| Delta | A formation of sediments that accumalate at the mouth of a large river. |
| Loess | Fine particles of sand and silt that are deposited by wind. |
| Abrasion | The wearing away of rocks by particles carried by wind or water. |
| Gravity | A landslide or mudslide, in which large and small rocks collide with each other and wear away. |
| Water | A liquid that can can disslove most minerals in rocks. |
| Erosion | The process by which products of weathering are moved from one place to another. |
| Waves | The powerful force that constantly erodes and shapes the shoreline. |
| Gullies | The next step after rills in the development of a drainage area. |
| Run Off | Water that runs over the very top of the Earths surface. |
| Temperature | A form of erosion that uses heat and cold. |
| Streams | The next step after gullies in the formation of a drainage system. |
| Rivers | The next step after streams in the formation of a drainage system. This is the last step. |
| Glaciers | A large mass of moving ice and snow. |
| Rills | Tiny grooves, formed by water and sediments that are moving downhill. |
| Oxidation | The process in which oxygen chemically combines with another substance. |
| Deflation | When wind removes particles from the surface and carries them away. |
| Frost Action | The breaking apart of a rock by the continued freezing and melting of water within cracks. |
| Dunes | Formed when wind deposits sand around a rock or bush. |
| Wind Break | Used to slow down wind and to decrease wind erosion. |
| Root-Pry | The breaking apart of rocks caused by the growth of plant roots. |
| Flood Plains | A flat area that is found on both sides of of a river or a stream and is formed by sediments deposited during floods. |
| Sea Caves | A hollowed out potion of a sea cliif. |
| Sea Stacks | A column of resistent rock left behind after a sea cliff has been eroded away. |
| Wind | A fast movement of air. It can cause abrasion. |
| Tributaries | A large stream or small river that flows into an area's main river. |
