← GeographyWhich outcome results when a cave system's water table rises above speleothem formations?
A)Accelerated stalactite dissolution begins
B)Ferromanganese crust precipitation occurs✓
C)Increased cave roof collapse events
D)Enhanced aragonite needle formation occurs
💡 Explanation
Ferromanganese crust precipitation increases because the increased water saturation introduces dissolved iron and manganese, which causes oxidation and deposition via chemical precipitation rather than dissolution; therefore, crust forms, rather than stalactites dissolving.
