Not made by humans
What is naturally occuring
100
How reliable is color for identifying a mineral, and why?
Not reliable, because the same mineral can be many different colors, and many different minerals can be the same color
100
The process in which minerals form
What is crystallization
100
How do you test for color?
Look at the mineral.
100
The amount of matter something has
What is mass
200
Not from living things
What is inorganic
200
What are two examples of luster?
Metallic (shiny) or not metallic (dull)
200
How do minerals form from cold solutions?
Water can dissolve minerals. When the water evaporates, minerals can crystallize again.
200
How do you test for luster?
Look at the mineral.
200
The amount of space something takes up
What is volume
300
Atoms are packed tightly together
What is solid
300
Why is it important to test for a mineral's streak rather than just its color?
Sometimes the streak is different than the color.
300
How do minerals form from magma?
When magma cools and hardens, new rocks form, and rocks are made of minerals
300
How do you test for streak?
Rub the mineral on a streak plate and look at the color of the powder.
300
What is the DEFINITION of density?
The amount of matter something is made of divided by the amount of space it takes up.
400
Atoms form an orderly repeating pattern
What is crystal form
400
Why are some minerals more dense than others?
Because they are made of different elements that have different masses.
400
How do minerals form from hot solutions? Where does this often occur?
Minerals can crystallize out of very hot water, often times in faults.
400
What is the difference between cleavage and fracture?
Cleavage is when the mineral breaks with smooth, flat surfaces. Fracture is when the mineral breaks with rough, uneven surfaces.
400
What is the difference between weight and mass?
Mass is the amount of matter something is made of. Weight is an object's mass multiplied by gravity.
500
All samples of a mineral are made of the same elements
What is definite chemical composition
500
What are two examples of special properties of minerals?
Magnetism, odor, reaction to acid, fluorescence
500
What are two examples of minerals that can form from hot solutions?
Gold, silver, platinum, copper
500
What are the tools you can use to test for hardness IN ORDER FROM softest to hardest?
Fingernails, pennies, nails, glass

Describe Archimedes Principle.
If you place an object in water, the amount of water that is displaced is equal to the volume of the object.
