The Mariana Trench is a crescent-shaped scar in the Earth’s crust that measures more than 1,500 miles long and 43 miles wide on average.

The distance between the surface of the ocean and the trench’s deepest point, the Challenger Deep, is nearly 7 miles.

If Mount Everest were dropped into the Mariana Trench, its peak would still be more than a mile underwater.
