Multiple Choice

-Which of the following is the best explanation for the relationship between salinity and depth in the mixed layer?

• A)Salt is only slightly soluble in cold water,so salinity always decreases with water temperature.
• B)Warm water is evaporating at the surface,so the water becomes saltier at the surface.
• C)The increase in density and pressure with depth causes salt to precipitate out of the water,so the water becomes less salty with depth in the mixed layer.
• D)Salt water is less dense than fresh water,so water with the highest salt content would rise to the surface.
