← GeographyWhich mechanism creates increased salinity near desert stream outflows?
A)Erosion transports distant marine salts
B)Preferential evaporation of stream water✓
C)Increased chemical weathering rates
D)Upwelling of deep saline groundwater
💡 Explanation
When stream water flows from a freshwater source into an arid desert environment, high insolation causes significant evaporation of that water because energy transfer increases and humidity is very low, concentrating dissolved salts. Therefore, higher salinity results, rather than marine transport, accelerated weathering, or groundwater upwelling which are not driven locally.
