Which district of Rajasthan receives the lowest average annual rainfall?
- A.Churu
- B.Jaisalmer
- C.Bikaner
- D.Nagaur
Correct answer
Explanation
The correct answer is B, Jaisalmer. It lies in the extreme west of the state, farthest from both branches of the south-west monsoon, and parts of the district record under 200 millimetres a year, which is why the sand dunes there are the largest and the most mobile in Rajasthan. Option A, Churu, is one of the hottest places in the country in summer and one of the coldest in winter, but it is further east and gets more rain than Jaisalmer. Option C, Bikaner, and Option D, Nagaur, also lie in the arid and semi-arid belt and receive more. Pair the extremes for the exam: the least rain in Jaisalmer and the most at Mount Abu in Sirohi, with the Aravalli range dividing the two.
