<h3><u>Answer;</u></h3>
Temperature and salinity
<h3><u>Explanation;</u></h3>
- Differences in the density of water can 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.
- The different densities cause the water to move, forming a density current. In the oceans, the deep,bottom currents are colder and saltier than the surface currents.
