Which type of mass wasting involves the rapid downslope movement of soil, rock, and debris saturated with water, behaving much like a viscous fluid?

💡 Solution & Explanation

Debris flows involve the rapid downslope movement of earth materials saturated with water, behaving like a viscous fluid due to high water content and steep slopes. Unlike slow processes like soil creep or gravity-driven events like rockfalls and slumps, debris flows travel swiftly through mountain channels.
