| weathering | causes rocks to change and crumble |
| mechanical weathering | breaks rocks into smaller pieces without changing them chemically |
| chemical weathering | breaks down rocks by changing chemical composition |
| soil | mixture of weathered rock organic matter, water and air |
| erosion | wearing away and removal of rock material |
| mass movement | gravity causes rock or sediment to move down a slope |
| deflation | removal of small loose particles of rock by wind |
| abrasion | sandblasting of rocks by wind born particles |
| runoff | flow of water over earth's surface |
| glacier | snow that accumulates to form a large deep mass |
| streams | most important agent of erosion |
| slump | occrs when a mass of rock or sediment move down hill along a curved surface |
| creep | when sediments move down hill |
| causes sand bar, delta, and gully | water |
| causes sand dune and loess | wind |
| causes till and cirque | ice |
| causes rockslide, and slump | gravity |
| what is not an example of mass movement | abrasion |
| chemical weathering takes place fastest in what kind of climate | hot and wet |
| soil forms rapidly in what kind of climate | tropical |
| what happens to the deposition if a stream slows down | it increases |
| rich soil is often found under what | grassy lands |
| cirques are caused by what | glaciers |
| Gravity causes what | mass movement |
