Which feature results when ice mass wanes inside a cirque?

💡 Explanation

The formation of a tarn occurs because glacial erosion in a cirque creates a depression, which is then typically filled with meltwater forming a lake; therefore a basin remains rather than esker deposition following a subglacial tunnel.
