| Ore | A mineral deposit large and pure enough to be mined |
| Talc | softest mineral on Moh's scale |
| Tool | something that helps you do a task |
| Theory | An explanation for a range of hypotheses and observations supported by testing |
| Stratification | sedimentary rock is formed through this process |
| Save lives | learning to predict tornadoes is an example of how science can |
| Temperature & Pressure | has to increase for metamorphism to occur |
| Silicates & Nonsilicates | the two major groups of minerals |
| Science | knowledge gained by the natural world |
| Silicon & Oxygen | A silicate mineral mus contain |
| Impurities | Besides air and water, what can change the color of a mineral |
| Streak | the color of the powder that a mineral leaves on a piece of white, unglazed porcelain is called a mineral's |
| Scientific methods | help us answer questions |
| Gemstones | the name for nonmetallic minerals that are valued for their beauty and rarity rather then their usefulness |
| Metamorphic Rock | When sedimentary rock is exposed to heat & pressure, it changes into |
| Igneous Rock | forms during the rock cycle when magma cools |
| Asking a Question | the first step of the scientific method |
| Coarse-grained | the texture of igneous rock when magma cools slowly |
| Diamond | the mineral that is most resistant to scratching |
| Crystalline Structure | a repeating pattern of atoms, ions, or molecules in a mineral |
| Controlled Experiment | tests only one factor at a time |
| Beginning any science investigation | it is important to become familiar with safety symbols |
| Mass | the amount of matter that makes up an object |
| Fine-grained | the texture of an igneous rock when magma cools rapidly |
| Erosion | a process that changes rock on earth's surface |
| Composition & Texture | scientists classify rocks by |
| Strata | layes in sedimentary rock |
| Changes in composition | magma is formed by |
| Chemical composition | the groupings silicate and nonsilicate minerals are based on |
| Weathering | forms sediment |
