The document discusses different types of mass movements that occur on slopes due to gravity. There are 5 main factors that influence mass movements: slope angle, material weight, material resistance to movement, triggers like earthquakes or heavy rain, and water. The types of mass movements described are creep, flows, slides, slumps, and avalanches. Creep is a slow movement down slopes of all angles. Flows such as earth flows and mud flows involve thicker, more liquid movements that can be triggered by vibration or rain. Slides such as rockslides or landslides are rapid movements with little mixing of materials that may be triggered by earthquakes. Slumps and avalanches also involve the downslope movement of materials.
