Detailed explanation-1: -Salinity describes how much salt is dissolved in a sample of water. The more salt there is dissolved in the water, the greater its salinity. When comparing two samples of water with the same volume, the water sample with higher salinity will have greater mass, and it will therefore be more dense.
Detailed explanation-2: -As the salinity of water increases, the freezing point decreases (29), meaning that an ocean of higher salinity has less potential to form sea ice and therefore remains ice free at much lower temperatures.
Detailed explanation-3: -The Baltic Sea in northern Europe has the lowest salinity of any sea, with an average salt concentration of 7–8 grams per kilogram of water (meaning that the water is 0.7–0.8% salt by weight).
Detailed explanation-4: -The saltiest ocean water is in the Red Sea and in the Persian Gulf region (around 40‰) due to very high evaporation and little fresh water inflow.
