Section 5 Vocab
| Atmosphere | the envelope of gases surrounding the earth or another planet. |
| Biosphere | the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms. |
| Geosphere | any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere. |
| Hydrosphere | all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds. |
| Dependent Variable | is the event studied and expected to change whenever the independent variable is altered. |
| Independent Variable | variation does not depend on that of another. |
| Hypothesis | proposed explanation made on the basis of limited evidence as a starting point for further investigation. |
| Scientific Law | a statement based on repeated experimental observations that describes some aspect of the universe. A scientific law always applies under the same conditions, and implies that there is a causal relationship involving its elements. |
| Scientific Theory | a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. |
| Cleavage | A clean break on a mineral |
| Fracture | A jagged break |
| Hardness | How hard a mineral is |
| Luster | How florescent a mineral is |
| Streak | the colour of the mineral when it is powdered |
| Fractional crystallization | the removal and segregation from a melt of mineral precipitates; except in special cases, removal of the crystals changes the composition of the magma. |
| Partial Melting | Minerals that melt before others; creating a slush like substance |
| Pegmitite | a coarsely crystalline granite or other igneous rock with crystals several centimeters to several meters in length. |
| Compare and contrast mass and weight. | Mass is how much there is inside of it, weight is how heavy it is. They are both measurements |
| Mineral- a naturally occurring, inorganic solid with a specific chemical composition and a definite crystalline structure”. | Naturally occurring - happens in nature inorganic solid - not organic Specific Chemical Composition - chemicals it is composed of definate crystalline structure - it is a crystal |
| Explain what physical properties could be used to tell the difference between Pyrite (Fool’s Gold) and Gold. | Check the streak, pyrite's will be green instead of yellow. |
| 5. Given the harness of two different minerals and explain what would happen if they were rubbed together. | One of them will more than likely scratch |
| 6. Explain how igneous rocks form. | Hardened lava |
