7. These are Minerals.

8. What are Minerals?
Cornell Notes Page 129

9. ATOMS = BUILDING BLOCKS of everything in the Universe.
What are atoms?
ATOMS = BUILDING BLOCKS of everything in the Universe.

10. What is an element?
A substance that cannot be broken down into simpler things.
Examples: Gold, silver, aluminum

11. What is a compound? A substance made of more than one element
Examples: Water, table salt

12. MINERALS 3,000 + different kinds of minerals
Most are made of combinations of elements (compounds)

13. 5 Characteristics of Minerals
1. Naturally occurring
2. Inorganic
=not from a living thing

14. 45 seconds to Discuss… What does it mean to be “naturally occurring?”
What does it mean to be “inorganic?”

15. 4. Crystal Structure –particles line up in a pattern
3. Solid
4. Crystal Structure –particles line up in a pattern
Pyrite in rock

16. 45 seconds to Discuss… What does it mean to be “solid?”
What does it mean to have a “crystal structure?”

17. Examples of solid, crystal structure
Rhodochrosite

18. 5. Definite Chemical Composition
A mineral…
5. Definite Chemical Composition
Ex.) Water = H2O
Salt = NaCl

19. An example of: definite chemical composition
Calcite—has the chemical name--CaCO3
An example of: definite chemical composition
Ca=Calcium (as in your bones)
C=Carbon (in all living things)
O= Oxygen (in the air)

20. 60 seconds to Discuss… What do we mean by “chemical composition?”
So then what does it mean to have a “definite chemical composition?”

21. What are the two groups of Minerals?
Silicate Minerals
chemical composition with a combination of Silicon and Oxygen
Quartz = SiO2

22. Nonsilicate Minerals
Do NOT contain a combination of silicon and oxygen.
 Fluorite = CaF2

23. 45 seconds to Discuss…
How are Silicate Minerals and Nonsilicate Minerals different?

24. How do Minerals form? In Magma and Lava
Minerals crystallize in the liquid rock.
Different Minerals begin forming crystals at different temperatures- this causes them to separate out into pure samples.

25. How do Minerals form? In Magma and Lava
If magma cools quickly, crystals don’t have time to grow.
The slower the magma cools, the bigger the crystal can grow!

26. In Water
Elements and compounds dissolved in water crystallize as the water evaporates

27. What’s in these minerals/rocks that look so delicious?
Oxygen
Silicon
Aluminum
Magnesium
Iron
Sodium
Calcium
Potassium

28. The result of eating rocks and minerals…
