Which effect accelerates when thaw-freeze cycles saturate soils on a hillslope underlain by permafrost?

💡 Explanation

When thaw-freeze cycles saturate soils over permafrost, the process of solifluction intensifies because lubrication from meltwater leads to increased downslope soil creep due to gravity. Therefore solifluction lobe formation is accelerated, rather than albedo decrease, weathering rate elevation, or carbon sequestration enhancement which depend on differing mechanisms.
