| Rock | A mixture of mineral, volcanic glass, and organic matter |
| Rock Cycle | Shows how rocks slowly change over time |
| Igneous Rock | forms when magma cools and hardens |
| Lava | When magma reaches the earth's surface |
| Intrusive | Rocks that form from magma below the earth's surface |
| Extrusive | Rocks that form from magma on the earth's surface |
| Basaltic Rocks | Dark & dense/ rich in iron and magnesium/ flows freely |
| Grantic Rocks | light/ thick and stiff magma/ high amounts of silica |
| Andesitic Rocks | Combination of basaltic and grantic rocks |
| Metamorphic Rock | Rocks that have changed due to high temperatures or pressures |
| Foliated | When the mineral grains flatten and line up in parallel layers |
| Non-Foliated | Mineral grains grow and rearrange, but they do not leave layers |
| Sedimentary Rock | Form when sediments are presses and cemented together |
| Sediments | loose material such as rock fragments and mineral grains |
