| Minerals Galore |
| #1 |
How do minerals form? |
in the mantle, at or near the surface, from mineral-rich water |
| #2 |
Name 3 Mineral Properties |
streak, luster, hardness |
| #3 |
How are minerals are used? (at least 3 ways) |
jewelry, coins, metal containers, plaster, construction materials |
| #4 |
Give me an example of a mineral and a way that this mineral is used. |
Copper, used in jewelry, electrical wiring, musical instruments |
| #5 |
Explain how you would test the minerals to find the diamond. |
test the minerals to find the diamond, only the diamond will scratch all the other crystals |
| Rocks, Rocks, and More Rocks |
| #1 |
What causes igneous rocks to form? |
when melted rock hardens |
| #2 |
How are sedimentary rocks formed? |
when sediments are compressed and hardened |
| #3 |
How are metamorphic rocks formed? |
when other rocks are changed by heat and pressure |
| #4 |
7. Sometimes molten lava from a volcano flows into the ocean. Do you think the rock that forms when the lava is cooled by ocean water is fine-grainer or coarse-grained? Why? Explain your thinking. |
fine-grained because it cools very fast |
| #5 |
8. Compare and Contrast two types of rocks. You may choose two of the three types of rocks to compare and contrast. Select two: igneous, metamorphic, sedimentary |
Accept reasonable answers |
| Rock Cycle: I'm seeing cycles |
| #1 |
What are some of the causes of weathering? |
tree roots growing into the rock, edges are rounded, sediments are compacted together, ice/wind/rain affecting rocks |
| #2 |
What are some of the effects of weathering? |
rock broken into bieces, rocks change, etc. |
| #3 |
A rock that is made of small grains. How can you tell whether it is igneous or sedimentary? |
A sedimentary rock will probably be softer and may be easier to break. |
| #4 |
How might a sandstone change into another sandstone? Explain. |
A sandstone can be weathered and eroded. The rock and mineral bits can then become compacted and cemented to form another sandstone. |
| #5 |
Why do scientists classify minerals? Explain. |
Classification is a way to organize information. Forming minerals into groups makes it easier to study and learn about minerals. Once minerals have been classified, conclusions can be drawn about how they are related and their physical or chemical properties. |
