    Explain the use of salt water lakes in India with particular reference to Chilka and Sambhar lakes.                                              (5)  

    Answer:

    Sambhar lake is India's largest saline lake and has made Rajasthan the third largest salt producing state in India. It produces about 2 lakh tonnes of clean salt every year. Salt is produced by evaporation of brine. This lake is also recognized as a wetland of international importance because it is a key wintering area for flamingos and other birds that migrate from northern Asia. Chilka lake in Odisha is the largest brackish water lake in India. It is the wintering ground for migratory birds on the Indian sub-continent. The lake is home to a number of threatened species of plants and animals. It is an ecosystem with large fishery resources sustaining 150,000 fishermen living nearby.
