GEOLOGY

Detailed explanation-1: -A subduction zone is a tectonic feature on the Earth’s surface where one plate slides underneath another at a converging plate boundary. Subduction zones are solely located in oceanic basins. The oceanic plate can converge under either another oceanic plate or a continental plate.

Detailed explanation-2: -(A) A subduction zone forms when oceanic crust slides under continental crust. Fig. 7.24. (B) The collision of two continental crusts interrupts the subduction process and forms a new mountain chain.

Detailed explanation-3: -When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.

Detailed explanation-4: -Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.

Detailed explanation-5: -A subduction zone is a region in which a portion of a tectonic plate sinks beneath another plate into the Earth’s interior. Subduction zones are defined by deep oceanic trenches, lines of volcanoes parallel to the trenches, and zones of large earthquakes that extend from the trenches landward.
