<span>There are different types of mass movements. They are: 1. rockfall--free falling of rocks or debris of rocks from a steep cliff. 2. mudflow--commonly known as mud slides. This is another form of slope movement a proportion of clay and debris rapidly flow. 3.landslip/landslide--is a mass movement that involves a great range of ground movements. This can happen under water,at the coast or even on shore. 4. slump--happens along a curved surface over a short distance.5. soil creep--also known as downhill creep. This is a slow progression of rocks downward. Therefore, the answer to this question is "slump".</span>
