Which feedback results when increased rainfall saturates soluble carbonate bedrock?

💡 Explanation

Increased rainfall in carbonate regions leads to accelerated sinkhole development through dissolution. Saturation of the bedrock heightens chemical weathering rates via **positive feedback**, because newly formed pathways enhance fluid flow rather than inhibiting weathering. Therefore sinkholes appear rapidly.
