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 6, 2022 · A subduction zone is a collision between two of Earth's tectonic plates, where one plate sinks into the mantle underneath the other plate.

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.

Subduction zones are defined by an inclined zone of earthquakes, the Wadati–Benioff zone, that dips away from the trench and extends down below the volcanic arc to the 660-kilometer discontinuity.

Dec 30, 2024 · The oceanic plates are comparatively heavier, so when these collide with the continental plates, they subduct downwards, forming a zone referred to as a subduction zone.

Subduction Zone: Definition, Features, Types A subduction zone is a geological feature where one tectonic plate moves under another and is forced back into the Earth's mantle.

Subduction zones are regions of the Earth's crust where one tectonic plate moves under another and sinks into the mantle. These zones are critical areas of geological activity, leading to the formation of …

Mar 11, 2025 · Subduction zones occur at convergent plate boundaries where two tectonic plates meet and one dives beneath the other. Volcano activity at subduction zone. A dense oceanic plate will be …

May 21, 2024 · What is a Subduction Zone? A subduction zone is a convergent boundary where two tectonic plates collide. Plates are large, dense masses in the crust of the Earth, the lithosphere, that …

SUBDUCTION ZONE definition: 1. an area where two continental plates (= large layers of rock that form the earth's surface) meet…. Learn more.
