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 …

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.

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.

Mar 6, 2018 · 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 …

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 …

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 …

Sep 6, 2022 · 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 form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust.

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 …
