Marianas Trench

About

The Mariana Trench is the deepest oceanic trench on Earth, located in the western Pacific Ocean, about 200 kilometers (124 mi) east of the Mariana Islands. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,935 ± 6 meters at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. This makes the deepest point of the trench more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest.
