Mariana Trench

The Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest trench in the world. It is a crescent-shaped trough in the Earth's crust averaging about 2,550 km (1,580 mi) long and 69 km (43 mi) wide. The maximum known depth is 10,984 metres (36,037 ft) (± 25 metres [82 ft]) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep

Challenger Deep

The Challenger Deep is the deepest known point in the Earth's seabed hydrosphere (the oceans), with a depth of 10,898 to 10,928 m (35,755 to 35,853 ft) by direct measurement from submersibles and slightly more by sonar bathymetry. It is located in the Pacific Ocean, at the southern end of the Mariana Trench near the Mariana Islands group. The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.
