Which process creates thermohaline circulation within deep glacial lakes?

💡 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.

• Which process causes the formation of a volcanic arc when oceanic lithosphere subducts beneath continental lithosphere?
• Which phenomenon increases when topsoil experiences reduced throughflow?
• Where does the formation alluvial fans often occur when a river empties into a lake?
• Which risk escalates as near-surface permafrost thaws in high-latitude coastal regions due to thermokarst processes?
• Which risk increases as floodplain development restricts space allowing for proper river levee maintenance and inspection?
• Which outcome is amplified by the increased frequency of dust storms in playas?
