← GeographyWhich outcome occurs when persistent katabatic winds impact rock surfaces in an Antarctic polar desert?
A)Formation of ventifacts with polished surfaces✓
B)Deposition of thick loess soil layers
C)Development of playa salt flats
D)Intensified chemical weathering via hydrolysis
💡 Explanation
The formation of ventifacts occurs because katabatic winds, laden with ice crystals, promote abrasion; therefore, rocks are sculpted and polished by aeolian erosion, rather than accumulating fine sediment, such as loess, or being altered chemically.
