| erosion | movement of products of weathering |
| cooling | change in temperatureafter removal of heat |
| cementation | sediment is glued together |
| rock cycle | series of changes from one rock type to another |
| magma | molten rock inside Earth |
| heat | thermal energy transferred from one object to another |

| igneous | "born of fire" rock |
| melting | changing from a solid to a liquid |
| sedimentary rock | rock type formed from sediment being deposited, squished and glued |
| weathering | breaking down rock by chemical or physical means |
| metamorphic rock | rock type formed by heat and pressure |
| deposition | the laying down of sediment |
