Which feedback mechanism accelerates cirque formation in alpine glacial environments?

💡 Explanation

When cirques enlarge; reduced albedo occurs, because ice exposes darker bedrock enhancing solar absorption, increasing temperatures and melting, accelerating glacial erosion and expansion. Therefore, reduced albedo accelerates cirque formation, rather than enhanced ice, or decreased stabilisation which has damping effects.
