Asia is the axial and eastern allotment of Eurasia, absolute about fifty countries. It has an area, including islands, of almost 789,694,700 km². Asia is abutting to Africa by the Isthmus of Suez and to Europe by a continued bound about afterward the Ural Mountains.
Medieval Europeans advised Asia as a continent, a audible landmass. The European abstraction of the three continents in the Old World goes aback to classical antique with the ancestry of the chat abiding in the age-old Abreast and Middle East. The bound amid Asia and Africa is the isthmus of Suez and the Red Sea. The abuttals amid Asia and Europe is frequently believed to run through the Dardanelles, the Sea of Marmara, the Bosporus, the Black Sea, the Caucasus Mountains, the Caspian Sea, the Ural River to its source, and the Ural Mountains to the Kara Sea abreast Kara, Russia. However, avant-garde assay of the admeasurement of Africa and Asia fabricated this analogue rather anachronistic, abnormally in the case of Asia, which would accept several regions that would be advised audible landmasses if these belief were acclimated (for example, South Asia and East Asia).
Geologists and concrete geographers no best accede Europe and Asia to be abstracted continents. It is either authentic in agreement of geological landmasses (physical geography) or tectonic plates (geology). In the above case, Europe is a western peninsula of Eurasia or the Africa-Eurasia landmass. In the latter, Europe and Asia are genitalia of the Eurasian plate, which excludes the Arabian and Indian tectonic plates.
In animal geography, there are two schools of thought. One academy follows actual assemblage and treats Europe and Asia as altered continents, allocation Europe, East Asia (the Orient), South Asia (British India), and the Middle East (Arabia and Persia) as specific regions for added abundant analysis. The added schools agree the chat "continent" in agreement of bounded arena back apropos to Europe, and use the appellation "region" to call Asia in agreement of concrete geography. It is acceptable more accepted to acting the appellation "region" for "continent" because in linguistic terms, "continent" implies a audible landmass.

Asia is the world's bigger and best crawling continent, amid primarily in the eastern and chill hemispheres. It covers 8.6% of the Earth's absolute apparent breadth (or 29.9% of its acreage area) and with about 4 billion people, it hosts 60% of the world's accustomed animal population. During the 20th aeon Asia's citizenry about quadrupled.
Asia is commonly authentic as allotment of the landmass of Eurasia—with the western allocation of the closing active by Europe—located to the east of the Suez Canal, east of the Ural Mountains and south of the Caucasus Mountains (or the Kuma-Manych Depression) and the Caspian and Black Seas. It is belted on the east by the Pacific Ocean, on the south by the Indian Ocean and on the chill by the Chill Ocean. Given its admeasurement and diversity, Asia—a toponym dating aback to classical antiquity—is added a cultural abstraction accumulation a cardinal of regions and peoples than a constant concrete article (see Subregions of Asia, Asian people). The abundance of Asia differs actual broadly amid and aural its regions, due to its all-inclusive admeasurement and huge ambit of altered indigenous groups, cultures, environments, actual ties and government systems.
The aboriginal acumen amid Europe and Asia was fabricated by the age-old Greeks. They acclimated the Aegean Sea, the Dardanelles, the Sea of Marmara, the Bosporus, the Black Sea, the Kerch Strait, and the Sea of Azov as the bound amid Asia and Europe. The Nile was acclimated as the bound amid Asia and Africa (then alleged Libya), although some greek geographers appropriate the Red Sea would anatomy a bigger boundary. However the Nile was usually advised the bound until the 15th century, back the abuttals was afflicted to the Persian Gulf, the Red Sea, and the Isthmus of Suez. At the aforementioned time, the bound of amid Asia and Europe became an issue, as the old boundaries did not extend to the chill as ahead thought. In the eighteenth aeon the Ural mountains were aboriginal appropriate as the border, and by the nineteenth aeon this bound had become the accustomed divide. To affix this to the antecedent divide, the bound was continued southwards from the mountains to the Ural river, afterwards which it anesthetized through the Caspian Sea and beyond the acme of the Caucasus, basic the broadly accustomed abuttals acclimated today. The bound amid Asia and Oceania is placed about in the Malay archipelago, with islands acceptance to Indonesia usually included in Asia, including the western bisected of New Guinea.
Some contentions about the borders still exist. Asia is the bigger and best culturally assorted of the continents in the seven-continent system, and does not absolutely bout with accepted Asian cultural boundaries. Some definitions exclude Turkey, the Middle East, Central Asia and Russia while alone because the Far East, Southeast Asia and the Indian subcontinent to compose Asia, abnormally in the United States afterwards World War II. The appellation is sometimes acclimated added almost in advertence to the Asia-Pacific region, which does not accommodate the Middle East, South Asia or Russia, but does accommodate islands in the Pacific Ocean—a cardinal of which may additionally be advised allotment of Australasia or Oceania, although Pacific Islanders are not advised Asian.
Some geographers do not accede Asia and Europe to be abstracted continents, as there is no analytic concrete break amid them. For example, Sir Barry Cunliffe, the emeritus assistant of European archeology at Oxford, argues that Europe has been geographically and culturally alone "the western abscess of the abstemious of Asia." Geographically, Asia is the above eastern basic of the abstemious of Eurasia with Europe actuality a northwestern peninsula of the landmass–or of Afro-Eurasia: geologically, Asia, Europe and Africa comprise a distinct connected landmass (save the Suez Canal) and allotment a accepted continental shelf. Almost all of Europe and best of Asia sit aloft the Eurasian Plate, adjoined on the south by the Arabian and Indian Plate and with the easternmost allotment of Siberia (east of the Cherskiy Range) on the Chill American Plate.
