The salt lakes of Rajasthan originated through:

Correct option is B

Correct Answer: (b) Wind activity
Explanation:
→ Many saline lakes in Rajasthan (e.g., Sambhar, Didwana) are playa or deflation basins formed by wind erosion and evaporation in arid landscapes.
→ Wind action removes finer sediments and promotes concentration of salts as water evaporates.
Information Booster:
→ These lakes are seasonal/shallow and their salinity increases during dry periods due to high evaporation and low inflow.
Additional Information (Other Options):
(a) Volcanic activity: forms crater lakes, not typical for Rajasthan.
(c) Tectonic activity: forms rift/tectonic lakes (different origin).
(d) Glacial activity: forms glacial lakes—absent in Rajasthan’s climate.
