Which of the following international rivers flows through more countries than any other river in the world, emptying into the Black Sea?

💡 Solution & Explanation

The Danube River originates in Germany's Black Forest and flows eastward through or along the borders of ten countries before emptying into the Black Sea, passing through more nations than any other river globally. The Amazon and Nile are longer by volume or length, but they cross fewer sovereign international borders. Major river basins and international boundaries form a core part of physical geography syllabi.
