← GeographyWhich risk increases when urban development overlays karst regions?
A)Increased likelihood of subsurface sinkhole collapse✓
B)Decreased surface albedo and heat retention
C)Diminished groundwater recharge capabilities overall
D)Heightened concentration of surface particulate matter
💡 Explanation
Increased surface loading from construction accelerates limestone dissolution via solution weathering, because added pressure overwhelms the rock's load-bearing capacity, therefore causing unpredictable sinkhole collapses; rather than uniform subsidence from overburden spreading.
