Subduction - Wikipedia 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 | Plate Tectonics, Oceanic Crust Volcanism - Britannica 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
What Is a Subduction Zone? - Live Science 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
What Is The Process Of Subduction? - WorldAtlas 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
Subduction Zone Science: Definition, Example, And A Simple Explanation 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
Subduction Zone: Definition, Features, Types - Geology In A subduction zone is a region of the Earth's crust where two tectonic plates meet, and one plate is forced beneath the other into the mantle This process, called subduction, occurs at convergent boundaries and is a primary mechanism driving plate tectonics, leading to volcanic activity, earthquakes, and mountain formation
