← GeographyWhich condition causes increased cave system formation via dissolution?
A)Increased soil acidity levels increase dissolution✓
B)Decreased temperature gradients reduce groundwater flow
C)Plant root density reinforces cave structure
D)Sediment deposition reduces limestone weathering
💡 Explanation
Higher soil acidity promotes dissolution because the increased hydrogen ions enhance the chemical weathering by **leaching** of the limestone; therefore, more caves form, rather than being stabilized by temperature or plant roots.
