what physical feature forms the eastern boundary of europe
Geography of Europe Europe is traditionally defined as one of seven continents. 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 Kura River 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.
Germany Germany is in Western and Central Europe, with Denmark bordering to the north, Poland and the Czech Republic to the east, Austria to the southeast, Switzerland to the south-southwest, France, Luxembourg and Belgium lie to the west, and the Netherlands to the northwest. It lies mostly between latitudes 47° and 55° N and longitudes 5° and 16° E. Germany is also bordered by the North Sea and, at the north-northeast, by the Baltic Sea. With Switzerland and Austria, Germany also shares a border on the fresh-water Lake Constance, the third largest lake in Central Europe.[94] German territory covers 357,021 km2 (137,847 sq mi), consisting of 349,223 km2 (134,836 sq mi) of land and 7,798 km2 (3,011 sq mi) of water. It is the seventh largest country by area in Europe and the 62nd largest in the world.[95]
