The Mariana Trench Is 7 Miles Deep: What’s Down There?

The Trench sits like a crescent-shaped dent in the floor of the Pacific Ocean, extending over 1500 miles long with an average width of around 43 miles and a depth of almost 7 miles (or just under 36,201 feet). It's deeper than Mount Everest (29,037 ft); at that depth, the weight of water above makes the pressure in the Trench around 1000 times higher than it would be on the ground.
