The trench is continuous, but has different names for different sections: Hikurangi Trough, the Kermadec Trench and the Tonga Trench. The Tonga Trench is the second deepest trench in the world at about 10,800 m, with the deepest point, Horizon Deep, being the deepest point in the Southern Hemisphere and the second deepest point in the world ...
The Tonga Trench constitutes the northern half of the Tonga-Kermadec subduction system, which extends 2,550 km (1,580 mi) between New Zealand and Tonga. [1] The Tonga Trench is an oceanic trench located in the southwestern Pacific Ocean. It is the deepest trench in the Southern hemisphere and the second deepest on Earth after the Mariana Trench.
The second-deepest fish, the hadal snailfish Notoliparis kermadecensis, is endemic to the trench and occupies a very limited depth range, 6,472 to 7,561 m (21,234 to 24,806 ft). [ 7 ] A species of pearlfish , Echiodon neotes , has been caught in the Kermadec Trench at a depth of 8,200–8,300 m (26,900–27,200 ft).
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.
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 .
Litke Deep (Russian: Жёлоб Ли́тке) is [1] [2] an oceanic trench in the Arctic Ocean. The deepest point, also referred to as Litke Deep, is 5,449 m (17,877 ft) below sea level . It is the closest point of the upper surface of Earth's lithosphere to Earth's center , with Challenger Deep being 14.7268 km (9.2 mi) further from Earth's ...
