nd minerals from all of the rivers that flow into it. In other words, the ocean today probably has a balanced salt input and output (and so the ocean is no longer getting saltier).
Why is the ocean water salty Upsc?
Factors Affecting Ocean Salinity The salinity of water in the surface layer of oceans depend mainly on evaporation and precipitation. Surface salinity is greatly influenced in coastal regions by the fresh water flow from rivers, and in polar regions by the processes of freezing and thawing of ice.
Where does salt we eat come from?
Sources. Salt comes from two main sources: sea water and the sodium chloride mineral halite (also known as rock salt). Rock salt occurs in vast beds of sedimentary evaporite minerals that result from the drying up of enclosed lakes, playas, and seas.
