Which is India’s largest inland saline lake?
Last Updated:
This question examines an important river-or-lake fact: “Which lake in India is a remnant of an ancient sea?” The correct answer is Sambhar Lake. Sambhar Lake in Rajasthan is believed to be a remnant of an ancient sea - specifically the Tethys Sea (which covered much of the Indian subcontinent millions of years ago). The saline nature of the lake supports this theory. The salt deposits in Sambhar are remnants of ancient marine evaporites. They may contain fresh, brackish or saline water, so terms such as lake, lagoon, reservoir and wetland should not be used interchangeably. Examination questions often confuse a river’s source with its mouth, a left-bank tributary with a right-bank tributary, or a natural lake with a reservoir.
