Africa is the world's second-largest and second most populous continent, after Asia. At about 30,370,000 km² (11,730,000 sq mi) including its adjacent islands, it covers 5.9% of the Earth's total surface area, and 20.3% of the total land area. With over 840,000,000 people (as of 2005) in 57 territories, it accounts for more than 12% of the world's human population.

Etymology

World map showing Africa (geographically)

The name Africa came into Western use through the Romans, who used the name Africa terra — "land of the Afri" (plural, or "Afer" singular) — for the northern part of the continent, as the province of Africa with its capital Carthage, corresponding to modern-day Tunisia.

The Afri were a tribe — possibly Berber — who dwelt in North Africa in the Carthage area. The origin of Afer may be connected with Phoenician `afar, dust (also found in most other Semitic languages); some other etymologies that have been postulated for the ancient name 'Africa' that are much more debatable include:

• the Latin word aprica, meaning "sunny";

• the Greek word aphrike, meaning "without cold" (see also List of traditional Greek place names). The historian Leo Africanus (1495-1554) attributed the origin to the Greek word phrike (φρικε, meaning "cold and horror"), combined with the negating prefix a-, so meaning a land free of cold and horror. However, the change of sound from ph to f in Greek is datable to about the first century, so this is unlikely to be the origin.

Egypt was considered part of Asia by the ancients, and first assigned to Africa by the geographer Ptolemy (85 - 165 AD), who accepted Alexandria as Prime Meridian and made the isthmus of Suez and the Red Sea the boundary between Asia and Africa. As Europeans came to understand the real extent of the continent, the idea of Africa expanded with their knowledge.

Africa is the largest of the three great southward projections from the main mass of the Earth's surface. It includes within its remarkably regular outline an area, of c. 30,360,288 km² (11,722,173 mi²), including the islands.

Separated from Europe by the Mediterranean Sea, it is joined to Asia at its northeast extremity by the Isthmus of Suez (transected by the Suez Canal), 130 km (80 miles) wide. (Geopolitically, Egypt's Sinai Peninsula east of the Suez Canal is often considered part of Africa, as well.) From the most northerly point, Cape Blanc (Ra’s al Abyad) in Tunisia (37°21′ N), to the most southerly point, Cape Agulhas in South Africa (34°51′15″ S), is a distance approximately of 8,000 km (5,000 miles); from Cape Verde, 17°33′22″ W, the westernmost point, to Ras Hafun in Somalia, 51°27′52″ E, the most easterly projection, is a distance (also approximately) of 7,400 km (4,600 miles).
