Asia is Earth's largest and most populous continent, located primarily in the eastern and northern
hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. 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. The continent, which has long been home to the majority of the
human population[3][not in citation given], was the site of many of the first civilizations. Asia is notable for
not only its overall large size and population, but also dense and large settlements as well as vast
barely populated regions within the continent of 4.4 billion people.
In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian
Ocean and on the north by the Arctic Ocean. The western boundary with Europe is a historical
and cultural construct, as there is no clear physical and geographical separation between them.
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.[4]
China and India alternated in being the largest economies in the world from 1 to 1800 A.D.
China was a major economic power and attracted many to the east,[5][6][7][8] and for many the
legendary wealth and prosperity of the ancient culture of India personified Asia,[9] attracting
European commerce, exploration and colonialism. The accidental discovery of America by
Columbus in search for India demonstrates this deep fascination. The Silk Road became the main
East-West trading route in the Asian hitherland while the Straits of Malacca stood as a major sea
route. Asia has exhibited economic dynamism (particularly East Asia) as well as robust
population growth during the 20th century, but overall population growth has since fallen.[10] Asia
was the birthplace of most of the world's mainstream religions including Christianity, Islam,
Judaism, Hinduism, Buddhism, Confucianism, Taoism (or Daoism), Jainism, Sikhism,
Zoroastranism, as well as many other religions.
Given its size and diversity, the concept of Asiaa name dating back to classical antiquitymay
actually have more to do with human geography than physical geography.[11] Asia varies greatly
across and within its regions with regard to ethnic groups, cultures, environments, economics,
historical ties and government systems. It also has a mix of many different climates ranging from
the equatorial south via the hot desert in the Middle East, temperate areas in the east and the
extremely continental centre to vast subarctic and polar areas in Siberia.
