The Indian Ocean is the third largest of the world's oceanic divisions, covering about 20% of the water on the Earth's surface. An ocean (from Greek, ''Okeanos'' (Oceanus) is a major body of saline water, and a principal component of the Hydrosphere. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 It is bounded on the north by Asia (including the Indian subcontinent, after which it is named); on the west by Africa; on the east by Indochina, the Sunda Islands, and Australia; and on the south by the Southern Ocean (or, traditionally, by Antarctica). This article deals with the geophysical region in Asia For geopolitical treatments see South Asia. Indochina, or the Indochinese Peninsula, is a region in Southeast Asia. The Sunda Islands are a group of Islands in the western part of the Malay Archipelago. For a topic outline on this subject see List of basic Australia topics. The Southern Ocean, also known as the Great Southern Ocean, the Antarctic Ocean and the South Polar Ocean, comprises the southernmost waters of One component of the all-encompassing World Ocean, the Indian Ocean is delineated from the Atlantic Ocean by the 20° east meridian running south from Cape Agulhas,[1] and from the Pacific by the 147° east meridian. The World Ocean, world ocean, or global ocean is the interconnected system of the Earth 's Oceanic (or marine) Waters This article is about the geographical concept For other uses of the word see Meridian. Cape Agulhas ( Portuguese: Cabo das Agulhas, "Cape of Needles" is the geographic southern tip of the African Continent The Pacific Ocean is the largest of the Earth 's Oceanic divisions The northernmost extent of the Indian Ocean is approximately 30° north latitude in the Persian Gulf and, thus, has asymmetric ocean circulation. Latitude, usually denoted symbolically by the Greek letter phi ( Φ) gives the location of a place on Earth (or other planetary body north or south of the The Persian Gulf, in the Southwest Asian region is an extension of the This ocean is nearly 10,000 kilometres (6,200 mi) wide at the southern tips of Africa and Australia; its area is 73,556,000 square kilometres (32. 1 mi), including the Red Sea and the Persian Gulf. The Red Sea is a Salt water Inlet of the Indian Ocean between Africa and Asia. The Persian Gulf, in the Southwest Asian region is an extension of the
The ocean's volume is estimated to be 292,131,000 cubic kilometers (70,086,000 mi³). Small islands dot the continental rims. Island nations within the ocean are Madagascar (formerly Malagasy Republic), the world's fourth largest island; Comoros; Seychelles; Maldives; Mauritius; and Sri Lanka.

The Republic of Indonesia ( (Republik Indonesia is a Country in Southeast Asia. The ocean's importance as a transit route between Asia and Africa has made it a scene of conflict. Because of its size, however, no nation had successfully dominated most of it until the early 1800s when the United Kingdom controlled much of the surrounding land. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located After the decline of the British Empire, the ocean has been dominated by India and Australia. The British Empire was the largest empire in history and for over a century was the foremost global power.

The African, Indian, and Antarctic crustal plates converge in the Indian Ocean. Their junctures are marked by branches of the Mid-Oceanic Ridge forming an inverted Y, with the stem running south from the edge of the continental shelf near Mumbai, India. The continental shelf is the extended perimeter of each Continent and associated Coastal plain, which is covered during interglacial periods such Mumbai ( Marathi:,, IPA: formerly Bombay, is the capital of the Indian state of Maharashtra and the financial India, officially the Republic of India (भारत गणराज्य inc-Latn Bhārat Gaṇarājya; see also other Indian languages) is a country The eastern, western, and southern basins thus formed are subdivided into smaller basins by ridges. The ocean's continental shelves are narrow, averaging 200 kilometres (125 mi) in width. An exception is found off Australia's western coast, where the shelf width exceeds 1,000 kilometres (600 mi). The average depth of the ocean is 3,890 metres (12,760 ft). Its deepest point, is in the Diamantina Deep close to the coast of south west Western Australia. Diamantina Deep Is the deepest point of the Indian Ocean and is located in the Diamantina Trench south west of Perth Western Australia. Western Australia is a state occupying the entire western third of the Australian continent. North of 50° south latitude, 86% of the main basin is covered by pelagic sediments, of which more than half is globigerina ooze. Any water in the sea that is not close to the bottom is in the pelagic zone. The Globigerinida are a common group of Foraminiferans that are found as marine Plankton (other groups are primarily benthic The remaining 14% is layered with terrigenous sediments. In Oceanography, terrigenous Sediments are those derived from the erosion of rocks on land that is that are derived from terrestrial environments Glacial outwash dominates the extreme southern latitudes.

The climate north of the equator is affected by a monsoon or tornado wind system. The equator (sometimes referred to colloquially as "the Line") is the intersection of the Earth 's surface with the plane perpendicular to the A monsoon is a seasonal prevailing wind which lasts for several months A tornado is a violent rotating column of air which is in contact with both the surface of the earth and a Cumulonimbus cloud or in rare cases the base of a Cumulus Strong north-east winds blow from October until April; from May until October south and west winds prevail. In the Arabian Sea the violent monsoon brings rain to the Indian subcontinent. The Arabian Sea ( Arabic: بحر العرب transliterated: Baḥr al-'Arab Sanskrit: सिन्धु सागर transliterated: In the southern hemisphere the winds generally are milder, but summer storms near Mauritius can be severe. When the monsoon winds change, cyclones sometimes strike the shores of the Arabian Sea and the Bay of Bengal. The Bay of Bengal is a bay that forms the northeastern part of the Indian Ocean. The Indian Ocean is the warmest ocean in the world.
Among the few large rivers flowing into the Indian Ocean are the Zambezi, Shatt al-Arab, Indus, Ganges, Brahmaputra, Juba and Ayeyarwady River. Bathymetry is the underwater equivalent to Hypsometry. The name comes from Greek βαθυς deep, and μετρον measure. The Zambezi (also spelled Zambesi) is the fourth-longest River in Africa and the largest flowing into the Indian Ocean from Africa The Indus River { Sanskrit: सिन्धु Sindhu; Urdu: urd {{Nastaliq سندھ}} Sindh; Sindhi: snd The Ganges (ˈgænʤiːz also Ganga, Devanāgarī: hi गंगा in most Indian languages) is the major river in the Indian subcontinent The Brahmaputra, also called Tsangpo-Brahmaputra is a Trans-boundary river and one of the major Rivers of Asia. The Ayeyarwady River or Irrawaddy River ( is a River that flows from north to south of Burma (Myanmar Currents are mainly controlled by the monsoon. Two large circular currents, one in the northern hemisphere flowing clockwise and one south of the equator moving anticlockwise, constitute the dominant flow pattern. During the winter monsoon, however, currents in the north are reversed. Deep water circulation is controlled primarily by inflows from the Atlantic Ocean, the Red Sea, and Antarctic currents. The Red Sea is a Salt water Inlet of the Indian Ocean between Africa and Asia. North of 20° south latitude the minimum surface temperature is 22 °C (72 °F), exceeding 28 °C (82 °F) to the east. Southward of 40° south latitude, temperatures drop quickly. Surface water salinity ranges from 32 to 37 parts per 1000, the highest occurring in the Arabian Sea and in a belt between southern Africa and south-western Australia. Salinity is the Saltiness or dissolved salt content of a body of Water. Pack ice and icebergs are found throughout the year south of about 65° south latitude. The average northern limit of icebergs is 45° south latitude.
The Indian Ocean provides major sea routes connecting the Middle East, Africa, and East Asia with Europe and the Americas. The Middle East is a Subcontinent with no clear boundaries often used as a synonym to Near East, in opposition to Far East.

The Indian Ocean is far calmer and thus opened to trade earlier than the Atlantic or Pacific Oceans. The Pacific Ocean is the largest of the Earth 's Oceanic divisions The powerful monsoons also meant ships could easily sail west early in the season, then wait a few months and return eastwards. This allowed Indonesian peoples to cross the Indian Ocean to settle in Madagascar. The Republic of Indonesia ( (Republik Indonesia is a Country in Southeast Asia.

But the small nation was unable to support such a vast project, and they were replaced in the mid-17th century by other European powers. The Dutch East India Company (1602-1798) sought control of trade with the East across the Indian Ocean.
