MINERALS
| Question | Answer |
|---|---|
| mineral | A naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition. |
| inorganic | The "I" in SNIFC (means "non-living"). |
| crystal | The "C" in SNIFC (has flat sides called faces that meet at sharp edges and corners). |
| streak | The _____ of a mineral is the color of its powder. |
| luster | The term _____ is used to describe how light is reflected from a mineral's surface. |
| density | Defined as mass in a given space, or mass per unit volume (mass divided by volume). |
| solid | The "S" in SNIFC (represents a phase/state of matter). |
| natural | The "N" in SNIFC (means not man-made). |
| fixed | The "F" in SNIFC (means a definite/unchanging chemical composition--"recipe"). |
| diamond | What is the hardest known mineral? |
| cleavage | A mineral that splits easily along flat surfaces has this property. |
| fracture | This describes how a mineral looks when it breaks apart in an irregular way (does not split apart evenly). |
| hardness | This scale ranks minerals from softest (#1) to hardest (#10). This can be determined by a scratch test. |
| water | Minerals can form in two ways: by crystallization of magma/lava or by crystallization of materials dissolved in _____. |
| cool | One factor that determines the size of crystals is the rate at which magma/lava or solutions _____. |
| true | TRUE or FALSE? Minerals form rocks. |
| crust | The rigid, rocky outer surface of the Earth (thinner under the oceans). |
| mantle | A liquid, rocky layer located under Earth's crust. |
| true | TRUE or FALSE? Since most glass is man-made, it is NOT a mineral. |
| false | TRUE or FALSE? Even though coal is a fossil fuel, it's still considered a mineral |
| true | TRUE or FALSE? Observing/recording the color of a mineral is helpful but not reliable. Other testing needs to occur to properly name/ID the mineral. |
| crystal | A solid whose atoms or molecules are arranged in a regular, repeating pattern. |
| solid | A mineral is always a(n) _____ because it has a definite volume and shape. |
| gold | An example of a mineral made up of a pure element on the Periodic Table is _____. |
| true | TRUE or FALSE? If you broke a mineral into tiny pieces, each piece would still show the same crystal structure. |
| fracture | This term describes when a mineral does NOT break along flat surfaces but rather breaks unevenly into pieces that have curved or irregular surfaces. |
