1. Intro to the GEOLOGY unit!
Minerals
Rocks
Rock cycle

2. Erosion
Fossils
Relative dating

3. Earthquakes
Volcanoes

4. Minerals – Can you SNIFC it?
Definition: a naturally occuring, inorganic solid, with a crystalline structure and definite chemical composition
Mineral must be:
Solid
Naturally occuring
Inorganic
Formula or Definite chemical composition
Crystalline structure

5. Solid
Cannot be deformed (change shape) or change volume
???

6. Naturally Occurring
Cannot be manmade

7. Inorganic INORGANIC: ORGANIC: Consist of non-living material
Consist of living or once living material
Coal—made by carbon atoms from ancient trees—trees are living—not a mineral--organic
Gold—made by gold atoms—mineral--inorganic

8. Organic? OR
inorganic?
ORGANIC VEGTABLES

9. Formula or Definite chemical composition
Any given mineral always has the same chemical composition. We say it has a specific formula. Chemical formulas are a way to describe the specific types and amounts of atoms in a substance.
Example:
Mineral gold: chemical composition Au (gold)
Mineral Diamond: chemical composition C (carbon)
Mineral halite: chemical composition NaCl (sodium and chlorine)
Mineral quartz: chemical composition SiO2 (one Silicon and 2 Oxygen)
