Subduction - Wikipedia
网页Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth's mantle at the convergent boundaries between tectonic plates. Where one tectonic plate converges with a second plate, the heavier plate dives beneath the other and sinks into the mantle.
Subduction: The Sinking of Tectonic Plates - ThoughtCo
网页2020年1月17日 · 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 —and the denser plate sinks down into the mantle.
Introduction to Subduction Zones: Amazing Events in Subduction Zones …
网页2020年9月7日 · Overview. The Earth’s many tectonic plates can be thousands of miles across and underlie both continents and oceans. These plates collide, slide past, and move apart from each other. Where they collide and one plate is thrust beneath another (a subduction zone), the most powerful earthquakes, tsunamis, volcanic eruptions, and …
What Is The Process Of Subduction? - WorldAtlas
网页2018年3月6日 · 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 neighboring tectonic plate, gravity pushes it further down and into the mantle layer of the earth.
Subduction zone | Plate Tectonics, Oceanic Crust & Volcanism
网页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 Earth’s upper mantle the accumulated trench sediments.
What is a subduction zone? - Live Science
网页2022年9月6日 · One of the biggest crash scenes on Earth, a subduction zone is a spot where two of the planet's tectonic plates collide and one dives, or subducts, beneath the other, according to the National...
Convergent Plate Boundaries—Subduction Zones
网页Subduction zones form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust.
Subducting carbon - Nature
网页2019年10月16日 · A hidden carbon cycle exists inside Earth. Every year, megatons of carbon disappear into subduction zones, affecting atmospheric carbon dioxide and oxygen over Earth’s history. Here we discuss ...
Subduction Animation - Earthguide Online Classroom
网页Subduction is a geological process in which the edge of a lithospheric plate slides underneath the edge of an adjacent plate. Subduction is one of the two major processes of plate tectonics, the other being seafloor spreading.
Subduction - Earthdata
网页2010年1月25日 · The process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate, sinking into the Earth's mantle, as the plates converge. A subduction zone is an area on Earth where two tectonic plates move towards one another and subduction occurs.
