Tree/mushroom

2. Atoms-----Molecules------Minerals-----Rocks
5 Characteristics of a Mineral
Naturally occurring: not plastic, not cement
Inorganic: not from living plants or animals
Solid
Crystal structure:
Definite Chemical Composition: SiO4=silicon

3. Examples of common minerals:
Halite: salt
Quartz
Magnetite
Pyrite
Mica
Copper

4. Three Types of Rocks E D C Igneous: “Fire” from the volcano
Extrusive: small crystals
Obsidian
pumice
Igneous: “Fire” from the volcano
Sedimentary:
Metamorphic: changed by heat and pressure: swirly lines (marble, slate, gneiss)
Intrusive: large crystals
granite E D C

5. The Rock Cycle: how rocks are “reincarnated”
Erosion
Deposit
Compact
Cement
Heat and pressure

6. How soil is made by weathering:
Minerals are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
Other components of soil are from decomposition of dead plants and animals.

7. Relative Ages of Rocks: oldest on the bottom

8. How are fossils formed?

9. Earthquakes and Volcanoes:
Seismic waves transfer MECHANICAL energy, flowing magma transfers HEAT (Thermal) and MECHANICAL energy.
Faults are places in the earth’s crust where energy builds up as Potential (ELASTIC) energy. When the rocks finally release this potential energy, there is an earthquake.
The seismic waves are energy that move outward in all directions from the epicenter, gradually decreasing in energy as they travel outward.

10. P-Waves: Primary waves, first to arrive after an earthquake

11. S-Waves: Secondary, arrive next after an earthquake

12. Seismogram from a Seismograph

13. Phase Change Diagram D E C B A

14. Chemical Properties:
The ability or Potential for it to change into something new.
Cannot be reversed
Examples: flammability, oxidation (rusting), corrosive, explosive, toxic

15. Physical Property
A characteristic of matter that you can observe and measure without changing the identity
Identify with physical senses
See
Touch
Taste
Smell
Examples:
phase of matter, color, size, mass, density, freezing point, boiling point

16. Chemical Changes: cannot be reversedP G T

17. Physical Changes: Can be reversed
Melting and freezing
Chopping it up
Mixing it
Dissolving it in water
