West Asia

geography Maturity 7-9 Next article →

West Asia is the westernmost region of the Asian continent. It is a large area that connects different parts of the world. Most academics and United Nations bodies define it as a specific subregion. This area includes Anatolia, the Arabian Peninsula, Iran, and Mesopotamia. It also contains the Armenian highlands, the Levant, and the island of Cyprus. The Sinai Peninsula and the South Caucasus are also part of this region.

Geography defines the boundaries of West Asia. The region is separated from Africa by the Isthmus of Suez in Egypt. To the north and northwest, the Turkish Straits and the Greater Caucasus watershed separate it from Europe. Central Asia lies to the northeast, while South Asia is to the east. Twelve different seas surround the region. These include the Aegean Sea, the Black Sea, and the Caspian Sea. Other surrounding waters are the Persian Gulf, the Arabian Sea, and the Mediterranean Sea. The Red Sea and the Gulf of Aden also border the area.

Defining West Asia can be complicated because different groups use different rules. Many people use the term "Middle East" instead. However, "Middle East" is a political term created by Western geographers. West Asia is a more consistent geographical term. The two terms do not mean the exact same thing. For example, West Asia excludes most of Egypt and northwestern Turkey. Yet, the Middle East includes those specific areas. Different organizations also disagree on which countries belong in West Asia. The Food and Agriculture Organization includes Afghanistan, but the World Geographical Scheme for Recording Plant Distributions excludes it.

The physical landscape of West Asia is very diverse. It contains massive mountains and some of the lowest points on Earth. In Turkey, the Anatolian Plateau is located between the Pontus and Taurus mountains. Mount Ararat is a very high peak in this country. The Zagros Mountains sit in Iran near the border with Iraq. In Yemen, the land rises into high elevations. The region also features the Rub' al Khali, which is one of the largest sand deserts in the world. One of the most famous landmarks is the Dead Sea. It sits on the border of the West Bank, Israel, and Jordan. It is the lowest point on the surface of the Earth.

Geology plays a major role in how the land looks and moves. Three major tectonic plates meet in West Asia. These are the African, Eurasian, and Arabian plates. The boundaries where these plates meet create the Azores-Gibraltar Ridge. This ridge extends through North Africa and the Red Sea into Iran. The Arabian Plate moves northward into the Anatolian plate at the East Anatolian Fault. This movement makes the region seismically active, which means there is often earthquake activity. In the Red Sea, a fault zone creates a trough-like shape. This process is called continental rifting.

The climate is mostly arid or semi-arid. This means the land is often dry and receives little rain. Because of this, water is a very precious resource. Many parts of West Asia face water shortages. People rely on major rivers like the Tigris and Euphrates for irrigation. Irrigation is a way to supply water to crops. In Saudi Arabia, people use large aquifers for water. An aquifer is a layer of rock or soil that holds water underground. These aquifers are found beneath the mountains and in central areas.

Weather patterns in the region include unique wind phenomena. One is the sharqi, which is a seasonal wind from the south or southeast. It blows from April to June and again from September to November. These winds are dry and dusty. They can create sandstorms that are thousands of meters high. These storms can even close down airports. Another wind is the shamal. This is a summer northwesterly wind. It blows over Iraq and the Persian Gulf states. It is often strong during the day but becomes weaker at night.

West Asia is home to about 313 million people. It contains 20 UN member countries that are partly or fully in the region. Of these, 13 are part of the Arab world. Some of the most populous countries are Iran, Turkey, Iraq, Yemen, and Saudi Arabia. The region is also a center for various sports organizations. These include the West Asian Football Federation and the West Asian Tennis Federation. Athletes from 13 specific countries compete in the West Asian Games. This shows how the region is connected through both geography and human activity.
