| Igneous Rock | formed when magma/lava cools |
| Sedimentary Rock | formed when sediments are cemented and compacted |
| Metamorphic rock | Formed by heat and pressure |
| Magma | molten rock under the earth's crust |
| Erosion | the process of sediment being carried by wind, water and ice |
| Weathering | the process of breaking up rocks due to weather |
| Compaction | As the layers build up, they begin to press down on that first layer of sediment, pushing most of the air and water out of it, pushing the particles closer together |
| Deposition | when sediments that are transported to another place and settle |
| Sediments | small pieces of rock |
| Cementation | loose sediments are glued together by natural glues like calcite and silica |
