The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 10,994 m (36,070 ft) below sea level. Oceanic trenches are a feature of the Earth's distinctive plate tectonics .
The Sunda Trench, earlier known as and sometimes still indicated as the Java Trench, [1] is an oceanic trench located in the Indian Ocean near Sumatra, formed where the Australian-Capricorn plates subduct under a part of the Eurasian plate. It is 3,200 kilometres (2,000 mi) long with a maximum depth of 7,290 metres (23,920 feet). [2]

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 maximum depth of that ocean is also in the South Sandwich Trench, which was surveyed by the Five Deeps Expedition in early February 2019. The expedition's sonar team identified the deepest point at 60°28.46′S 025°32.32′W / 60.47433°S 25.53867°W / -60.47433; -25.53867 , with a depth of 7,434 metres (24,390 ft) ± 13 ...
The trench is colored in dark blue, extending from central Mexico to Costa Rica in the Pacific Ocean The trench lies at the convergence of the Cocos, Nazca, North American, and Caribbean plates. The Middle America Trench is a major subduction zone, an oceanic trench in the eastern Pacific Ocean off the southwestern coast of Middle America ...
The Kermadec Trench is one of Earth's deepest oceanic trenches, reaching a depth of 10,047 metres (32,963 ft). [3] Formed by the subduction of the Pacific Plate under the Indo-Australian Plate, it runs parallel with and to the east of the Kermadec Ridge and island arc. The Tonga Trench marks the continuation of subduction to the north.
The trench is a result of a convergent plate boundary, where the eastern edge of the oceanic Nazca plate is being subducted beneath the continental South American plate. [1] The trench is also a part of the Chile triple junction, an unusual junction that consists of a mid-oceanic ridge and the Chile Rise being subducted under the South American ...
