Which condition increases the rate of speleothem formation?

💡 Explanation

Increased CO2 concentration enhances carbonic acid formation, increasing limestone dissolution via chemical weathering; this solution transports increased calcium carbonate, which precipitates as speleothems. Stalactite growth accelerates because of this higher concentration rather than pressure, humidity, or drip rate variability effects.
