← GeographyWhich outcome results when thaw cycles in permafrost increase rate of solifluction?
A)Increased sediment flux to valley floors✓
B)Enhanced carbon sequestration in peatlands
C)Saltwater intrusion into coastal aquifers
D)Stabilization of alpine vegetation communities
💡 Explanation
When thaw cycles accelerate in permafrost regions, solifluction, the slow downslope flow of saturated soil, increases because the active layer thickens and pore water pressure builds, enhancing mass wasting. Therefore sediment flux increases, not carbon sequestration, sea water intrusion, or vegetation stabilization, which require different conditions.
