The seafloor spreading

WebMay 20, 2024 · Seafloor spreading is most dynamic along giant underwater mountain ranges known as mid-ocean ridges. As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other. The North American and Eurasian tectonic plates, for example, are separated by the Mid-Atlantic Ridge.

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. WebSeafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor.
