On valley flanks in mountainous areas, which erosional outcome results from intense freeze-thaw cycles?

💡 Explanation

Glacial cirque formation occurs because nivation, amplified by differential weathering, leads to the erosion of bedrock; therefore, a bowl-shaped depression forms, rather than fluvial or depositional landforms forming from meltwater.
