Which outcome accelerates soil erosion in Arctic regions undergoing permafrost thaw?

💡 Explanation

When permafrost thaws, the active layer above becomes saturated, reducing soil shear strength, which leads to solifluction – the slow downslope flow of soil as a viscous mass. Therefore, enhanced solifluction amplifies soil erosion rather than changes in fire, chemical weathering, or snow cover affecting erosion to the same extent.
