← GeographyWhich environmental outcome negatively impacts stalactite formation due to increased acidity?
A)Enhanced chemical weathering of limestone✓
B)Accelerated deposition of calcium carbonate
C)Reduced infiltration of surface water
D)Increased evaporation within cave systems
💡 Explanation
Enhanced chemical weathering decreases stalactite growth. Acidic rainwater dissolves limestone via carbonation because H+ ions react with CaCO3, forming soluble calcium bicarbonate; therefore, limestone erodes, rather than precipitates new structures.
