Description: The Marianas Trench is the deepest point in the ocean. It is located in the western Pacific and reaches a maximum depth of 10,994 meters below sea level. If Mount Everest were dropped into the trench the peak would still be a mile underwater! This trench is formed at a subduction zone as the Pacific and Marina oceanic plates collide. This also creates the volcanic Mariana island. This phenomenon can be used to introduce patterns of landforms in elementary and the plate tectonics in middle and high school.
