← GeographyWhich geological outcome is amplified when increased rainfall accelerates basalt weathering?
A)Enhanced CO2 atmospheric sequestration✓
B)Accelerated formation of diamond deposits
C)Increased metamorphic rock formation rates
D)Reduced rates of glacial retreat locally
💡 Explanation
Enhanced rainfall reacting with newly exposed basalt increases the rate of chemical weathering via carbonation because basalt readily reacts with atmospheric CO2; therefore, weathering enhances CO2 drawdown, rather than impeding diamond formation or rock metamorphism in most geological zones.
