← GeographyWhich outcome regarding water chemistry occurs, driven via the ventilation in subterranean caves exhibiting high CO2 concentrations?
A)Enhanced speleothem growth rates occur.
B)Diminished carbonate dissolution near entrances.✓
C)Increased bat guano decomposition rates.
D)Amplified iron oxide deposition ensues.
💡 Explanation
Diminished carbonate dissolution near entrances arises because ventilation causes carbon dioxide to exit the water, less carbonic acid exists, therefore carbonate precipitation occurs closer to the cave entrance, rather than dissolution which happens farther within.
