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: -Such destruction (recycling) of crust takes place along convergent boundaries where plates are moving toward each other, and sometimes one plate sinks (is subducted) under another. The location where sinking of a plate occurs is called a subduction zone.
Detailed explanation-3: -At the boundaries of two plates, the heavier oceanic plate sinks below the lighter continental plate in a process that experts call subduction.
