"While the average land elevation is 2,755 feet/840 m, the average depth of the ocean is 12,238 feet/3,730 m. The deepest part is the Marianas Trench in an area called Challenger Deep, where it?s 35,802 feet/10,912 m to the bottom, a depth that could completely submerge Mount Everest by more than 8,000 feet/2,438 m.
