← GeographyWhich outcome occurs when the evaporation rate exceeds calcium bicarbonate replenishment in cave stalactite formation?
A)Stalactite growth exceeds dripping dynamics
B)Stalactite growth rate decelerates disproportionately✓
C)Increased manganese deposition darkens formations
D)Fossilized pollen deposits grow rapidly
💡 Explanation
Slower stalactite growth occurs because exceeding calcium bicarbonate replenishment limits the availability of calcium carbonate for deposition in the water, a process called chemical precipitation; therefore, stalactite growth decelerates rather than accelerate. Formation materials alter with external conditions.
