| Frost Wedging | When liquid water fills cracks in rocks and freezes causing expansion which results in the rock breaking down into sediment |
| Weathering | the breakdown of rock into sediment |
| Metamorphic | formed from heat and pressure-usually has distorted bands running through it |
| Erosion | the movement of sediment to a new location |
| Chemical Weathering | Any of the various weathering processes that cause exposed rock to undergo chemical decomposition |
| Physical Weathering | Also known as mechanical weathering, is the process by which rocks break down through natural means |
| Biological Weathering | Living organisms such as plants and animals cause rock to decompose |
| Exfoliation | to remove the top layer of rocks or soil due to weathering and erosion |
| Thermal Expansion | rocks breaking down due to heat making them expand and break |
| Dissolution | Acidic water eats rock away causing weathering and erosion |
| Hydrolysis | the softening of the rock feldspar into clas |
| Oxidation | when iron meets oxygen and moisture causeing rust |
| Sedimentary | Rocks formed from erosion, deposition, compaction, and cementation |
| Lichen | Small plant looking fungi that attaches onto rocks aiding weathering and erosion |
| Igneous | Rocks formed from melting and cooling |
| Humus | decayed organic material usually covering a forest floor |
