Which feedback loop controls the size of glacial cirques?

💡 Explanation

Cirque size stabilizes when erosion slows; accelerated freeze-thaw weathering at its headwall increases erosion, therefore the cirque grows until armoring occurs, rather than vegetation directly influencing cirque headwall erosion rates.
