An oceanic trench is a deep, narrow depression in the ocean floor, typically found at the convergence of tectonic plates. These trenches form where one tectonic plate is being subducted under another, a process driven by the dynamics of plate tectonics. Oceanic trenches are the deepest parts of the Earth's oceans and can reach depths of over 10,000 meters (about 32,800 feet).
