Which outcome occurs when increased aridity affects playa lakebeds?

💡 Explanation

As playa lakebeds dry out due to increased aridity, exposure to wind causes deflation, removing fine sediments and leaving behind larger pebbles. This desert pavement forms because deflation strips away smaller particles, therefore an armored surface develops rather than chemical alteration.
