what is the deepest oceans in the world
Mariana Trench The Mariana Trench or Marianas Trench[1] is the deepest part of the world's oceans. It is located in the western Pacific Ocean, an average of 200 kilometres (124 mi) 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 (1,580 mi) long and 69 km (43 mi) wide on average. It reaches a maximum-known depth of 10,994 metres (36,070 ft) (± 40 metres [130 ft]) at a small slot-shaped valley in its floor known as the Challenger Deep, at its southern end,[2] although some unrepeated measurements place the deepest portion at 11,034 metres (36,201 ft).[3] For comparison: if Mount Everest were dropped into the trench at this point, its peak would still be over 2 kilometres (1.2 mi) underwater.[a] In 2009, the Marianas Trench was established as a United States National Monument.[5]
Arabian Sea The Arabian Sea is a region of the northern Indian Ocean bounded on the northeast and east by the Indian Peninsula on the west by Somalia and the Arabian Peninsula, on the north by Pakistan and Iran and on the South by the Maldives. Historically the sea has been known by other names including the Erythraean Sea and the Persian Sea. Its total area is 3,862,000 km2 (1,491,000 sq mi) and its maximum depth is 4,652 metres (15,262 ft). The Gulf of Aden is in the southwest, connecting the Arabian Sea to the Red Sea through the strait of Bab-el-Mandeb, and the Gulf of Oman is in the northwest, connecting it to the Persian Gulf.
Indian Ocean The Indian Ocean is the third largest of the world's oceanic divisions, covering 70,560,000 km2 (27,240,000 sq mi) (approximately 20% of the water on the Earth's surface).[1] It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica.[2] It is named after India.[3][4]
Mariana Trench The Mariana Trench or Marianas Trench[1] is located in the western Pacific Ocean approximately 200 kilometres (124 mi) east of the Mariana Islands, and has the deepest natural point in the world. It is a crescent-shaped trough in the Earth's crust averaging about 2,550 km (1,580 mi) long and 69 km (43 mi) wide. The maximum known depth is 10,994 metres (36,070 ft) (± 40 metres [130 ft]) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep.[2] However, some unrepeated measurements place the deepest portion at 11,034 metres (36,201 ft).[3] For comparison: if Mount Everest were dropped into the trench at this point, its peak would still be over 2 kilometres (1.2 mi) under water.[a]
