Europe (yŏrˈəp) , 6th largest continent, c.4,000,000 sq mi (10,360,000 sq km) including adjacent islands (1992 est. pop. 512,000,000). It is actually a vast peninsula of the great Eurasian land mass. By convention, it is separated from Asia by the Urals and the Ural River in the east; by the Caspian Sea and the Caucasus in the southeast; and by the Black Sea, the Bosporus, the Sea of Marmara, and the Dardanelles in the south. The Mediterranean Sea and the Strait of Gibraltar separate it from Africa. Europe is washed in the north by the Arctic Ocean, and in the west by the Atlantic Ocean, with which the North Sea and the Baltic Sea are connected.
