Which type of mass wasting involves the rapid movement of a mass of rock, debris, or earth down a slope along a planar surface?

💡 Solution & Explanation

A rockslide involves the rapid downward movement of rock masses along a distinct planar or slip surface. Creep describes extremely slow slope movement, while solifluction occurs in permafrost regions due to soil saturation. Mudflows involve saturated fine-grained materials behaving like fluid slurries.
