← GeographyWhich morphological change occurs when acidic groundwater's flow rate drops critically inside a karst cave system?
A)Rapid stalactite formation acceleration✓
B)Preferential lateral cave widening
C)Dissolution rate equilibrium decline
D)Deeper channel incision intensifies
💡 Explanation
Flow reduction restricts the supply of dissolved calcium bicarbonate maintaining disequilibrium conditions for precipitation; thus, stalactite formation accelerates rather than dissolution decelerating, because reduced flow creates supersaturation locally, promoting faster mineral deposition instead of continued dissolution.
