Which process accelerates cirque formation when meltwater accumulates in the bergschrund?

💡 Explanation

When meltwater fills the bergschrund of a cirque, frost wedging accelerates because pressure fluctuations from repeated freeze-thaw cycles fracture the rock. Therefore frost wedging via pressure fluctuations results, rather than other glacial processes which require different conditions than pressurized meltwater within the crevasse.
