Which one of the following mountains lies in between Caspian Sea and Black Sea?
- (a)Caucasus
- (b)Carpathians
- (c)Apennine
- (d)Elburz
Correct — A, Caucasus. The Caucasus Mountains run roughly west-to-east across the isthmus that separates the Black Sea from the Caspian Sea, and are often taken as part of the boundary between Europe and Asia. Their highest peak, Mount Elbrus (about 5,642 m), is the highest mountain in Europe.
- (b)Carpathians — The Carpathians form a great arc across Central and Eastern Europe (Slovakia, Poland, Ukraine, Romania), well to the north-west of the Black Sea, not between the two seas.
- (c)Apennine — The Apennines are the mountain spine running the length of the Italian peninsula in Southern Europe — nowhere near the Caspian or Black Sea.
- (d)Elburz — The Elburz (Alborz) range lies along the southern shore of the Caspian Sea in northern Iran; it borders only the Caspian and does not stretch across to the Black Sea. This is the tempting near-miss.
The Caucasus is a young fold-mountain belt lying on the land bridge between the Black Sea and the Caspian Sea. It is divided into the Greater Caucasus and Lesser Caucasus and hosts Mount Elbrus. The region is culturally significant as a traditional dividing line between Europe and Asia.
Two options sit near the Caspian, so precise placement matters: the Caucasus spans the gap between both seas, whereas the Elburz hugs only the Caspian's southern edge. The Carpathians and Apennines are European ranges far from either sea.
- The Caucasus lies between the Black Sea (west) and the Caspian Sea (east).
- Mount Elbrus (about 5,642 m) in the Caucasus is Europe's highest peak.
- The Caucasus is often treated as part of the Europe-Asia boundary.
- The Elburz (Alborz) is a separate range along the southern Caspian shore in Iran.

- Confusing the Caucasus with the Elburz because both are near the Caspian.
- Placing European ranges (Carpathians, Apennines) into a West-Asian setting.

Same skill — locating and classifying world mountain ranges. UPSC 2024 tests region-and-type matching; this NDA item asks which range sits between the Caspian and Black Seas (the Caucasus).
