Europe is bounded to the north by the Arctic Ocean, to the west by the Atlantic Ocean, to the south by the Mediterranean Sea, and–according to the traditional geographic definition–to the southeast by the waterways adjoining the Mediterranean to and including the Black Sea, and the Caucasus Mountains (in Caucasia). Europe's eastern frontier is vague, but has traditionally been given as the divide of the Ural Mountains and the Caspian Sea to the southeast. The Urals are considered by most to be a geographical and tectonic landmark separating Asia from Europe."
