Explain how tempe

Salinity Affects Density. When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases. The more salt there is dissolved in the water, the greater its salinity. Temp causes water to rise or sink through convection, and salinity affects the density of the water, so higher salinity water will contribute to deep water currents Density is affected by temperature and salinity. Cold water or water with dissolved salts (higher salinity) is denser than warm water or water without dissolved salts (low or no salinity).
