Question

Why is salt making restricted to the coastal areas

Answer 1

Runoff from the land and openings in the seafloor are two sources of salt in the ocean. The majority of salts dissolved in saltwater come from rocks on land. Because rainwater on land is somewhat acidic, it erodes rocks. The metals are carried away by the hot water when it is discharged from vents in the seabed. The salt is obtained near the coast from the ocean in a very high amount that is why the salt making is restricted to coastal areas.
