| Contour Interval | The difference in elevation between two adjacent contour lines of a map. |
| Index Contour | A thicker line marking every 5th contour line of a map. |
| Erosional Features | Earth’s surface that shows evidence of the natural processes of weathering and the removal and relocation of weathered materials. |
| Weathering | The mechanical or chemical processes that break rocks into smaller pieces and sometimes change the chemical composition. |
| Erosion | The process by which water, ice, wind, and gravity remove and transport sediments from one place to another. |
| Sediment Deposition | Occurs when solid fragments of weathered rock are eroded (moved) and then dropped into a new place by wind, water, ice, and gravity. |
