In which of the following rivers, the upper course contains fresh water but saline water flowing at the lower part?
Verified Answer
A. Barak river
B. Luni river
C. Ghaggar river
D. None of the above
Explanation:
The Luni River is the only major river in the Thar Desert of Rajasthan. It originates in the Aravalli Range and flows towards the Rann of Kutch. Its upper course has fresh water, but as it flows through the desert, its water becomes saline due to high evaporation and the presence of salt-rich soils, especially in its lower reaches.
