← GeographyWhich outcome occurs when concentrated animal feeding operations generate excessive nitrogen runoff on karst topography?
A)Accelerated sinkhole formation and aquifer contamination✓
B)Increased soil fertility and reduced erosion
C)Enhanced carbon sequestration in limestone
D)Decreased groundwater flow and salinity
💡 Explanation
Sinkhole formation accelerates via dissolution because enriched nitrogen runoff acidifies groundwater, enhancing chemical weathering of bedrock. Therefore, sinkholes form rapidly, rather than a slower formation otherwise due to natural carbonic acid levels.
