Which of the following is found at a subduction zone? (2g, DOK 1) A. a deep ocean trench B. a rift valley C. a mid-ocean ridge D. a canyon

The correct answer is " a deep ocean trench".

Explanation:

Subduction zones are regions of the Earth at which a tectonic plate moved beneath another due to the presence of high gravitational potential energy into the mantle. The age of the ocean floor is greatest in subduction zones because the process of gravitational sink takes place where oceanic crust and lithosphere are old and thick. The ocean floor is also old at regions closest to deep-ocean trenches, the locations with the deepest zones on Earth, because these places also suffer from gravitational sink causing earthquakes and the formation of sea floor volcanoes.
