Which mechanism causes increased lake salinity when endorheic basin evaporation rates significantly exceed inflow?

💡 Explanation

When evaporation exceeds inflow in an endorheic basin (closed drainage), ions accumulate because water molecules evaporate, leaving dissolved minerals (salts) behind leading to increasing salinity. Therefore evaporative concentration occurs, rather than cryogenic separation, reverse osmosis, or biogenic uptake, each relying on different processes.
