Which risk increases where fractured limestone bedrock underlies agricultural land and nitrogen-based fertilizer is heavily applied?

A)Accelerated sinkhole formation, groundwater contamination
B)Surface water eutrophication, reduced infiltration
C)Increased topsoil erosion, dust storms
D)Soil compaction problems, decreased yields

💡 Explanation

_Dissolution_ accelerates sinkhole development and groundwater contamination when acidic runoff infiltrates carbonate bedrock; nitrogen causes chemical weathering, enhancing sinkhole potential rather than soil erosion or surface eutrophication because weathering reactions are happening underground.
