the process by which two tectonic plates collide, and one is forced to pass under the other, usually associated with mountains, volcanoes and earthquakes.
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.
Subsidence of the leading edge of a lithospheric plate into the mantle.
zone region where one tectonic plate pushes downward beneath the edge of another into Earth's upper mantle
The sinking of oceanic crust underneath overriding continental crust at a subduction zone.
this is the process in which the edge of one lithospheric plate descends below the edge of another.
plate tectonics: as a heavy oceanic plate and a lighter continental plate collide with one another, the heavier oceanic plate slides downward and under the continental plate.
the process by which oceanic lithosphere is conveyed down into the mantle at destructive plate margins. The area in whch this takes place is called a subduction zone, the surface expression
a geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate
the process of one tectonic plate diving beneath another.
The process in which one plate is pushed downward beneath another plate into the underlying mantle when plates move towards eachother.
A plate tectonics term for the process through which an oceanic lithosphere collides with and descends beneath the earth's continental lithosphere.
Process in which a plate of dense oceanic lithosphere sinks back into Earth's interior along a dipping surface that separates it from the overriding lithosphere and asthenosphere.
the process whereby the edge of one crustal plate descends below the edge of another.
Process of one crustal plate sliding down and below another crustal plate as the two converge. The subduction zone is the area between the two plates, somewhat like a giant reverse fault. more details...
The process in which one tectonic plate is submerged below another along a line where two plates collide. A subduction zone is usually characterized by a deep trench and an adjoining mountain range.
The process in which one lithospheric plate collides with and is forced down under another plate and drawn back into the Earth's mantle.
Plunging of oceanic plates along trenches either within the oceans or along their boundary with the continents.
process that takes place in deep-sea trenches, where earth's lithosphere descends into the asthenosphere below; the forcing of denser crust material underneath lighter crust material, causing the crust to melt and mix with new rock from the mantle.
The process by which one oceanic plate bends and sinks down into the asthenosphere beneath another plate.
The process by which one crustal block descends beneath another, such as descent of the Pacific plate beneath the Andean plate along the Andean Trench.
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 subduction is a phenomenon in which one part of the Earth's crust (a plate) is pushed underneath another plate as two plates collide. The descending crust melts as it is pushed deep into the Earth's mantle. Subduction destroys crust and recycles it back into the mantle.
Latin subducere "to drive under" Process of shoving-under, in the course of that one rock-plate ( lithosphere-plate) slide under the other, along the so-called subduction zones.
n. A geologic process in which one edge of one crustal plate is forced below the edge of another; subduct subduction zone- n. A long narrow area in which subduction is taking place, e.g. the Peru-Chile trench, where the Pacific Plate is being subducted under the South American Plate.
The process of the oceanic lithosphere colliding with and descending beneath the continental lithosphere.
sinking of the oceanic crust in the upper mantle along an inclined plane: Benioff plane or subduction zone.
the geologic process whereby one continental plate slides under another and is gradually consumed in the Earth's interior.
the process of one part of the earth's crust moving beneath another along plate boundaries, resulting in chains of volcanoes and parallel formations of uplifted sedimentary rock
The process in which one huge plate of the earth's crust descends beneath another plate.
The process of one lithospheric plate descending beneath another.
The process by which one tectonic plate moves beneath another.
In geology, a subduction zone is an area on Earth where two tectonic plates meet and move towards one another, with one sliding underneath the other and moving down into the mantle, at rates typically measured in centimeters per year. An oceanic plate ordinarily slides underneath a continental plate; this often creates a zone with many volcanoes and earthquakes. In a sense, subduction zones are the opposite of divergent boundaries, areas where material rises up from the mantle and plates are moving apart.
