INDIAN GEOGRAPHY

Detailed explanation-1: -Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex.

Detailed explanation-2: -When tectonic plates converge, one plate slides beneath the other plate, or subducts, descending into the Earth’s mantle at rates of 2-8 centimeters (1–3 inches) per year.

Detailed explanation-3: -Subduction is a significant geological process involving plate tectonics. The product of convergent boundaries, subduction involves the movement of an oceanic plate into the mantle where it meets a continental or another oceanic plate. The area where subduction occurs is called a subduction zone.

Detailed explanation-4: -There, usually the older, colder, and therefore denser plate sinks below another plate. Continental plates mostly consists of lighter material and can at most be partially subducted. The geodynamic process of one plate sliding beneath another occurs along deep-sea trenches and is called subduction.

Detailed explanation-5: -Subduction zone: the collision site The process begins as two continents (different bits of continental crust), separated across a tract of ocean (and oceanic crust), approach each other, while the oceanic crust is slowly, consumed at a subduction zone.
