| Definition | The process of transporting and removing weathered rock and soil particles from their original location by natural agents like wind, water, ice, or gravity. | The process of breaking down rocks and minerals in situ (in place) without the removal of material. |
| Location | Occurs during the movement of material from one place to another. | Occurs where rocks and minerals are located, without significant movement. |
| Processes | Physical transportation and removal of weathered material. Common agents include wind, water, ice, and gravity. | Physical or chemical breakdown of rocks and minerals. Includes mechanical (physical) and chemical processes. |
| Outcome | Results in the relocation and deposition of weathered material in new locations. | Transforms the composition and physical characteristics of rocks over time. |
| Agents | Natural agents such as rivers, glaciers, wind, ocean waves, and gravity play a significant role in erosion. | Agents include physical forces (e.g., freeze-thaw cycles, abrasion) and chemical reactions (e.g., dissolution, oxidation). |
| Transported Material | Involves the movement of weathered rock and soil particles, such as sediment, sand, or pebbles. | Does not involve the movement of material; weathered rocks remain in place. |
| Resulting Landforms | Creates landforms such as river valleys, canyons, deltas, sand dunes, and sediment deposits. | Alters the composition and physical properties of rocks, potentially making them more susceptible to erosion. |
