← GeographyWhich geomorphological result stems from limestone cave roof collapse?
A)Formation of steeper escarpments
B)Development of polygonal patterned ground
C)Establishment of wider meandering valleys
D)Production of extensive surface sinkholes✓
💡 Explanation
Surface sinkholes develop due to the mechanism of Karst dissolution, wherein the chemical weathering of carbonate rocks causes subterranean voids; because the caves no longer support the overburden, collapse occurs, therefore sinkholes appear, rather than other terrain features related to glaciation or tectonic lift.
