So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water.
Changes in the density set these currents in motion. Some ocean currents are set in motion by the wind. Other ocean currents are created by something. you canât see or feel. Differences in the density of water can also cause currents to form and move. 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). For. example, at the same temperature (20 o C) the density of salt water is 1.025 g/ml and fresh water. 0.998 g/ml.
