Which outcome occurs when ice wedges diminish cirque walls?

💡 Explanation

Increased rockfall and headwall retreat occurs, which is due to freeze-thaw weathering because ice wedges expanding and contracting in bedrock fractures causes rock weakening; therefore, rockfall increases rather than consolidation because weathering disintegrates the rock fabric.
