The Mariana Trench or Marianas Trench is the deepest part of the world's oceans.It is located in the western Pacific Ocean, to the east of the Mariana Islands.he Mariana Trench is part of the Izu-Bonin-Mariana subduction system that forms the boundary between two tectonic plates. In this system, the western edge of one plate, the Pacific Plate, is subducted (i.e., thrust) beneath the smaller Mariana Plate that lies to the west.
The Mariana Trench (or Marianas Trench) is the deepest known submarine trench, and the deepest location in the Earth's crust itself.It is located in the floor of the western North Pacific Ocean, to the east of the Mariana Islands at 11Â° 21' North latitude and 142Â° 12' East longitude, which is near Japan.aking into account its latitude and the Earth's equatorial bulge, this puts it at 6366.4 km from the centre of the Earth. The Arctic ocean, on the other hand, is ~4 km deep, which would put its floor at ~6352.8 km from the Earth's centre, 13.6 km closer.
