Web10 apr. 2024 · Harry Hess proposed the theory of SeaFloor Spreading in 1961. He stated that new lava pushes out the plates from the mid-oceanic ridge. Paleomagnetic studies of the ocean floor reveal that there is an intense volcanic eruption and the huge amount of lava is coming out along the mid-Atlantic ridges. WebDescribe this hypothesis. What was this hypothesis missing? The Hypothesis stated that there was a supercontinent called Pangea, although, it eventually broke apart and each continent would then fall into its modern position It missed how they broke, which could then be explained by the theory of seafloor spreading 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. hat studio london
