Which outcome occurs when a periglacial lake thaws?

💡 Explanation

Thermokarst forms because thawing permafrost weakens the ground, causing subsidence via thaw settlement. Frost heave destabilizes because reduced ground strength creates an unstable landscape rather than stable glacial accumulation or increased weathering.
