Indian Sea, body of salt water covering approximately one-fifth of the overall sea area of the globe. It is the smallest, geologically youngest, and physically most intricate of the world's three significant oceans (Pacific, Atlantic, and also Indian). It goes for more than 6,200 miles (10,000 km) between the southerly suggestions of Africa and Australia and, without its minimal seas, has an area of regarding 27,243,000 square miles (70,560,000 square kilometres). The Indian Sea's average deepness is 12,274 feet (3,741 metres), and also its inmost point, in the Sunda Deep of the Java Trench off the southern shore of the island of Java (Indonesia), is 24,442 feet (7,450 metres).
The Indian Sea is bounded by Iran, Pakistan, India, and Bangladesh to the north; the Malay Peninsula, the Sunda Islands of Indonesia, and Australia to the eastern; the Southern Sea to the south; and also Africa as well as the Arabian Peninsula to the west. In the southwest it joins the Atlantic Ocean southern of the southerly pointer of Africa, and also to the east as well as southeast its waters mingle with those of the Pacific Ocean. The inquiry of specifying the nautical limitations of the Indian Sea is complicated as well as continues to be unsettled. The clearest boundary as well as the one most generally agreed upon is that with the Atlantic Sea, which runs from Cape Agulhas, at the southern suggestion of Africa, due southern along the 20 ° E meridian. The boundary with the Pacific Sea to the southeast is normally drawn from South East Cape on the island of Tasmania southern along the 147 ° E meridian.Bass Strait, between Tasmania as well as Australia, is thought about by some to be part of the Indian Ocean and also by others to be part of the Pacific. The northeastern boundary is one of the most tough to define. The one most normally set runs northwest from Cape Londonderry in Australia across the Timor Sea, along the southern coasts of the Lesser Sunda Islands and of Java, and after that throughout the Sunda Strait to the shores of the island of Sumatra. In between Sumatra as well as the Malay Peninsula the border is generally attracted throughout the Singapore Strait.
