Which feedback results when increased rainfall accelerates limestone bedrock weathering?

💡 Explanation

Increased rainfall causes accelerated dissolution of limestone bedrock because increased percolation widens fractures and strengthens chemical weathering; therefore increased karstification promotes sinkhole formation and weakens the structural integrity, rather than promoting other geological formations.
