| Plate | a large section of the earths surface made of the crust and the rigid top part of the mantel |
| Plate Tectonics | a teary state in the earths surface is broken into a plate that moves |
| Mineral | a natural non living solid with a definite chemical structure |
| Rock Cycle | the way rocks change from one form to another |
| Atmosphere | layer that gasses are found |

| Center most layer of the earth | core |
| Middle layer of the earth | Mantle |
| Outside layer of earth | Crust |
| Hypothesis that continents have moved | edges and features don't match |
| Events that cause plate movement | earth quake, fault |
| Where do most earthquakes and volcanic eruptions occur on earth? | Hawaii |
| How do volcanoes form islands? | they explode into water, the lava and water form islands. |
| Example of weathering | iron to rust |
| Example of erosion | wind and weather and ice |

| Sedimentary Rock | rock formed when elements are pressed or cemented together. |
| Igneous Rock | rock formed from melted rock that comes from deep with in the earth. |
| Metamorphic rock | a rock formed when igneous or sedimentary rocks are changed by heat or pressure. |
| Why do scientists study layers of rock | to study what has changed from the past. |
