| Weathering | The breaking down of rocks and other materials on the Earth's surface. |
| Erosion | the process of moving sediments by wind, water, ice, or gravity (agents of erosion) |
| Deposition | Process in which sediment is laid down in new locations. |
| chemical weathering | The process in which rock is broken down by changes in its chemical makeup |
| physical weathering | the mechanical breakdown of rocks and minerals |
| Abrasion | when rocks, or other objects, are smoothed due to grinding and tumbling action (physical weathering) |
| Oxidation | A chemical change in which a substance combines with oxygen, as when iron oxidizes, forming rust |
| ice wedging | Process that splits rock when water seeps into cracks, then freezes and expands (physical weathering) |
