Europe, the smallest of the five continents. Europe is a great peninsula running west from Asia. Europe is bordered on the north by the Barents Sea, west by the Atlantic Ocean. The eastern land boundary is traditionally defined by a line following the Ural Mountians, southeast to the Caspian Sea, then across to the Black Sea through the Caucacasus Mountains, and cutting through the Bosporus, Sea of Marmara, and the Dardanelles. On the south the continent is bounded by the Caucasus region and the Black Sea, Sea of Marmara, and Mediterranean Sea.
