← GeographyWhich morphological outcome results from seasonally reduced solutional activity in cave systems?
A)Thicker, banded stalactite layering forms✓
B)Increased ceiling collapse near entrances
C)Faster dissolution rate of surrounding bedrock
D)Lower cave air CO2 concentration develops
💡 Explanation
Thicker layering arises because the slowing of drip rates increases the deposition from each event. This is due to evaporative concentration creating supersaturation; therefore, thicker bands form, rather than uniform distribution like constant seeps.
