The sinking of an oceanic plate edge as a result of convergence with a plate of lesser density Subduction often causes earthquakes and creates volcano chains
The process in which one lithospheric plate collides with and is forced down under another plate and drawn back into the Earth's mantle
a geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate
n the process of sliding under another object; including one crustal plate sliding beneath another at a subduction zone
Process of plate tectonics where one lithospheric plate is pushed below another into the asthenosphere
The process of the oceanic lithosphere colliding with and descending beneath the continental lithosphere
The process by which oceanic crust of one lithospheric plate moves down beneath oceanic or continental crust of another plate, resulting in the formation of a deep ocean trench, an inclined zone of earthquake activity (Benioff Zone) and volcanic activity due to the melting of the subducting plate
A place of the planetary crust where a tectonic plate slides downward These zones are where sections of the ocean's floor are pushed under continents This process builds mountains and sparks volcanism in these areas It's more so a cause and effect of up and down
The limit between converging plates, along which the oceanic lithosphere of a plate plunges below another plate It occurs at active continental margins and island arcs Over the plunging plate, volcanic ranges develop, the best known being the Pacific ring of fire
Oceanic trench area in which, according to the theory of plate tectonics, the seafloor underthrusts an adjacent plate, dragging the accumulated trench sediments downward into the Earth's upper mantle. See also deep-sea trench
The place where two lithosphere plates come together, one riding over the other Most volcanoes on land occur parallel to and inland from the boundary between the two plates
An elongated region along which a plate descends relative to another plate, for example, the descent of the Nazca plate beneath the South American plate along the Peru-Chile Trench
