Transcript of Bring Me The Mineral

Classifying if it's a mineral or not
Luster
Friedrich Mohs was an Austrian geologist who developed the Mohs Hardness scale in 1822. The Mohs Hardness scale ranked minerals on their resistance to being scratched with six different items. A fingernail, copper penny, steel nail, glass plate, streak plate, and a diamond.
The Difference Between a Rock and Mineral
Formation of Minerals
Magma and lava cools
Evaporation of a liquid
Hot underground water
Defining a Mineral
Solid-minerals are solid/ stable in their natural state
Naturally Occuring-created naturally through Earth's processes
Inorganic-not alive, never have been alive
Crystal structure-
Definite Chemical Composition- complex structure of atoms that makes the mineral unique
Definition
n. the building blocks of rocks
Bring Me The Mineral
A mineral is a naturally occurring, inorganic, solid at room temperature with a definite chemical composition and a crystal structure formed by geological processes. Whereas a rock may include organic remains, some rocks may not have a definite chemical composition, and a crystal structure.

Period #3
Extra: magma takes longer to cool so bigger crystals form, unlike lava.
Mineral or Nah?
Streak
Hardness
- the way light interacts with the surface of the crystal
Metallic
Vitreous
Pearly
Dull
Adamantine
- Color of a mineral in it's powdered form
- Resistance to being scratched (scratchability)
How To Test:
Luster: examine the way the mineral is defined
Streak: scrape the mineral a few times on a streak plate, and record the color of the mineral in powdered form
Hardness: scrape the mineral with the objects by going in order through the Fredrick Mohs Hardness Scale
