| Abrasion | Wearing away of solid particles carried by |
| Root-Pry | The breaking aprt of rocks caused by plant roots |
| Chemical Weathering | Weathering that involes changes in the chemical make-up of rocks |
| Mechanical Weathering | Weathering that does not involove changes in the chemical make-up of rocks |
| Wind | Most coomon form of erosion in the desert |
| Loess | Accumulations of the fine particles of sand deposited by wind |
| exfoliation | The Breaking off of curved sheetsParallel to a rocks surface |
| Frost Action | The breking of rocks cuased by water freezing |
| Gravity | Pulls loosened rocks down a mountain cliff in a landslide |
| Running Water | The major cause of erosion |
| Deflation | Erosion caused by the wind removing loose material such as sand, silt, and clay |
| Mass Wasting | The downhill movement of sediments due to gravity |
| Landslide | A large downhill movement of loose rocks and soil caused by gravity |
| Plant Acids | Some plants produce weak acids which can dissolve certain materials |
| Deposition | The process by which sediments are laid down in new locations |
| Soil Creep | Slowest type of mass wasting |

| Drainge System | The network of streams and other bodies of running water that ultimaly drain into an area's main river |
| Sulferic Acid | In places where there is surfur oxides in the air, acid rain can be produced |
| Carbonation | The process in which carbonic acid reacts chemically with other substances |
| Oasis | A place in the desert that is fertile because it has a supply of water |
