What type of landslide is characterized by different-sized materials descending by falling, bouncing, and rolling?

The appropriate response is "Rockfalls".

Explanation:

Rockfalls constitute categorized as either a method of landslide consisting of its displacement from such a vertical as well as the sub-vertical plateau of even a sandstone accompanied by rapid descending movement marked by processes of free-falling, jumping, spinning, sometimes slipping. Bedding borders, joints, as well as fractures which always form mechanical inconsistencies, regulate the scale of falling rock blocks as well as cause the blocks to easily break from either the surface or slope.
