| Rock | A mixture of glass, organic material and minerals |
| Igneous | A type of rock that is made from molten rock |
| Sedimentary | A type of rock that is made up from sediments of other rocks or made chemically |
| Metamorphic | A type of rock that is created from other rocks that have been subjected to extremem heat and pressure |
| Extrusive | A type of igneous rock that has large crystals because it cooled slowly inside the Earth |
| Intrusive | A type of igneous rock that has small crystals because it cooled quickly outside the Earth |
| Clastic | A type of sedimentary rock that is made up from sediments of other rocks |
| Non-clastic | A type of sedimentary rock that is made chemically |
| Foliated | A type of metamorphic rock that has layers or bands of minerals on it |
| Non-Foliated | A type of metamorphic rock that does not have lines or bands |
| Rock Cycle | A diagram that shows how rocks are recycled and change from one to the other |
| Weathering and Erosion | Processes that help wear down rocks to create sediment |
| Compaction and Cementation | Processes that take sediment and then create a sedimentary rock from that sediment |
| Melting | Process where rocks turn back into magma |
| Cooling | Process where rocks are created out of magma |
| Heat and Pressure | The two things needed to make a metamorphic rock |
