WebApr 11, 2024 · Seamounts can also form in a variety of oceanic tectonic settings: along a mid-ocean ridge, in an oceanic intraplate position, or near a subduction zone (e.g., Koppers and Watts, 2010; Wessel, 2007), roughly representing the early, middle, and late periods of oceanic crust evolution, respectively. WebMid-ocean ridges are part of chain of mountains some 84,000 km long. The Mid-Atlantic Ridge is the longest mountain chain on Earth. These ridges are spreading centers or divergent plate boundaries where the upwelling of magma from the mantle creates new ocean floor. Deep-sea trenches are long, narrow basins which extend 8-11 km below …
