← GeographyWhich feedback arises when increased rainfall rapidly saturates soluble bedrock, forming new sinkholes?
A)Increased surface water, greater erosion✓
B)Shallower groundwater tables, less residence
C)Decreased runoff, more sediment trapping
D)Reduced infiltration, greater soil stability
💡 Explanation
Water saturation creates positive feedback, as water infiltration widens fractures via dissolution, thus accelerating more sinkhole formation because this increases surface water flow and causes greater erosion rather than stabilising soil.
