Which mechanism contributes to the higher dissolved mineral concentration in endorheic lake systems compared to exorheic systems?

💡 Explanation

Endorheic lakes lack outflow, leading to evaporative concentration, because water evaporates while dissolved minerals remain, increasing their concentration over time. Therefore, evaporative concentration is the key mechanism, rather than reverse osmosis, increased infiltration, or decreased weathering which have minimal effect on overall salinity.
