Question

At a(n) __________ _______________ ______________ where the denser oceanic crust is recycled back into the mantle, a physical feature called a(n) deep ocean trench is typical.

A) Volcanic eruptions
B) Subduction
C) Plate divergence
D) Crustal uplift

Answer 1

At a subduction zone, a deep ocean trench is typical when the denser oceanic crust is recycled back into the mantle. This occurs when one tectonic plate is forced beneath another. An example of this is the deep Japan trench along the coast of Asia.

Step-by-step explanation:

At a subduction zone, where the denser oceanic crust is recycled back into the mantle, a physical feature called a deep ocean trench is typical. Subduction occurs when one tectonic plate is forced beneath another. As the oceanic plate descends into the mantle, it creates an ocean trench. A well-known example is the deep Japan trench along the coast of Asia.
