Which outcome occurs when permafrost thaw increases rates of pedogenesis?

💡 Explanation

Increased permafrost thaw accelerates soil formation via cryoturbation, leading to mobilization of previously frozen soil particles; this leads to slope instability and higher rates of coastal erosion and landslides because soil cohesion deteriorates therefore increasing erosion risk rather than stabilizing the existing landscape.
