Location of the Mariana Trench. The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, an average of 124 miles/200km to the east of the Mariana Islands, in the Western Pacific East of Philippines. The trench is about 2,550 kilometres (1,580 mi) long with an average width of 69 kilometres (43 mi).
Ocean trenches are the deepest parts of the ocean, with the Mariana Trench near Guam having the deepest spot on Earth (the Challenger Deep). Most ocean trenches are in the Pacific. The loss of the earth's crust at ocean trenches is made up for by seafloor spreading elsewhere, which is when tectonic plates are pulling apart.
