← GeographyWhich abrasive outcome is amplified when ventifact formation occurs in a sodium-rich lacustrine environment?
A)Increased undercutting of yardang bases✓
B)Reduced aeolian saltation threshold
C)Enhanced chemical weathering of clasts
D)Decreased surface creep rates
💡 Explanation
Increased sodium deposition causes accelerated case hardening because salt accumulation increases the rock's susceptibility to wind abrasion, therefore enhancing the undercutting of yardangs, rather than directly influencing aeolian transport thresholds or general weathering.
