Which of the following statements is not correct?
- AThe Western Ghats are relatively higher in their northern region.Correct
- BThe Anai Mudi is the highest peak in the Western Ghats.
- CTapi river lies to the south of Satpura.
- DThe Narmada and the Tapi river valleys are said to be old rift valleys.
Explanation
Statement A is incorrect because the altitude of the Western Ghats actually increases from north to south. While the northern section in Maharashtra and Gujarat has a lower average elevation, the southern section contains the highest peaks of the range.
Regarding the other options: Anai Mudi is indeed the highest peak at 2,695 meters, located in the southern part of the range. The Tapi river flows parallel to and south of the Satpura range. Both the Narmada and Tapi flow through ancient rift valleys created by tectonic shifts.
Therefore, since the height of the Western Ghats increases toward the south, the statement claiming they are higher in the north is the incorrect one.
