| carbonic acid | A weak acid formed when carbon dioxide dissolves in water. |
| chemical weathering | The breaking down of rock through chemical change. |
| creep | Slow, imperceivable, downhill movement of soil. |
| erosion | The process of transporting earth materials through natural agents. |
| exfoliation | Peeling of a surface layer of exposed rock. |
| hydrolysis | A chemical reaction of water with another substance. |
| ice wedging | A type of mechanical weathering. When water that has gotten into cracks in earth material freezes. The ice expands, pushing apart the material. |
| landslide | The sudden movement of earth materials downhill. |
| topsoil | The A horizon of soil that contains humus. |
| subsoil | The B horizon of soil, below the A horizon. |
| soil profile | A cross-section of soil horizons from the surface to the bedrock. |
| soil | Material consisting of loose, weathered rock particles, and organic materials in which plants can grow. |
| residual soil | Soil formed from the breaking down of bedrock material. |
| parent material | (Different from radioactive Parent Material) It's just the material that was processed into soil. |
| oxidation | When oxygen reacts with other substances. |
| mass movement | When lage masses of Earth Material move downslope. |
| transported soil | Soil that has been deposited by the action of wind, waves, water, etc. |
| mechanical weathering | The physical breakdown of earth materials that results in no chemical change, just a change in size. |
| weathering | The process by which earth materials such as rocks are broken down by action of weather, wind rain, water, or organisms. |
| mudflow | A rapid movement of mud. Mud = water saturated clay and/or silt. |
| Sediments | Weathered particles of rock that vary in size. Clay, silt, sand, and pebbles are examples. |
| Deposition | When and were sediments are "put" in a place. |
| Erosion 2 | When and where sediments are "taken" from a place. |
