← GeographyWhich geomorphological event is accelerated when discontinuous permafrost thaws?
A)Thermokarst lake formation rates increase✓
B)Esker deposition favors specific drainage
C)Striations indicate glacial direction slowing
D)Kame and kettle topography stabilizes sooner
💡 Explanation
Thermokarst lake formation increases because permafrost degradation results in ground subsidence via thaw settlement involving thermal erosion rather than deposition or altered glacial features. Therefore, increased lake formation is likely rather than stabilization due to melting.
