Which outcome occurs when freeze-thaw cycles accelerate corrie erosion?

💡 Explanation

Bergschrunds form as a result of freeze-thaw weathering enhancing glacial erosion. This forms a large crack on steeply sloped cirque walls which increases erosion because the bergschrund facilitates ice wedging, therefore the cirque expands, rather than creating eskers or stratified drift deposits.
