            Challenger Deep in the Mariana Trench near the Mariana Islands east of the Philippine Sea is the deepest point in Earth's oceans. The bottom there is 10,924 meters (35,840 feet or almost seven miles) below sea level. If Mount Everest, the highest mountain on Earth, were placed at this location it would be covered by over one mile of water. The Challenger Deep is named after the British survey ship Challenger II, which discovered this deepest location in 1951.
