Which risk increases when ice mass loss steepens cirque walls?

💡 Explanation

Increased steepness elevates gravitational potential energy which is a trigger parameter; therefore rockfall frequency heightens because steeper slopes promote slope instability by exceeding the angle of repose, rather than climate weathering or ocean cycles.
