Africa : continent of the eastern hemisphere straddling the Equator, separated from Europe by the Strait of Gibraltar, and adjoining Asia at the Sinai Peninsula area 11,677,239 square miles (30,244,049 square kilometers) — Webster
Africa is the world’s second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth’s total surface area and 20.4% of its total land area. With 1.2 billion people as of 2016, it accounts for about 16% of the world’s human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two de facto independent states with limited or no recognition.
Africa hosts a large diversity of ethnicities, cultures and languages. In the late 19th century European countries colonized most of Africa. Africa also varies greatly with regard to environments, economics, historical ties and government systems. However, most present states in Africa originate from a process of decolonization in the 20th century. African nations have attempted to cooperate through the establishment of the African Union, which is headquartered in Addis Ababa. — Wikipedia
