← GeographyWhich risk notably increases as isostatic rebound lags tectonic uplift in fjord formation?
A)Groundwater aquifer contamination saltwater intrusion
B)Increased bedrock fracturing glacial retreat
C)Landslide generation extreme sedimentation rates✓
D)Methane hydrate destabilization ocean acidification
💡 Explanation
Increased landslide generation increases because differential stress accumulates during isostatic rebound. The resulting rock fracturing due to rebound and deglaciation promotes mass wasting processes/sedimentation, therefore landslides increase. This occurs rather than aquifer contamination, which primarily correlates with hydraulic gradient changes.
