| Igneous Rocks | formed by melting, Cooling Crystalizing |
| Sedimentary Rocks | formed by Weathering, Transportation, Deposition, Compaction, and Cementation |
| Metamorphic Rocks | Formed by heat and/or pressure and/or chemicals |
| Intrusive Igneous | Formed underground |
| Extrusive Igneous | Formed above ground |
| Oceanic igneous | Denser and darker colored |
| Continental igneous | Light in color and density |
| Cools slowy | Forms large crystals |
| Cools quickly | Forms small to no crystals |
| Heat by contact | Transforms due to touching something hot |
| Heat by area | Deeper in the earth where the temperatures are greater |
| Magma | Liquid rock underground |
| Lava | Liquid rock above ground |
| Sources of pressure | Being deep underground or being transformed by moving plates |
| Chemicals | Exposure to certain substances transforms a rock |
| Weathering | Broken into small bits by wind, water, or ice |
| Transportation | Small rock bits are carried by wind water or ice |
| Deposition | Moving rocks come to rest |
| Compaction | Rock bits being squeezed together |
| Cementation | Rock bits are held together by minerals left behind as water evaporated |
