← GeographyWhich process creates thermohaline circulation within deep glacial lakes?
A)Convection driven by density differences✓
B)Advection caused by wind forcing
C)Diffusion driven by solute gradients
D)Conduction driven by geothermal heating
💡 Explanation
When surface water cools and becomes saltier (denser), convection occurs and denser water sinks, displacing less dense water because density differences are the primary driver. Therefore, convection driven by density differences creates thermohaline circulation, rather than advection, diffusion, or conduction which are less dominant in these systems.
