Question

How do changes in temperature and salinity affect ocean currents??????

Answer 1

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).

Answer 2

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
