Oceanic trenches are long, but thin and deep cuttings down at the bottom of the ocean's floor, which are located at the subduction of two adjoining tectonic plates. The most prominent of these depressions can be found at the edges of the Pacific Ocean, especially by its western areas.

The deepest and most famous of these trenches is the Mariana Trench, located halfway between Japan and New Guinea, around 11,000 meters in depth. The second in the row, in terms of depth, is the Tonga Trench, located north of New Zealand, next to the small country of Tonga. The Philippine Trench and Kuril–Kamchatka Trench are quite similarly deep, around 10,500 meters, the former lies next to the Philippines, while the latter is way up on the north, next to the Kuril Islands and the Kamchatka Peninsula. The fifth trench that reaches 10,000 meters is the Kermadec Trench, which can be taken as a southern elongation of the deeper Tonga Trench.
