Which of the following types of mass wasting events involves the rapid, saturated downslope flow of earth material that behaves like a thick, viscous fluid?

💡 Solution & Explanation

A mudflow is a rapid mass wasting process involving saturated earth material flowing downslope like a viscous fluid, typically triggered by heavy rainfall. Rockfall involves free-falling rock fragments, whereas soil creep represents an extremely slow movement of surface material. Mass movement processes form an essential component of physical geography syllabi.
