← GeographyWhich outcome occurs when pressurized groundwater flows through fractured limestone?
A)Karst topography and cave formation✓
B)Increased sediment deposition on floodplains
C)Formation of glacial moraines and eskers
D)Enhanced soil fertility due to mineral leaching
💡 Explanation
Karst topography develops because dissolution occurs; slightly acidic groundwater dissolves the limestone along fractures, enlarging them into caves and sinkholes. This landscape forms due to chemical weathering, therefore cave formation, rather than deposition or glacial features.
