Answer to Question 1

Desert slopes are largely unprotected by vegetation, and thin soils limit infiltration rates. While annual rainfall in deserts is low, individual rain events can produce large amounts of runoff that gets rapidly funneled into washes.

Answer to Question 2

Active dunes travel, or migrate, when wind-eroded sand from their upwind (windward) slope moves by saltation and surface creep over the dune crest and onto the steep leeward (downwind) slope, which is the slip face.
