An arcing depression, the Mariana Trench stretches for more than 1,580 miles (2,540 km) with a mean width of 43 miles (69 km). The greatest depths are reached in Challenger Deep, a smaller steep-walled valley on the floor of the main trench southwest of Guam.

The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.
Descent, from the beginning of the dive to arrival at the seafloor, took two hours and 37 minutes, almost twice as fast as the descent of Trieste. [41] A Rolex watch, "worn" on the sub's robotic arm, continued to function normally throughout the dive.

31 mar 2021 · The deepest parts of our oceans, the region between 6000 and 11 0000 m depth, is known as the hadal zone, and it represents some of the most active and diverse marine habitat on Earth. Many studies of the hadal zone focus on the conspicuous, gigantic trenches formed by shifting tectonic plates, known as subduction zones.
The Mariana trench lies in the west of the Pacific Ocean, south of Japan. Its depth varies along its 1580-mile length but the deepest point confirmed so far, known as Challenger Deep, reaches a...
