Asia is the world’s largest and most populous continent. It is located mainly in the eastern and northern hemispheres covering 8.7 percent of the Earth’s whole surface area and making up 30 percent of its land area. With about 4.3 billion people, it hosts 60 percent of the world’s current human population. This continent has a high growth rate in the modern era. For example, during the 20th century, Asia’s population almost quadrupled.

This continent is defined as making up the eastwards 4/5ths of Eurasia. It’s positioned to the east of the Suez Canal, the Ural Mountains and the Ural River, and south of the Caucasus Mountains and the Black and Caspian Seas. It’s bordered on the east by the Pacific Ocean, on the south by the Indian Ocean and on the north by the Arctic Ocean.

The initial distinction between Asia and Europe was created by the ancient Greeks. They utilized the Aegean Sea, the Dardanelles, the Sea of Marmara, the Black Sea, the Kerch Strait, the Bosporus, and the Sea of Azov as the border between the two. The Nile was frequently used as the border between Africa and Asia, although some Greek geographers proposed the Red Sea would create a better boundary. During the 15th century, the Red Sea became the established boundary between Asia and Africa, replacing the Nile. As exploration developed, the border between Asia and Europe needed to be refined, as the borders at the time didn’t extend to the arctic.

This continent was initially a concept of Western civilization. The name “Asia”, in a variety of forms in a large number of modern languages is of unknown eventual provenience. The etymology and language of origin are not certain. It seems to be one of the most ancient of recorded names. Numerous theories have been published.

As the largest continent on Earth, it covers 8.8 percent of the Earth’s overall surface area and has the largest coastline, at 39,022 miles. It contains extremely diverse climates and geographic characteristics. The climates range from sub arctic to arctic in Siberia to tropical in southern India and Southeast Asia. It’s moist across the southeast areas, and dry across the majority of the interior.
