Which risk increases when a cirque's bergschrund melts?

💡 Explanation

Melting of the bergschrund increases the risk of moraine sediment mass wasting within the cirque due to reduced support; regelation contributes to freeze-thaw cycles. Therefore surface material instability causes erosion, rather than outburst floods dependent on subglacial processes.
