On exposed playa surfaces, which effect primarily increases when fine sediment cohesion weakens?

A)Accelerated deflation rates
B)Increased chemical weathering levels
C)Expanded alluvial fan deposits
D)Reduced saltation threshold velocity

💡 Explanation

Increased fine sediment availability promotes accelerated deflation rates, because weakened cohesion allows wind to entrain more particles. This causes increased winnowing of material from the surface, therefore boosting overall deflation, rather than other geomorphic processes or threshold reductions.
