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 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 …

Mar 11, 2025 · 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 occurs at convergent boundaries, which are regions where two tectonic plates collide. The process of subduction leads to significant geological activity, often resulting in powerful earthquakes …

Sep 7, 2020 · Where they collide and one plate is thrust beneath another (a subduction zone), the most powerful earthquakes, tsunamis, volcanic eruptions, and landslides occur.

Dec 30, 2024 · 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 …

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.

Jan 17, 2020 · 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 …

The definition of subduction is the process that occurs when two tectonic plates meet at convergent boundaries, and one of the plates moves under the other one due to gravity and differences in...

Subduction zones form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust.
