Which outcome results when eolian transport encounters topographic obstruction?

💡 Explanation

Barchan dune fields develop because aerodynamic separation in turbulent winds induce sediment deposition via saltation on the leeward side, therefore crests form because particles deposit preferentially on wind-sheltered sites rather than forming ventifacts by concentrated abrasion.
