| Igneous | Rock type formed when molten magma cools and solidifies |
| Granite | An example of an igneous rock with large crystals. Used for work surfaces and gravestones. |
| Basalt | An example of an igneous rock with small crystals |
| Small crystals | Formed whem magma cools quickly |
| Large crystals | Formed when magma cools slowly |
| Sedimentary rocks | Usually granular, with layers and fossils. Formed by sedimentation. |
| Metamorphic rocks | Rock type formed by heat and pressure acting on other rocks. |
| Igneous rocks | contain crystals, no layers and no fossils |
