Question

One - tenth of the total salt produced in India comes from _______ .
A.Tamil Nadu Coast
B.Sambhar Lake
C.Chilka Lake
D.Wular lake

Answer 1

Hint: Salt is a very essential part of almost every food item . It is a mineral which is composed mainly of sodium chloride $(NaCl)$ . It is present in vast quantities in seawater and hence is extracted from there .

Complete answer:
-Salt lakes are formed when the water flowing into it from different sources containing salts and minerals cannot exit the lake because it is terminal .When this water evaporates it leaves behind the salts making it a concentrated salt lake for excellent salt production.
-India ranked 3 in the total production of salt as per 2019, the first being China followed by the United States. India produced 19,248 metric tons of salt in 2019.
-One-tenth of the total salt produced in India comes from The Sambhar Lake.
-It is situated in east-central Rajasthan , west of Jaipur .
-Through the evaporation of water brought in it by the annual river flooding , the accumulation of soluble sodium compounds has taken place.
-These compounds are stored in the lake's underlying silt.
-Many halophilic flora and fauna are present in this lake.
-The salt $(NaCl)$ concentration of this lake varies from season to season. Also the colour of the lake changes according to the organisms present ,that is, orange, green, pink ,purple and red. Other than salt production, this lake has been designated a Ramsar site as it has become a key wintering area for thousands of flamingos and other migratory birds.
Hence option B is correct .

Note:
The lake bed which is usually dry in summer months, is covered with salt sheets which resemble snow when viewed by a far off place.
