Which risk increases as melting permafrost destabilizes slopes?

💡 Explanation

Increased slope instability, due to thaw-induced weakening, leads to increased debris flow. This debris flow activity increases because the gelifluction destabilizes previously stable soil, therefore producing these mass wasting events, rather than promoting esker formation which instead require glacial meltwater.
