naturally occuring
|
Made by earthmineral- silver, diamond, sulfernon-mineral- brick, glass, coal
|
|
| 4 |
inorganic
|
made of non-living materials- never had cells

| 5 |
specific chemical composition
|
the elements that make the minerals have a definite chemical formula
|
|
| 6 |
crystal structure

color
|
the color, not always a big factor

the way a mineral shines or reflects light;mettalic, glassy, dull, waxy/pearly, greasy/talc
|
|
| 12 |
hardness
|
whether the mineral scratches things, or is scratched. measured on mohs hardness scale
|
|

What are the 2 ways a mineral breaks?
|
fracture or cleavage
|
|
| 14 |
cleavage
