Geography of Asia

The Geography of Asia looks at the lands of Asia. Asia is a very big part of the world. It has 58 countries and areas. Asia has many kinds of land, like tall mountains, wide plains, busy cities, and quiet forests. Learning about Asia's geography helps us understand how people, plants, and animals live together in such a large and changing place. The shape and features of Asia affect the weather, the water, and the lives of many people who live there.

Geographical characteristics

Boundary

Main article: Definition and boundaries of Asia

Asia is very large, and its borders can look different depending on where you look. For example, South Asia and West Asia might appear differently on maps. Egypt is usually part of the Middle East but not considered part of Asia, even though most of the Middle East is in Asia.

Asia's borders are clear in some places. The line between Asia and Africa follows the Suez Canal, the Gulf of Suez, the Red Sea, and the Bab-el-Mandeb. The edge of Asia and Europe starts at the eastern Mediterranean and goes through places like the Dardanelles, the Sea of Marmara, the Bosporus, and the Ural River, ending at the Arctic Ocean. The Bering Straits separate Asia from North America. To the southeast, the Malay Peninsula marks the end of mainland Asia, with Indonesia made up of many islands nearby. Australia is a different continent, and the islands northeast of Australia belong to Oceania.

Overall dimensions

Different sources give different numbers for how big Asia is. Some say it's about 44 million square kilometers. Asia stretches from about 77° North to 1° North in latitude and from 26° East to 169° West in longitude. This makes Asia roughly 8,700 kilometers long and 9,700 kilometers wide. Indonesia, with its many islands, adds more land to Asia and stretches its southern reach even further. The exact border between Asia and Australia is still being worked out.

European views of Asia

Geographical or traditional view

Long ago, people in Europe thought of Asia as a big, separate land. They believed the world had three big lands: Europe, Asia, and Africa. Many maps and books still show these three as separate lands.

Hellenic origin

The idea of three lands began in ancient Greece. The Greeks didn’t know much about lands, but they saw differences between islands and big lands. Over time, they talked about places called Asia, Europe, and Libya (a small place near Egypt). They described Asia by its coasts, from the Black Sea around Asia Minor to the Red Sea and India.

Imperial Roman geography

Later, during the time of the Roman Empire, the idea of three lands became stronger. A Roman writer named Ptolemy said lands should be separated by water when possible. He said the Red Sea was the border between Africa (which he called Libya) and Asia, and the Don River was the border between Europe and Asia. His idea of Asia reached almost to today’s Far East, including parts of what is now Russia.

Geologic view

Newer studies of how the Earth moves show that Asia has areas that could be seen as separate lands. Scientists study these lands, called tectonic plates. In strict science, Europe and Asia are part of one big land called Eurasia.

Regional view

When people study Asia, they think about it in different ways. One way is to keep Europe and Asia as separate lands and look closer at places like East Asia, South Asia, and the Middle East. Some people use “land” to mean just a big area in science.

Ethnic view

In everyday talk, especially in Europe and America, the word “Asian” often talks about a person’s background, not where they live. In American English, “Asian” usually means people from East and Southeast Asia, while in British English, it often means people from South Asia. Asia has many different places, like the Indian subcontinent, the Iranian Plateau, and the Arabian Peninsula.

Regions

Further information: Subregion § Asia

Since the 18th century, Asia has been divided into several regions. There is no single agreement on how to use these terms.

The six main regions of Asia are:

• Central Asia: This area includes countries that were once part of a large group of nations, such as Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.
• East Asia: This region includes China, Hong Kong, Japan, Macau, Mongolia, North Korea, South Korea, and Taiwan. It also includes areas like Mainland China and smaller parts such as Inner Mongolia and Tibet.
• North Asia: This is mainly Siberia, which is part of Russia.
• South Asia: This region includes Afghanistan, Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka. It is often called the Indian subcontinent.
• Southeast Asia: This area has countries such as Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam.
• West Asia: This region includes Armenia, Azerbaijan, Bahrain, Georgia, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syria, Turkey, the United Arab Emirates, and Yemen. It is also known as the Middle East or Southwest Asia.

Climate

Main article: Climate of Asia

Asia has many different climates. In the southwest, it is usually dry. The western part of Asia can have big temperature changes from day to night. In the south and east, rains called monsoons come because of big mountains called the Himalayas. These rains bring wet weather in the summer.

The southwest part of Asia is flat and can be very hot in summer and cool in winter. In places like Siberia, it can get extremely cold. Some areas near the Philippines and Japan see strong storms called tropical cyclones. All of Asia is feeling the effects of changing weather patterns.

General data for countries defined as Asian by the UNSD

The United Nations Statistics Division collects information about regions, including Asia. They use a system called United Nations M49 to group countries for statistics. This system helps gather useful information but does not decide political boundaries.

M49 is updated often to match world changes. One tricky part is "Northern Asia," which is not an official region. Russia is considered part of Europe, even though part of it lies in Asia. The United Nations places Russia in Europe, so this issue is not fully solved. The table below shows countries and areas linked to Asia, with notes about special cases and different views on where some countries belong.
