Nature and environment - Seas and waters - Challenger Deep
Approximately how deep is Challenger Deep, the deepest known point in the world's oceans?
Correct!
Challenger Deep lies in the Mariana Trench in the western Pacific and is the deepest known point in the world's oceans. Modern measurements put its depth at approximately 10,935 meters below sea level. If Mount Everest, at nearly 8,849 meters, were placed there, its summit would still be more than two kilometers below the surface. By contrast, the average depth of the world's oceans is about 3,682 meters.
