← GeographyWhich mechanism increases coastal erosion rates when a subducting plate causes uplift of the adjacent landmass?
A)Isostatic rebound stresses rock fracturing
B)Increased slope steepness drives landslides✓
C)Hydration weathering weakens unstable cliffs
D)Vegetation removal accelerates soil loss
💡 Explanation
When a subducting plate uplifts the adjacent landmass, increased slope steepness occurs because the angle of repose on the coastline increases, leading to landslides. Therefore landslide risk increases, rather than isostatic rebound, weathering, or vegetation removal each require different destabilization preconditions.
