Overview
Asia is the largest continent on Earth by both land area and population. It extends from the Arctic Ocean in the north to the Indian Ocean in the south, and from the Ural region and Middle East in the west to the Pacific Ocean in the east.
Asia contains an extraordinary variety of landscapes, climates, ecosystems, languages, cultures and societies. It includes the highest mountains on Earth, some of the world's largest deserts, vast forests, major river systems and densely populated urban regions.
Geographically, Asia is part of the enormous Eurasian landmass. Europe and Asia are conventionally treated as separate continents, although there is no universally agreed physical boundary between them.
Geography of Asia
Asia has one of the most varied physical geographies on Earth. Its landscape has been shaped by plate tectonics, mountain building, erosion, glaciation, volcanism, rivers and climatic processes.
Major geographical features
- Himalayas
- Tibetan Plateau
- Gobi Desert
- Arabian Desert
- Taklamakan Desert
- West Siberian Plain
- Indo-Gangetic Plain
- Siberian forests
- Arabian Peninsula
- Malay Archipelago
Asia also contains enormous coastal regions and many island groups, particularly in East and Southeast Asia.
Regions of Asia
Asia can be divided into several broad geographical and cultural regions. Different organisations use somewhat different regional classifications.
East Asia
East Asia includes China, Japan, the Korean Peninsula and Mongolia, together with surrounding territories and island regions. It contains some of the world's largest cities and major industrial economies.
South Asia
South Asia includes India, Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka and the Maldives, with Afghanistan also often included in regional classifications. The Himalayas and monsoon system are major geographical influences.
Southeast Asia
Southeast Asia contains mainland and maritime regions. It includes countries such as Vietnam, Thailand, Indonesia, Malaysia, the Philippines and Singapore.
Central Asia
Central Asia consists principally of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. The region contains extensive steppe, deserts and major mountain systems.
West Asia
West Asia includes the Arabian Peninsula, the Levant, Anatolia, the Caucasus and surrounding regions. It contains important deserts, mountain ranges and inland seas.
North Asia
North Asia is dominated geographically by Siberia, the vast northern region of Russia. It includes extensive boreal forests, tundra and major river systems.
Countries of Asia
Asia contains approximately 49 countries under commonly used geographical classifications, although the exact number varies depending on definitions and the treatment of transcontinental states.
| Region | Examples of Countries |
|---|---|
| East Asia | China, Japan, Mongolia, North Korea, South Korea |
| South Asia | India, Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka, Maldives |

The Tibetan Plateau
The Tibetan Plateau is one of the world's largest and highest elevated regions. It strongly influences Asian atmospheric circulation and the development of the Asian monsoon.
Rivers and Lakes
Asia contains some of the world's greatest river systems. Many support enormous populations and have played central roles in the development of agriculture and civilisation.
| River | Region | Importance |
|---|---|---|
| Yangtze | China | Longest river in Asia |
| Yellow River | China | Historically important to Chinese civilisation |
| Ganges | India and Bangladesh | Major South Asian river system |

| Ob-Irtysh | Siberia | Major river system draining into the Arctic Ocean |
Major lakes
- Caspian Sea
- Lake Baikal
- Aral Sea
- Lake Balkhash
- Lake Issyk-Kul
Lake Baikal is particularly significant because it is the world's deepest freshwater lake and contains a very large volume of liquid freshwater.
Deserts of Asia
Asia contains some of the world's largest and most important deserts. These dry environments are distributed across the Middle East, Central Asia and East Asia.
| Desert | Region |
|---|---|
| Gobi Desert | Mongolia and China |
| Arabian Desert | Arabian Peninsula |
| Taklamakan Desert | Western China |
| Thar Desert | India and Pakistan |

Climate
Asia contains almost every major climate type found on Earth. Its enormous size and wide range of latitudes produce extraordinary climatic diversity.
Arctic climate
Northern Siberia contains some of the coldest inhabited regions on Earth and includes extensive tundra environments.
Temperate climate
Large parts of East Asia, Central Asia and Europe-facing regions of Asia experience temperate climates.
Monsoon climate
South and Southeast Asia are strongly influenced by seasonal monsoon circulation. Monsoon rainfall is essential to agriculture across large parts of the region.
Desert climate
The Middle East and Central Asia contain extensive arid and semi-arid environments.
Tropical climate
Tropical climates occur in southern and southeastern regions, including parts of India, Southeast Asia and the Indonesian archipelago.
The Asian Monsoon
The Asian monsoon is one of the most important atmospheric circulation systems on Earth. Seasonal differences in heating between the Asian landmass and surrounding oceans contribute to major changes in wind direction and precipitation.
The monsoon provides essential rainfall for agriculture and freshwater supplies but can also produce floods, landslides and other hazards.
Asian Ecosystems
Asia contains an enormous range of ecosystems, from Arctic tundra and Siberian taiga to tropical rainforests and coral reefs.
- Siberian boreal forests
- Central Asian steppes
- Himalayan mountain ecosystems
- Chinese temperate forests
- Southeast Asian rainforests
- Indian tropical forests
- Arabian deserts
- Mangrove ecosystems
- Coral reefs
Wildlife of Asia
Asia contains many iconic and endangered species adapted to a remarkable range of habitats.
- Asian elephant
- Bengal tiger
- Snow leopard
- Giant panda
- Orangutan
- Komodo dragon
- Yak
- Red panda
- Saiga antelope
- Arabian oryx
History of Asia
