← GeographyWhich outcome accelerates near limestone bedrock when carbonic acid concentration sharply increases?
A)Increased rates of karst topography formation✓
B)Decreased mineral precipitation rates nearby
C)Elevated regional aggregate soil alkalinity
D)Reduced sediment erosion rates overall
💡 Explanation
Concentrated carbonic acid causes increased rates of limestone dissolution because of enhanced chemical weathering; therefore karst topography forms quicker, rather than slower alkaline soil development occurring because of reduced weathering rates.
