Which phenomenon drives deep ocean thermohaline circulation due to density differences?

💡 Explanation

When seawater becomes denser due to cooling/freezing or increased salinity, convective sinking occurs, because denser water sinks while less dense water rises, driving thermohaline circulation. Therefore, differential solar heating and salinity create density differences, rather than atmospheric pressure, tidal forces, or geothermal vents which have localized impacts.
