Which geologic consequence directly follows the continued glacial erosion within a cirque?

💡 Explanation

When a glacier erodes within a cirque, glacial plucking and abrasion deepen the basin because ice freeze-thaw action weathers rock, leading to a deepened hollow which later fills with meltwater. Therefore, a tarn lake forms, rather than braided streams, eskers which are features of glacial deposition, or karst landscapes resulting from limestone dissolution.
