Which outcome occurs when persistent katabatic winds impact rock surfaces in an Antarctic polar desert?

💡 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.
