Which outcome occurs when permafrost melts in landscapes?

💡 Explanation

Increased solifluction leading to surface instability occurs, because melting permafrost saturates the active soil layer promoting downslope movement due to gravity’s pull and reduced sheer strength. Therefore, land becomes unstable, rather than undergoing carbon sequestration because organic-rich material decomposes when thawed.
