| Erosion | process that wears away surface materials and moves them from one plae to another |
| Deposition | dropping of sediments that occurs when water, wind, or glaciers lose their energy and can no longer carry the load |
| Mass Movement | any kind of erosion in which gravity moves sediments downhill |
| slump | a mass movement that occurs when a mass of materials slips down a curved surface |
| creep | occurs when soils move slowly downhill |
| glacier | large mass of ice and snow moving on land under its own weight |
| plucking | action in which a moving glacier picks up loose pieces of rock |
| till | mix of different size sediments that is deposited from the base of a glacier as it retreats |
| moraine | ridge of rocks and soil deposited by a glacier when it stops moving |
| outwash | material deposited by the water from a melting glacier |
| abrasion | type of erosion that occurs when windblown sediment scrapes and wears away rock |
| deflation | occurs when wind removes small particles of sediment from the land and leaves heavy pieces of sediment behind |
| dune | mound of windblown sediment that piles up behind an object |
| loess | deposits of very fine-grained soil carried by the wind |
