Which mechanism causes meromictic lakes to exhibit permanently stratified layers?

💡 Explanation

When a meromictic lake possesses a significant difference in salinity between its upper and lower layers, checmocline and, thus, limited mixing occurs because the denser, saltier water remains at the bottom, preventing convection. Therefore differential salinity results in stable stratification, rather than the Coriolis effect, geothermal heating, or algal blooms which contribute minor or regional influence.
