Subduction Zone Processes Illustration Stock Image C040 3524 Subduction is possible because the cold and rigid oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle. once initiated, stable subduction is driven mostly by the negative buoyancy of the dense subducting lithosphere. Subduction zone, oceanic trench area marginal to a continent in which, according to the theory of plate tectonics, older and denser seafloor underthrusts the continental mass, dragging downward into the earth’s upper mantle the accumulated trench sediments.

In geological terms, subduction is the act of one tectonic plate moving under another tectonic plate at the point of their convergent boundary. as the subducting plate moves under its neighboring tectonic plate, gravity pushes it further down and into the mantle layer of the earth. When two tectonic plates meet at a subduction zone and one slides underneath the other, this lithosphere material curves down into the hot mantle. this subduction process frequently occurs. Subduction zones are responsible for powerful earthquakes, tsunamis and volcanic activity, making them some of the most geologically active and hazardous areas on earth.

Subduction, latin for "carried under," is a term used for a specific type of plate interaction. it happens when one lithospheric plate meets another—that is, in convergent zones —and the denser plate sinks down into the mantle. The meaning of subduction is the action or process in plate tectonics of the edge of one crustal plate descending below the edge of another. Subduction zones form where a plate with thinner (less buoyant) oceanic crust descends beneath a plate with thicker (more buoyant) continental crust. When this plate is forced to bend downwards, the process is called subduction. the process of subduction results in the formation of a zone called a subduction zone. the plate that bends usually curves down into the mantle. after curving, it forms a v shaped zone in the ocean that is very narrow.
