| Extrusive rocks | Igneous rocks formed on the surface of the earth |
| Intrusive Rocks | Igneous rocks formed under the earth's surface |

| Clastic Sedimentary | rocks t5hat are formed when broken pieces of roks are squeezed and cemented together back into new rocks |
| no-clastic Sedimentary rocks | rokcs that are formed from parts of rocks, and with a chemical process turn into new rocks |
| Limestone | a type of sedimentary rock |
