| Weathering | Process of rocks in Earths crust slowly being broken into smaller pieces. |
| Erosion | Process of carrying away weathered bits of rock |
| Deposition | Laying down of pieces of rock during erosion. |
| Landform | A natural land feature on earths surface. |
| Physical weathering | Rocks are broken into smaller pieces of the same kind of rock. |
| Igneous rocks | Rocks that form from molten rock. |
| Hardness | How easily the surface of a mineral can be scratched. |
| Earthquakes | The sudden movement that causes Earths crust to shake |
| Volcanoes | A landform that forms at an opening in Earths crust where magma reaches the surface. |
| Landslides | The rapid downhill movement of a large amount of rock and soil. |
| Glaciers | A large body of slowly moving ice. They form when more snow falls than melts in an area. |
| Chemical weathering | Chemicals cause rocks to change into different materials and break down. |

| Precipitation | Any form of water that falls to earth. |
| Water cycle | The movement of water from earths surface to the atmosphere and back again. |
| Minerals | Natural, no living solid crystals that make up rocks. |
| Fault | A break or crack in rocks where Earths crust can move suddenly. |
| Epicenter | The point on earths surface that is directly above the focus during earthquakes. |
| Metamorphic rocks | Rocks that have changed as a result of heat and pressure. |
| Cleavage | Property of minerals to break along smooth flat surfaces. |
