What are the deepest trenches?

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 oceanic trench on Earth.

How deep is the Japanese trench?

The deepest depth in the Japan Trench is 8020m . These trenches also mark the boundary where the Pacific Plate sinks under other plates (Japan Oceanographic Data Center, 1985).

How deep is the Tonga Trench?

10,882 m
Its deepest point is 10,882 m, a site known as the Horizon Deep, and it is separated from the neighboring Kermadec Trench in the south by the Tonga Platform, a sill that rises to approximately 5.5 km in depth (Fig.

How deep in the ocean is a trench?

Oceanic trenches typically extend 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level. Oceanic lithosphere moves into trenches at a global rate of about 3 km 2 /yr.

What is the trench morphology of the Chile Trench?

The central Chile segment of the trench is moderately sedimented, with sediments onlapping onto pelagic sediments or ocean basement of the subducting slab, but the trench morphology is still clearly discernible. The southern Chile segment of the trench is fully sedimented, to the point where the outer rise and slope are no longer discernible.

What is the physiography of a trench?

Trenches are centerpieces of the distinctive physiography of a convergent plate margin. Transects across trenches yield asymmetric profiles, with relatively gentle (~5°) outer (seaward) slopes and a steeper (~10–16°) inner (landward) slopes.
