← GeographyWhich consequence results when increased acidic rainfall overwhelms limestone's buffering capacity?
A)Accelerated sinkhole formation within karst landscapes✓
B)Increased rates of glacial ice accumulation
C)Decreased rates of soil nutrient leaching
D)Reduced frequency of coastal flooding events
💡 Explanation
Accelerated sinkhole formation occurs, driven by increased limestone dissolution; because the acidic rainfall enhances bedrock weathering via CHEMICAL WEATHERING, weakening the rock structure, therefore sinkholes develop more quickly, rather than other landform modifications under vastly different processes.
