← GeographyWhich abrasive geological consequence is accelerated when surface winds exceed threshold values interacting with exposed rock features?
A)Extensive ventifact formation on desert pavements✓
B)Increased chemical weathering of silicate rocks
C)Enhanced deposition of loess sediments
D)Maximum surface creep of coarse grains
💡 Explanation
Increased wind speeds intensify aeolian particle abrasion by saltation, accelerating ventifact creation; this is because sand grains collide with rock surfaces with greater force under stronger wind; therefore ventifact formation increases rather than other weathering processes.
