Question

Quizplus · Accepted Answer

Debris flows are the most serious mass wasting hazards in mountain valleys, as they involve a rapid movement of a mixture of water, rock debris, and soil down steep slopes in narrow valleys, posing high risk to communities and infrastructure downstream. Airborne rockslides, glacier bursts, and rock bursts are also mass wasting hazards in mountain valleys, but are less common and typically affect smaller areas.
