Which consequence most directly results when construction disrupts permafrost's active layer?

💡 Explanation

Disrupting the active layer triggers thermokarst because disturbing the insulating surface layer leads to increased ground temperatures, therefore accelerating thaw subsidence rather than altering wave action which is independent, river discharge changes or atmospheric pressure.
