Question

4.
Explain how salinity changes the movement of ocean currents.

Answer 1

Deep ocean currents

Differences in water density, resulting from the variability of water temperature (thermo) and salinity (haline), also cause ocean currents. ... Dense-cold-salty water sinks to the ocean bottom. Surface water flows in to replace the sinking water, which in turn becomes cold and salty enough to sink.
