Which landscape alteration advances because sustained desert deflation?

💡 Explanation

Lag gravel pavements form as deflation removes finer particles blown by wind because the aerodynamic sorting elevates coarser rock. Pavements develop rather than chemical alteration, therefore no moisture nor valleys from incision.
