    From where salt comes?

    Answer:

    Sea water contains many salts mixed in it. One of these salts is the common salt. When sea water is allowed to stand in shallow pits, water gets heated by sunlight and slowly turns into water vapour through evaporation. The water evaporates completely leaving behind the solid salt. Common salt is then obtained from this mixture of salts by further purification.
