second-largest continent, and the continent with the most
countries, Africa is the largest of the three great southward
projections from the main mass of the earth’s surface.
Separated from Europe by the Mediterranean Sea, it is joined
to Asia at its northeast extremity by the Isthmus of Suez.
For geopolitical purposes, the Egyptian Sinai Peninsula is
often included as part of Africa. The Romans gave the continent
its name following the conquest of Carthage in 146 BC, probably
naming it after the Afri tribe.
