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 200 kilometres to the east of the Mariana Islands, in the Western Pacific East of Philippines. It is a crescent-shaped scar in the Earth's crust, and measures about 2,550 km long and 69 km wide on average. It reaches a maximum-known depth of 10,994 metres at a small slot-shaped valley in its floor known as the Challenger Deep, at its southern end, although so
Deepest Part of the Ocean The Challenger Deep in the Mariana Trench is the deepest known location in Earth's oceans.he Mariana Trench is located at a convergent plate boundary. Here two converging plates of oceanic lithosphere collide with one another. At this collision point, one of the plates descends into the mantle. At the line of contact between the two plates the downward flexure forms a trough known as an ocean trench.
