How is desert pavement formed?
Answer and explanation
Correct answer: Coarse pebbles remain after wind removes fine particles
Desert pavement is a tightly packed surface layer of pebbles and coarse stones in an arid area. Persistent wind deflation removes loose dust, sand, and other fine particles, while heavier gravel is difficult to transport and remains behind. Over time, the residual stones protect the surface and create a stony pavement. Therefore option D is correct; the other choices involve glacial, tidal, or river-mouth deposition.
