← GeographyWhich outcome occurs when ephemeral desert stream discharge ceases during peak evaporation?
A)Playa lake chloride mineral accumulation✓
B)Increased longshore bar sediment erosion
C)Enhanced fluvial terrace aggradation cycles
D)Accelerated braided channel avulsion rate
💡 Explanation
Halite and gypsum (salts) accumulate because evaporative pumping concentrates dissolved salts in a playa, leading to mineral deposition rather than sediment erosion elsewhere. Playa chloride mineral accumulation is favored therefore, rather than coastal, stream, or channel processes.
