WebHypothesis. Sea-floor spreading — In the early 1960s, Princeton geologist Harry Hess proposed the hypothesis of sea-floor spreading, in which basaltic magma from the mantle rises to create new ocean floor at mid-ocean ridges.On each side of the ridge, sea floor moves from the ridge towards the deep-sea trenches, where it is subducted and recycled … WebMar 21, 2024 · The concept of seafloor spreading forms an integral part of the modern plate tectonics theory and helps to explain continental drift.The movement of oceanic plates at …
