Which mechanism causes increased salinity in closed-basin lakes in arid climates experiencing long-term drought?

💡 Explanation

When drought occurs, decreased inflow coupled with high evaporation rates causes evaporative concentration, intensifying the accumulation of dissolved salts, as water molecules vaporize and leave salts behind. Therefore, salinity increases, rather than weathering, aerosol deposition, or groundwater upwelling, all which represent salinity increase from other material inputs.
