Which process decreases when glacial freshwater reduces salinity?

💡 Explanation

Thermohaline circulation weakens because it is driven by density gradients; decreasing salinity reduces water density and therefore diminishes the pressure differences which drive deep water formation, rather than increasing upwelling or kinetic energy.
