GEOLOGY

Detailed explanation-1: -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: -Salt in seawater makes it denser than freshwater.

Detailed explanation-3: -Salt water is more dense than fresh water Salt water has more stuff in it than fresh water. That stuff would be the salt, which makes the mass of water greater, without adding much to its volume. Density = mass/volume. Increasing the mass by adding salt increases the density.

Detailed explanation-4: -If you do the same with a cubic foot of water from one of the Great Lakes of North America only about 0.01 pounds of salt or about one-sixth of an ounce of salt would be left behind. Therefore, the sea is about 220 times saltier than our primary freshwater resources.

Detailed explanation-5: -Salinity Affects Density When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases.
