Salinity is the percent of salt found inside of fresh water....
the surface of the ocean, like the top. where the water is less dense. less dense, less salinity, more dense, more salinity,think of it that way, that's how i do it.
Salinity of water increase by evaporation.
Lake Assai in Djibouti, Africa is the third saltiest body of water. Its salinity percentage is approximately 34.8 percent. The saltiest body of water is Don Juan Pond in Antarctica at a salinity percentage of 40 percent. The Dead Sea ranks fourth on this list.
Saltwater does not have one definite salinity - for instance the salinity of the water in the Dead Sea is different to that of the Atlantic. Indeed the salinity of the sea itself can vary.
River water has a higher salinity, which means there is a lot of salt in the water. In the sea, however, the salt sinks to the bottom of the ocean, so the sea water has a lower salinity.
The salinity of the Red Sea is high because it has a high rate of evaporation compared to precipitation. Also, there are no freshwater sources draining into the sea.
The amount of salinity that there is in the sunlight zone is about 3.5 percent. About 90 percent of sea life also resides in this zone.
The Red Sea receives little rain fall and has high evaporation rates resulting in high-salinity water. The Baltic Sea contains low-salinity water as a result of abundant freshwater runoff from the surrounding land.
depth and salinity increases density of sea water increases
the density of sea water increases as salinity increases and temperature decreases
i believe it is salinity
