← GeographyWhich deposition pattern arises when prevailing winds encounter topographical barrier?
A)Loess deposition windward of barrier✓
B)Eolian ripples parallel to airflow
C)Barchan dunes migrating upwind
D)Deflation hollows on leeward slopes
💡 Explanation
Loess deposition occurs when wind velocity decreases crossing a barrier; airflow separation creates settling because particles lose kinetic energy via gravitational sorting, forming extensive mantles windward rather than leeward depositional features driven by constant saltation.
