Which 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.
