← GeographyIncreased thaw depth impacts hillslope stability due to which mechanism?
A)Active layer detachment✓
B)Frost shattering reduction
C)Glacial isostatic rebound
D)Aeolian sediment stabilization
💡 Explanation
Increased thaw depth causes active layer detachment because the saturated soil loses shear strength, therefore slope failure occurs, involving landslides and debris flows, rather than greater stability via vegetative binding.
