Answer:
Evaporation process
Explanation:
The evaporation process is responsible for the increase in the concentration of salt in the oceans or seawater.
Within the ocean there are certain places where there occurs little or no rainfall. The temperature in this region is relatively high and dry, due to which there occurs the process of evaporation. Because of the absence of rainfall, the rate of evaporation is higher in this region compared to the rate of precipitation. So when this process takes place, it eliminates the water quantity present in it, resulting in the formation of salts.
The salinity of the ocean increases because of the high rate of evaporation of the ocean water as well as forming of the sea ice.
