Which property change occurs because desert ventifacts experience enhanced mineral weathering?

A)Increased surface dissolution rate
B)Decreased frictional coefficient
C)Reduced thermal expansion rate
D)Elevated aerodynamic drag coefficient

💡 Explanation

Windblown sand causes surface abrasion, enhancing microfractures; this 'sandblasting' increases surface area, accelerating chemical interactions; this leads to increased dissolution rates, therefore causing greater weathering; rather than changing the coefficient.
