WebApr 25, 2024 · The seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess in 1960. Seafloor spreading is the process of magma welling up in the rift as the old crust pulls itself in opposite directions. Cold seawater cools the magma, creating a new crust. The upward movement and eventual cooling of this … WebNov 3, 2024 · What is the first step in seafloor spreading 2 See answers Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of …
WebApr 9, 2024 · One of the two major processes of plate tectonics is seafloor spreading, while the other being subduction. The renowned examples of mid-ocean ridges are the Mid- Atlantic Ridge and the East Pacific Rise. Seafloor spreading occurs at mid-ocean ridges and obtains basalt, the rock that forms the oceanic crust. Subduction zones are often … WebWhat are the steps in the process of sea-floor spreading? 1. A long crack in the oceanic crust forms at a mid ocean ridge. 2. Molten material rises and erupts along the ridge. 3. Older rock moves outward on both sides of the ridge. 4. Molten material cools and forms …
