Which landform results through freeze-thaw weathering and glacial erosion causing cirque enlargement?

💡 Explanation

When cirque enlargement occurs due to freeze-thaw and glacial quarrying, the backwalls of adjacent cirques erode towards each other because ice erodes the landscape. Therefore arêtes form, rather than eskers, kettle lakes, or drumlins which require different glaciation processes and depositional conditions.
