The outer rim of the trench is at a depth of 2,700 m (8,900 ft) and contains about 600 km 2 (230 sq mi) inside the rim, descending to approximately 5,550 m (18,210 ft) at its greatest depth. The basin floor measures about 220 km 2 (85 sq mi) and is the deepest point in the Arctic Ocean.
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 ...

Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. Oceanic trenches are prominent, long, narrow topographic depressions of the ocean floor. They are typically 50 to 100 kilometers (30 to 60 mi) wide and 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic ...
The Atlantic Ocean and the Arctic Ocean are good examples of active, growing oceanic basins, whereas the Mediterranean Sea is shrinking. The Pacific Ocean is also an active, shrinking oceanic basin, even though it has both spreading ridge and oceanic trenches.
Pictured is a lump of 66-million-year-old vomit found on the Cliffs of Stevns, a geological site on the Danish island of Zealand that is comprised of a 15 km-long fossil-rich coastal cliff.
The Gakkel Ridge (formerly known as the Nansen Cordillera and Arctic Mid-Ocean Ridge) [1] is a mid-oceanic ridge, a divergent tectonic plate boundary between the North American Plate and the Eurasian Plate. [2]
