Which outcome increases the risk of debris flow collapses in steep fjord valleys following glacial retreat?

💡 Explanation

Reduced vegetation occurs because melting ice exposes unstable slopes causing reduced root cohesion. Biologic root reinforcement strength weakens valley walls; therefore, the probability of landslides increases rather than bedrock stabilizes that is already strong under isostatic pressures.
