What is the deepest ocean in world?
Challenger Deep in the Mariana Trench is the deepest point in Earth's oceans. The bottom there is 10,924 meters (35,840 feet) 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.
The Mariana Trench in the Pacific Ocean is the deepest known spot in the ocean at 36,200 ft below sea level. (Further down than Mt Everest is up.)
