Saline soil in Rajasthan is most typically found around which of the following?
- A.Pachpadra and Didwana
- B.Kota and Bundi
- C.Alwar and Bharatpur
- D.Banswara and Dungarpur
Correct answer
Explanation
The correct answer is A, Pachpadra and Didwana. These, with the Sambhar basin, are the inland basins of Rajasthan: the streams that reach them have no outlet to the sea, so the water evaporates and leaves its salts behind, and the same salt is worked commercially at Sambhar, Didwana and Pachpadra. Option B, Kota and Bundi, lies in Hadoti where the soil is medium black and the Chambal gives plentiful water. Option C, Alwar and Bharatpur, is on the fertile eastern alluvial plain. Option D, Banswara and Dungarpur, in the humid south, has mixed red and black soil. The logic to carry into the exam is simple: inland drainage with no outlet means salt, so salt lakes and saline soils appear together on the map.
