Which mechanism drives the thermohaline circulation of ocean water when surface water cools significantly in polar regions?

💡 Explanation

When surface water cools, especially in polar regions, density increases due to higher salinity because ice formation extracts freshwater. Increased density initiates convective sinking, driving thermohaline circulation because of density differences. Therefore salinity driven density changes impact thermohaline circulation, rather than wind, Coriolis effect or tidal forces directly impacting convection.
