← GeographyWhich mechanism creates stepped waterfalls within karst caves?
A)Differential dissolution of bedrock layers✓
B)Seasonal shifts in groundwater table
C)Erosion by trapped sediment deposits
D)Tectonic subsidence and localized fracturing
💡 Explanation
Differential dissolution produces cave features because variations in the chemical resistance of bedrock layers result in varied erosion rates; therefore, waterfalls form at the more resistant layers, rather than uniform or sediment erosion processes.
