What is a Mineral?
-naturally occurring
-inorganic
-solid
-with definite chemical composition
-definite molecular structure
All found on the last page
of the ESRT

3. What are some mineral characteristics?
Color: Least relaible. Many minerals share the same color & the same mineral may have different colors
Streak: color of mineral in powdered form. Determined by streaking It on a white plate.
Luster: the way light reflects off it; metallic shine.
Hardness: Determined by scratching it on glass and seeing which is Harder.
Cleavage/Fracture: tendency for minerals to split. If not predictable or even ;fracture.

4. Rocks formed from the cooling of
What are igneous Rocks?
Rocks formed from the cooling of
molten materials.
Lava: above ground
Magma: Below ground.
Chart is Found on Page 6
of the ESRT

6. Types of Igneous Rocks Felsic:Low density, light color,
Composition AL & Quartz
Mafic: High Density, Dark color,
Composition Fe, Mg & Pyroxene
Intrusive: larger crystals, cooled
Slowly
Extrusive: small/no crystals,
Glasslike, gasholes. Cooled Quickly

7. What are sedimentary Rocks?
Rocks made up of other sediments.
Features of these Rocks:
Smaller sediments cemented together
Fossils
Layers

8. How do we classify Sedimentary Rocks?
Using Page 7 in the ESRT
Clastic: land derived; further classified
According to grain size. Formed from
Compaction & Compression.
Non-Clastic- these further break into:
Crystallines: Formed from evaporation of
Water & precipation of the mineral.
These look like crystals
Bioclastics- made from fossils

10. What are Metamorphic Rocks?
Using Page 7 in the ESRT
These rocks formed through extreme
heat &/or pressure & formed from other rocks.
There features are:
More dense
More resistant
Foliated
Have bands

12. What is the Rock Cycle? The rock cycle explains how rocks go
through all sorts of changes and are
constantly being recycled.
