Which outcome results from amplified freeze-thaw weathering in cirques?

💡 Explanation

Increased freeze-thaw in cirques causes frost shattering. This mechanical weathering produces more rock fragments, which accumulates as talus slopes because cryogenic action fractures rather than dissolving rock material. Therefore, rockfall increases rather than chemical processes taking place.
