Which factors can lead to a mass movement? Check all that apply.steep slopesremoval of vegetationdepositionanimal activityearthquakesundercutting of a slope

Mass movement happens when gravity pulls soil or rock downhill, especially when a slope becomes less stable. Steep slopes, removal of vegetation, earthquakes, and undercutting can all increase instability or trigger movement. Deposition is the buildup of material, not usually a cause of mass movement; animal activity is not considered a major general trigger here.
