← GeographyWhich process causes a ventifact's abrasion rate to increase on salt flats?
A)Salt crystal saltation increases impact energy.✓
B)Frost wedging weakens the rock matrix.
C)Differential weathering destabilizes surface grains.
D)Dissolution creates micro pore instabilities.
💡 Explanation
Ventifact abrasion rates increase when saltating salt crystals collide with rock surfaces because salt crystal saltation’s increased density increases impact energy via kinetic energy transfer. The crystals impact the rock, rather than wind alone, therefore facilitating more rapid weathering than other erosional processes.
