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.

The Mariana Trench is the deepest known submarine trench, and the deepest location in the Earth's crust itself. [38] It is a subduction zone where the Pacific Plate is being subducted under the Mariana Plate. [3] At the deepest point, the trench is nearly 11,000 m deep (almost 36,000 feet).
It is apparently the top predator along certain stretches of the Mariana Trench, feeding on tiny crustaceans in a deep-water habitat with few larger predators. [4] Pseudoliparis swirei are abundant in their deep-sea habitat and lay relatively large eggs that are almost 1 cm (0.4 in) in diameter.
The Mariana Trench is the deepest point on Earth, void of light with the pressure of 48 jumbo jets. Yet life finds a way to survive. Very weird life.
Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate .
The islands were formed by the subduction of the Pacific Plate under the Mariana Plate, and the Marianas Trench, the world's deepest, lies immediately east of the islands. The nine northern islands are volcanic and relatively young; Farallon de Pájaros , the northernmost, is an active stratovolcano .
