then slowly moves away from the ridge. The basis of the theory is the fact that the age of the rocks of the seafloor is not the same throughout history. " - How is sea floor spreading created
