Which outcome is most likely when glacial meltwater inflows into a pluvial lake?

💡 Explanation

Decreased salinity occurs because the addition of relatively pure glacial meltwater dilutes the existing dissolved salts via hydraulic mixing. Therefore, the overall lake salinity decreases, rather than increased groundwater recharge or stratification.
