In a subduction zone which plate sinks
WebThere, usually the older, colder, and therefore denser plate sinks below another plate. Continental plates mostly consists of lighter material and can at most be partially subducted. The geodynamic process of one plate sliding beneath another occurs along deep-sea trenches and is called subduction. WebSubduction zones are plate boundaries where one plate slides underneath the other and then subducts (sinks) down into the mantle. Normally this happens between a continental plate and an oceanic plate, but subduction can happen between two oceanic plates as well.

Web1 day ago · Experts fear the Cascadia Subduction Zone could unleash an earthquake with a magnitude of –9 in the Pacific Northwest, activated by the hole, due to its chemically distinct leakage known as ... Webplate sinks (is subducted) under another. The location where sinking of a plate occurs is called a subduction zone. The type of convergence -- called by some a very slow "collision" -- that takes place between plates depends on the kind of lithosphere involved. Convergence can occur between an oceanic and a largely continental plate,
WebMay 4, 2015 · Now geologists at MIT have offered up an answer: India was pulled northward by the combination of two subduction zones — regions in the Earth’s mantle where the edge of one tectonic plate sinks under another plate. As one plate sinks, it pulls along any connected landmasses.

Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the … See more According to the theory of plate tectonics, the Earth's lithosphere, its rigid outer shell, is broken into sixteen larger tectonic plates and several smaller plates. These plates are in slow motion, due mostly to the pull force of subducting … See more Initiation of subduction Although stable subduction is fairly well understood, the process by which subduction is initiated remains a matter of discussion and … See more Modern-style subduction is characterized by low geothermal gradients and the associated formation of high-pressure low-temperature rocks such as eclogite and blueschist. Likewise, rock assemblages called ophiolites, associated with modern-style subduction, … See more Subduction zones are important for several reasons: • Subduction zone physics: Sinking of the oceanic lithosphere (sediments, crust, mantle), by the contrast of density between the cold and old lithosphere and the hot asthenospheric … See more Arc-trench complex The surface expression of subduction zones are arc-trench complexes.
