Answers. Best Answer: Evaporation will increase salinity, the water will evaporate but the salt will remain so the concentration goes up. Ocean water will become less saline near rivers which are adding fresh water to the ocean. Melting glaciers and rainfall will add fresh water also and decrease the salinity.
Of these sodium chloride accounts for 77.8%. The presence of salts in ocean water causes salinity, which is known as the salinity of ocean water. Salinity is expressed by the amount of salts dissolved. The technical term for saltiness in the ocean is salinity. In oceanography, it has been traditional to express salinity not as percent, but as parts per thousand (â°), which is approximately grams of salt per kilogram of solution.
