Answer to Question 1

Answer: Scenario A could involve the removal of fine-grained sediments (silt and sand) from the surface by deflation. The concentration of larger, coarse-grained particles increases until the fine-grained sediments are completely removed. Scenario B might involve fine-grained particles sifting and working their way between open pore spaces by wind and rainwater infiltration. Over time, silt continues to accumulate and lifts the coarser particles, creating desert pavement.

Answer to Question 2

D
