Answer:
Rain falling on a slope
Water flowing downhill a region
large rocks and debris on a slope
Mass movement or mass wasting is a process of movement of particles of rocks, soil and other debris down a slope due to the effect of gravitational force acting on these particles. The mass movement or mass wasting occurs due to agents like high speed wind and fast moving water down a slope. Mass movement or mass wasting mainly occur in landslides and mudslides. Rain falling on a slope, water flowing downhill a region, large rocks and debris on a slope are factors which will influence the mass movement of particles.
