Quizplus · Accepted Answer

Mass movement is the downslope movement of a body of material made up of soil, sediment, or rock propelled by the force of gravity. This includes landslides, rock falls, and debris flows.

Option A (Lahar) is a specific type of mass movement, which involves the downslope flow of water-saturated volcanic ash and debris.

Option B (Downslope flow) is a general term that can refer to any type of fluid motion downhill, including water, mud, or lava. It does not necessarily involve gravity as the driving force.

Option D (Slide) is a specific type of mass movement characterized by a relatively thin, flat layer of material sliding downhill along a well-defined plane or surface.
