  • Subduction - Wikipedia
    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
  • Introduction to Subduction Zones: Amazing Events in Subduction Zones
    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 landslides occur
  • Subduction: The Sinking of Tectonic Plates - ThoughtCo
    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 Continents are made up of rocks that are too buoyant to be carried much farther than about 100 kilometers deep
  • What Is The Process Of Subduction? - WorldAtlas
    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
  • What is a subduction zone? - Live Science
    A subduction zone is a collision between two of Earth's tectonic plates, where one plate sinks into the mantle underneath the other plate
  • Whats a Subduction Zone? Everyone in the Pacific NW Should Know
    A subduction zone can shake things up — literally These geological features are responsible for some of the most intense earthquakes, volcanic eruptions and tsunamis
  • Subduction zone | Plate Tectonics, Oceanic Crust Volcanism - Britannica
    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
  • Subduction Zone: Definition, Features, Types - Geology In
    A subduction zone is a region of the Earth's crust where two tectonic plates meet, and one plate is forced beneath the other into the mantle This process, called subduction, occurs at convergent boundaries and is a primary mechanism driving plate tectonics, leading to volcanic activity, earthquakes, and mountain formation
  • Convergent Plate Boundaries—Subduction Zones - Geology (U. S. National . . .
    Subduction zones form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust
  • Subduction Zone Science: Definition, Example, And A Simple Explanation
    What Are Subduction Zones? What Do Subduction Zones Create? Conclusion; When an oceanic plate collides with a continental plate, the oceanic plate (being heavier) bends and slides beneath the continental plate When this plate is forced to bend downwards, the process is called subduction
