← GeographyWhich pattern commonly results where loess deposits overlie karst topography?
A)Increased surface subsidence incidents✓
B)Accelerated surface weathering rates
C)Decreased regional seismic activity
D)Reduced groundwater recharge rates
💡 Explanation
When loess sits atop karst, infiltrating water dissolves the underlying limestone, causing subsurface cavities because this chemical weathering weakens overall structure. Therefore, increased *compaction* becomes more likely, rather than increased weathering elsewhere.
