Anything we use from nature
What are the 5 characteristics minerals have in common?
Solid, usually inorganic, naturally occurring, definite Chemical composition, crystalline structure
What are the 6 way we identify minerals?
Color, Streak, Density, Cleavage/Fracture, Hardness, Luster
What is a renewable resource?
A resource that comes back as quickly as we use it
Describe what it means for a mineral to be naturally occurring.
They are made from the Earths processes
Color is the visible, streak is the color of the powdered form of a mineral.

Describe luster
How the surface of a mineral reflects light
Describe what a fossil fuel is
formed from the buried remains of plants and animals. It is a type of nonrenewable resource.
Describe what it means for a mineral to have a definite Chemical composition.
They are made up of the same materials throughout.
Describe Hardness. What is the name of the scale used to measure hardness?
Hardness is the resistance to being scratch.
Moh's Hardness Scale
What does it mean if a resource is inexhaustible? Give an example
We will never run out of that resource. Solor or wind energy
Minerals have a repeating pattern of crystals they are formed by.
Describe Cleavage AND Fracture
Cleavage - smooth, even, clean breaks
Fracture - uneven, rough, jagged breaks
