← GeographyWhich mechanism accelerates the collapse of karst terrain?
A)Preferential dissolution widens fracture networks✓
B)Oxidation creates insoluble iron oxides
C)Hydration reduces mineral volume stability
D)Crystallization blocks water infiltration pathways
💡 Explanation
Preferential dissolution causes widening along joints and fractures due to increased surface area in contact with acidic rainwater, which weakens the rockmass therefore creating increased instability, rather than other weathering processes or blockage of drainage.
