Which mechanism forms widening cave passages near the water table?

💡 Explanation

Preferential dissolution causes cave passages to widen because the water table’s fluctuating levels allow for increased carbonate dissolution at specific levels; therefore horizontal conduits expand especially around the water table rather than random cave expansion.
