What is deep-ocean trench?

A deep-ocean trench is a long, narrow depression in the ocean floor where tectonic plates are being pulled into the Earth's mantle in a process called subduction. These trenches are some of the deepest parts of the ocean and are typically associated with intense seismic activity and volcanic processes.
