Which outcome is most likely when rising Arctic permafrost temperatures increase active layer thickness on sloped terrain?

💡 Explanation

When the active layer thickness increases, solifluction occurs because thawed soil loses strength and flows downslope under gravity, increasing sediment transport. Therefore, increased sediment transport occurs rather than decreased stability, reduced porosity, or enhanced vegetation, which depend on different permafrost processes.
