Web22 de set. de 2024 · The Mid-Atlantic Ridge is a giant rift valley that runs along the Atlantic Ocean floor from north to south. It was formed by tectonic forces and diverging plates. At the spreading center on a mid-ocean ridge, the depth of the seafloor is approximately 2,600 meters (8,500 ft). On the ridge flanks, the depth of the seafloor (or the height of a location on a mid-ocean ridge above a base-level) is correlated with its age (age of the lithosphere where depth is measured). The depth-age relation can be modeled by the cooling of a lithosphere plate or mantle half-space. A good approximation is that the depth of the seafloor at a location on a spre…
