← GeographyWhich consequence results when overlying clay erodes, exposing fractured limestone?
A)Accelerated sinkhole formation process✓
B)Increased regional seismic activity
C)Enhanced evaporite mineral deposition
D)Widespread coastal marine transgression
💡 Explanation
Exposing fractures accelerates sinkhole formation because infiltrating water dissolves limestone via chemical weathering known as dissolution; therefore a sinkhole develops rather than a stable surface, because clay prevents direct dissolution whereas seismic activity involves plate tectonics.
