Which outcome results when melting permafrost destabilizes slopes?

💡 Explanation

Thermokarst lakes form due to thermal erosion; the melting creates depressions filled with water accelerating thaw because lake water transfers heat more effectively, therefore, the lake expansion enhances the slope instability rather than other stabilizing effects.
