What geographic feature is associated with subduction zones?

Subduction is a process when two tectonic plates meet and one of the plates sinks below the level of the other into the mantle of the earth. Geographic features that are located at such "subduction zones" are deep sea ocean trenches, chains of active volcanoes, and places with consistent earthquakes.

Subduction Zones are usually known to be part of the Destructive Plate Boundary. The changes that occur in this boundary.
