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.

• Which effect accelerates oxbow lake formation as a fluvial meander migrates laterally?
• Which process limits explosive volcanic eruption column height during strong plinian events?
• Which landform evolution occurs when sustained abrasion by sand creates ventifacts?
• Which outcome occurs when atmospheric CO2 decreases globally?
• Which outcome occurs when differential slip exceeds friction limits on strike-slip faults traversing sedimentary strata?
• Which outcome occurs when sediment supply exceeds stream transport capacity near a mountain front, promoting widespread aggradation?
