Which risk increases due to freeze-thaw cycles around a cirque?

💡 Explanation

Increased freeze-thaw action enhances rockfall and slope stability because frost wedging widens cracks, saturates, and destabilizes the rock faces surrounding the cirque through mechanical weathering; therefore rockfall risk increases rather than chemical weathering or changes to ice accumulation.
