← GeographyWhich feedback results when increased rainfall accelerates limestone bedrock weathering?
A)Karstification accelerates bedrock structural failure✓
B)Halocline formation decreases freshwater storage
C)Isostatic rebound decreases crustal elevation
D)Oxidation buffers increased stream acidity
💡 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.
