Which type of mass wasting involves the rapid downslope movement of saturated soil, rock debris, and mud behaving like a viscous fluid, commonly triggered by heavy rainfall or volcanic activity?

💡 Solution & Explanation

Mudflows represent a form of mass wasting where water-saturated soil and debris flow rapidly down slopes like a viscous fluid, frequently triggered by heavy monsoon rains or volcanic lahars. Soil creep is an extremely slow downward movement of soil particles, rockfall involves free-falling blocks, and slump describes rotational slipping along a curved rupture surface.
