Physiographically, it is the northwestern peninsula of the larger landmass known as Eurasia (or the larger Afro - Eurasia); Asia occupies the eastern bulk of this continuous landmass and all share a common continental shelf . Europe's eastern frontier is delineated by the Ural Mountains in Russia . The southeast boundary with Asia is not universally defined, but the modern definition is generally the Ural River or, less commonly, the Emba River . The boundary continues to the Caspian Sea, the crest of the Caucasus Mountains (or, less commonly, the river Kura in the Caucasus), and on to the Black Sea . The Bosporus, the Sea of Marmara, and the Dardanelles conclude the Asian boundary . The Mediterranean Sea to the south separates Europe from Africa . The western boundary is the Atlantic Ocean . Iceland, though on the Mid-Atlantic Ridge and nearer to Greenland (North America) than mainland Europe, is generally included in Europe for cultural reasons and because it is over twice as close to mainland Europe than to mainland North America . There is ongoing debate on where the geographical centre of Europe falls . </P> <P> Some geographical texts refer to a Eurasian continent given that Europe is not surrounded by sea and its southeastern border has always been variously defined for centuries . </P>
