← GeographyWhich outcome occurs more rapidly when granitic rock experiences increased jointing?
A)Elevated chemical weathering process rate✓
B)Reduced mineral ion concentration
C)Increased mechanical strength overall
D)Denser crystalline microstructure formation
💡 Explanation
Increased jointing makes more surface area available for dissolution, a form of chemical weathering; this is because reaction rates depend on contact area; therefore, weathering increases, rather than strength increases without chemical activity.
