The deepest known point in the ocean is called The Challenger Deep and is located in the Marianas Trench in the Western Pacific. It may seem obvious to state that the ocean is deep but the Marianas Trench takes that term to a whole new level. The bottom of the Challenger Deep is 11,034m deep. It’s so far below the surface of the Pacific that if you placed Mount Everest at the bottom, not only would the peak not stick out of the water, there would actually still be over 1 mile to the surface. That’s seriously deep!
