Which mountain range is commonly described as the traditional boundary between Europe and Asia?

• A. Alps
• B. Ural Mountains
• C. Carpathians
• D. Caucasus Mountains

Answer: (B)

The main idea here is the line geographers traditionally use to separate Europe from Asia. The Ural Mountains run roughly north–south across Russia, stretching from the Arctic down toward the Ural River. They form a natural break between the western European landmass and the vast areas of Siberia to the east, so they’re taken as the classic boundary between the two continents in many definitions. The other ranges are notable in Europe but don’t serve as the conventional continental divider: the Alps are in western Europe, the Carpathians arc through Central and Eastern Europe, and the Caucasus sit at the southern edge of the region and are sometimes considered a boundary in some views, but the long-standing traditional boundary is the Ural Mountains.
