← GeographyWhich process regulates salinity in closed-basin lakes under high evaporation rates when inflow halts?
A)Density stratification prevents mixing
B)Mineral precipitation forms evaporites✓
C)Thermal expansion lowers water level
D)Osmotic pressure reverses water flow
💡 Explanation
When inflow halts and evaporation is high, salinity rises beyond saturation points for dissolved minerals which leads to mineral precipitation creating evaporite deposits because of solubility limits. Therefore mineral precipitation regulates salinity rather than stratification, expansion, or reversed osmotic flow which require different hydrological driving forces.
