Which type of mass wasting involves a sudden, rapid down-slope movement of saturated rock debris, soil, and mud behaving like a viscous fluid?

💡 Solution & Explanation

A debris flow is characterized by a rapid, fluid movement of water-saturated earth, rocks, and organic material down a slope, behaving dynamically like a viscous mudslide. Soil creep represents an extremely slow and imperceptible downward movement, whereas rockfalls involve free-falling rock fragments through the air. These destructive flows commonly occur in mountainous terrain following heavy monsoon downpours or seismic disturbances.
