1. Minerals
Minerals touch our lives in hundreds of ways everyday-we could not live without them!

2. We use minerals to
Growing food, tractors, water pipes, electrical wiring, refrigerator, radio, toaster, lamp, light bulbs, sheets, towels, clothing, make up, fireworks, soap and toothpaste, windows; cereal bowls and dishes, glasses and cups, faucets, doorknobs, electronics; cars, trucks, ships, and railroad cars; bricks, tiles, siding, and houses-Every part of our lives depends on minerals.

3. Minerals must be mined from the Earth.
We use 2 billion tons of minerals each year in the US. That’s 10 tons of minerals for every man, woman, & child!
Minerals must be mined from the Earth.
they are nonrenewable resources, so once we use them up, we will have no more to use.

5. There are over 3000 minerals.
Every mineral is different b/c it’s made of different atoms.
The harder it’s to find or get out of the Earth, the more expensive it will be.

6. Some pure elements make up minerals. Example: gold, platinum.
Minerals form everywhere.

7. How minerals form
as magma cools crystals grow (Through crystallization of melted materials)
As water evaporates or cools leaving minerals behind (Through crystallization of materials dissolved in water)
Generally happens slowly

8. To be a mineral, something must be……

9. naturally occurring

10. inorganic
It did not come from a living or once living thing

11. solid NO
Yes NO

12. Have a crystalline structure
Symmetrical arrangement of atoms
Atoms determine structure which determines all properties about the mineral.

13. Crystalline NOT Crystalline

14. Mineral Properties
Each mineral has its own unique properties. They are used to identify the mineral.

15. Color-not the best because minerals can come in more than 1 color

16. Luster-ability to reflect light-
metallic
nonmetallic

17. Density
A measurement of how tightly packed the atoms are.

18. Cleavage OR Fracture-
ability to be split along a flat surface (weaknesses in bonds)
when they don’t break apart easily.

19. Crystal systems-
crystal shape, outer appearance, forms as crystal grows atom by atom.

20. Hardness
A measurement of how much a mineral resist being scratched

21. Streak
The color of a minerals powder

22. Special Properties Fluorescence Magnetism Radioactivity Reactivity
Conduct electricity
