South Asia

South Asia or Southern Asia is a term used to represent the southern region of the Asian continent, which comprises the sub-Himalayan SAARC countries and, for some authorities, adjoining countries to the west and east. Topographically, it is dominated by the Indian Plate, which rises above sea level as Nepal and northern parts of India situated south of the Himalayas and the Hindu Kush. South Asia is bounded on the south by the Indian Ocean and on land (clockwise, from west) by West Asia, Central Asia, East Asia, and Southeast Asia. The terms "Indian subcontinent" and "South Asia" are sometimes used interchangeably.

The current territories of Afghanistan, Bangladesh, Bhutan, Maldives, Nepal, India, Pakistan, and Sri Lanka form the countries of South Asia. In addition, with deviating definitions based on often substantially different reasons, the British Indian Ocean Territory, Mauritius, and the Tibet Autonomous Region are included as well. South Asia is home to well over one fifth of the world's population, making it both the most populous and the most densely populated geographical region in the world. The South Asian Association for Regional Cooperation(SAARC) is an economic cooperation organisation in the region which was established in 1985 and includes all eight nations comprising South Asia.

Asia

Asia (ⁱ/ˈeɪʒə/ or /ˈeɪʃə/) is the Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres. Asia covers an area of 44,579,000 square kilometers, about 30% of Earth's total land area and 8.7% of the Earth's total surface area. It has historically been home to the world's first modern civilizations and has always hosted the bulk of the planet's human population. Asia is notable for not only overall large size and population, but unusually dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people. The boundaries of Asia are traditionally determined as that of Eurasia, as there is no significant geographical separation between Asia and Europe. The most commonly accepted boundaries place Asia to the east of the Suez Canal, the Ural River, and the Ural Mountains, and south of the Caucasus Mountains and the Caspian and Black Seas. It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean.

South

South is a noun, adjective, or adverb indicating direction or geography. It is one of the four cardinal directions or compass points. South is the polar opposite of north and is perpendicular to east and west.

Etymology

The word south comes from Old English sūþ, from earlier Proto-Germanic *sunþaz ("south"), possibly related to the same Proto-Indo-European root that the word sun derived from.

Navigation

By convention, the bottom side of a map is south, although reversed maps exist that defy this convention. To go south using a compass for navigation, set a bearing or azimuth of 180°. Alternatively, in the Northern Hemisphere outside the tropics, the Sun will be roughly in the south at midday.

South Pole

True south is the direction towards the southern end of the axis about which the earth rotates, called the South Pole. The South Pole is located in Antarctica. Magnetic south is the direction towards the south magnetic pole, some distance away from the south geographic pole.

Roald Amundsen, from Norway, was the first to reach the South Pole, on 14 December 1911, after Ernest Shackleton from the UK was forced to turn back some distance short.
