← GeographyWhich outcome arises when groundwater saturates fractured limestone?
A)Karst topography landscape formation accelerating✓
B)Increased silica precipitation within aquifers
C)Elevation of regional groundwater salinity
D)Reduced sediment compaction in shale layers
💡 Explanation
Karst topography forms due to chemical weathering via dissolution because carbonic acid in groundwater dissolves calcium carbonate in limestone, which creates sinkholes and caves affecting the landscape; therefore, karst accelerates rather than inhibiting silicification.
