Asia, the largest of the continents; it occupies about 30 per cent of the earth's land area. Asia is also the most populous continent, holding approximately 60 per cent of the world's population. Yet some two-thirds of the continent is either too dry or too cold to support anything but a sparse population. An outstanding feature of this huge continent is diversity—in physical features and in the economic, political, and cultural ways of the people.

Facts in brief about Asia

Most of the early centers of civilization were in Asia, mainly in the Tigris and Euphrates valleys, the valley of the Indus, and northern China. Archeological evidence indicates that cultivation of crops and domestication of animals began in these areas. The continent is also the original home of all the great religions of the modern world.

Asia and Europe are not separated by an ocean or strait but form a single landmass, called Eurasia. The dividing line between the two continents is usually considered to run down the Ural Mountains and Ural River to the Caspian Sea and then across the Caucasus Mountains. At the Isthmus of Suez, Asia connects with Africa. North America lies within 60 miles (97 km) of Asia at the Bering Strait.
