Question

How does the salinity of ocean water affect the ocean currents?

Answer 1

The salinity of ocean water affects ocean currents by influencing water density. Higher salinity makes water denser, causing it to sink below lower salinity, lighter water. This density difference drives vertical and horizontal water movement, contributing to the flow and layering of ocean currents. For example, denser, high-salinity water from enclosed seas flows beneath lighter, low-salinity open ocean water, affecting current direction and structure.
