| Term | Definition |
|---|---|
| Physical Weathering | Rocks are broken down into smaller pieces but the composition of the rocks remain the same |
| Chemical Weathering | Reactions break down the bonds that hold rocks together, forming new substances |
| Erosion | Processes by which wind, water, ice or gravity transport weathered materials from one location to another ("Takes It") |
| Weathering | The breaking down of rocks and other materials on the Earth's surface by physical or chemical processes ("Breaks It") |
| Deposition | Process in which sediment is laid down in new locations ("Drops It") |
| Examples of Physical Weathering | Freezing/Thawing, Animal Actions, Plant Roots, Running Water, Wind Abrasion, Changes in Heat |
| Examples of Chemical Weathering | Reactions with Oxygen (Rust); Acid Rain; Reaction with materials creating new substances |
| Sediment | Crushed rock and rubble formed when weathering occurs |
| Oxidation | The reaction of rock minerals with oxygen resulting in rust |
| Carbonation | The reaction of rock minerals with carbonic acid |
| Hydrolysis | The reaction of rock minerals with water |
| Wind Abrasion | Wind carries small particles that sandblast the surface of rocks as they move |
| Acid Rain | Any form of precipitation that contains high levels of acidic components like sulfuric and nitric acids which leads to chemical weathering |
