How Deep is the Ocean?

The Challenger Deep (named after the British survey ship Challenger II) is the deepest known part of the Earth’s oceans. Located in the Mariana Trench, just south of Japan, it reaches a depth of over 10,900 meters (nearly 7 miles).  If Mount Everest were placed in the Challenger Deep, its peak would still be a mile underwater!

The Mariana Trench is created by the convergence of two oceanic plates that form a deep trough.  The pressure at the deepest point is 16,000 pounds per square inch, making manned exploration virtually impossible.  It’s for this reason that it’s sometimes said that we know more about the moon than the deepest parts of the ocean.
