Which mechanism sustains deep ocean thermohaline circulation after surface water increases in density?

💡 Explanation

When surface water density increases (due to cooling or increased salinity), convection currents begin because denser water sinks, displacing less dense water below and perpetuating the cycle. Therefore convection drives the water flow, unlike wind driven advection diffusion which require different force mechanisms.
