Which glacial outcome results from freeze-thaw weathering expanding cirques?

💡 Explanation

Freeze-thaw action enlarges and deepens the cirque, creating a bedrock depression due to nivation. Meltwater then accumulates. This deepening results in a tarn lake at the base of the cirque, therefore a lake forms, rather than increased pressure within the ice.
