Asia is a continent of desert cities, mountain kingdoms, great river valleys and tropical islands, from the Arabian Peninsula in the west to Japan and Indonesia in the east.
The best-known wonders of Asia include the Great Wall of China, the Forbidden City in Beijing, the Taj Mahal in Agra and the rock-cut city of Petra in Jordan. The great temples of Asia include Angkor Wat in Cambodia, the Temples of Bagan in Myanmar and Borobudur in Indonesia.
Natural wonders of Asia range from Mount Everest in the Himalayas to the limestone islands of Ha Long Bay in Vietnam. The Hanging Gardens of Babylon, a lost wonder, were described by ancient writers as standing in what is now Iraq.
Where is Asia?
Asia covers the eastern four-fifths of Eurasia, the giant landmass that Asia shares with Europe.
The Arctic Ocean borders Asia to the north, the Pacific Ocean to the east, and the Indian Ocean to the south. To the southwest, Asia meets the Red Sea, the Mediterranean Sea and the Black Sea. On its western side, Asia joins Europe on land.
The Bering Strait separates Asia from North America in the far northeast. In the southwest, the Suez Canal is generally agreed to mark the border between Asia and Africa. To the southeast, the seas and straits between the Indian and Pacific oceans separate Asia from Australia.
Is Asia a country?
No, Asia is not a country. Asia is a continent, made up of many separate countries.
The origin of the name Asia is uncertain. The ancient Greeks used the name Asia for the lands east of Greece. One explanation links the name Asia to the Assyrian word asu, meaning "east".
Another explanation traces the name Asia to a local name for the plains of Ephesus, in what is now western Turkey. The Greeks and Romans later used the name for all of Anatolia, and then for the known world east of the Mediterranean Sea. Western explorers extended the name to the whole continent when they reached South and East Asia in the early modern period.
Is Asia the largest continent?
Yes, Asia is the largest continent on Earth, by both area and population.
Asia is 1,385,000 km² (535,000 sq mi) larger than Africa, the second-largest continent, on United Nations figures.
The UN counts all of Russia as part of Europe, not Asia. With Asian Russia included, Asia covers 44,614,000 km² (17,226,200 sq mi), about one-third of Earth's land surface, according to Britannica.
Asia is also the most populous continent, home to about three in every five people in the world.
How many countries are in Asia?
There are 48 countries in Asia, according to the United Nations list of countries by region.
Forty-seven of the 48 Asian countries are UN member states. The 48th is the State of Palestine, which has non-member observer status at the United Nations.
Hong Kong and Macao, two special administrative regions of China, appear as separate areas on the UN list for Asia. Turkey, Cyprus, Georgia, Armenia and Azerbaijan are in Asia on the UN list, under Western Asia.
Where does Europe end and Asia begin?
Europe ends and Asia begins along the Ural Mountains, the Caspian Sea, and the Black Sea.
The land boundary between Europe and Asia is a matter of agreement. Geographers have drawn the line between Europe and Asia in different places through history.
On the line most geographers use, the boundary runs south from the Arctic Ocean along the Ural Mountains, then southwest along the Emba River to the northern shore of the Caspian Sea.
West of the Caspian Sea, the Europe and Asia boundary follows the Kuma-Manych Depression, a long lowland, to the Sea of Azov and the Kerch Strait of the Black Sea. The Caucasus Mountains, between the Black Sea and the Caspian Sea, are in Asia on this line.
At the western tip of Asia, two narrow straits, the Bosporus and the Dardanelles, separate Anatolia in Asia from the Balkan Peninsula in Europe.
