| sediment | loose materials, such as rock fragments that have been moved by erosional forces |
| erosion | surface materials are worn away and transported from one place to another by wind, water, and glaciers |
| deposition | dropping of sediments that occurs when an agent o erosion loses its energy and can no onger carry its load |
| mass movement | any type of erosion that occurs as graity moves materials down-slope |
| slump | type of mass movement, a mass of material moves down a curved slope |
| creep | mass movement, sediments move down slope very slowly |
| rock slide | layers of rock slide downslope suddently |
| mudflows | after a heavy rain water mixes with sediment causing it to flow downhill |
