Which outcome results when thermal stress exceeds cohesion limits in high-altitude cirques?

💡 Explanation

Frost wedging causes rock disaggregation in cirques because repeated freeze-thaw cycles expand water in cracks, therefore leading to rockfall, rather than ice accumulation which is precipitation controlled or chemical weathering typical in warmer environment.
