WebHow are ocean trenches formed? A trench forms when one tectonic plate dives under another. For a long time the origin of ocean trenches was a complete mystery, and scholars were surprised to find them so close to shore, rather than in the very center of the oceans. WebThe oceanic plate is forced down into the mantle in a process known as "subduction." As the oceanic plate descends, it is forced into higher temperature environments. At a depth of about 100 miles (160 km), materials in the subducting plate begin to approach their melting temperatures and a process of partial melting begins. ADVERTISEMENT
Web31 mrt. 2024 · Oceanic Trenches are formed by a process called subduction, where two or more tectonic plates converge. The old denser plate slides beneath a younger, less-dense plate much deep into the mantle, resulting in the seafloor and lithospheric crust bending to form a deep V-shaped depression.
