because it is less dense than the sea water
Salt layers form at the bottom of the sea because as seawater evaporates, the salt content becomes more concentrated. Eventually, the concentration reaches a point where the salt precipitates out and settles on the seabed, forming solid salt layers over time.
Sodium chloride is extracted from mines or sea waters.
salt is formed in the sea by water from rivers and streams washing salt from the ground into the ocean.

Salt used in cooking is derived from seawater (sea salt) or from layers of salt in mineral deposits (rock salt or mineral salt).

The salt formed by the natural evaporation of sea water is known as sea salt. It typically retains trace minerals and elements from the ocean, giving it a slightly different flavor profile compared to table salt. Sea salt is often used in cooking and as a finishing salt.
High tides flood the salt pans with sea water which evaporates to leave behind salt deposits. This is how salt deposits are formed.
After the evaporation of water crystals are formed.
