Answer:
Seawater is trapped in large, shallow pools and allowed to stand there. The sun’s heat evaporates the water slowly, and common salt is left behind. This salt is further collected, purified and packed for domestic use. The concentrated brine precipitates the salt, which is then gathered by mechanical harvesting machines. Any impurities that may be present in the brine are drained off and discarded before harvesting.
It is used as a seasoning in foods, cooking, cosmetics and for preserving food.
Sea salt and table salt contain comparable amounts of sodium by weight
