Defining a Mineral
100
What property is the least reliable for mineral identification?
What is Color.
100
What does it mean if a mineral is "inorganic"?
It means "non-living" or "dead."
100
A mineral is made of rocks.
What is FALSE.
Minerals are made naturally on Earth. Rocks are made up of minerals.
100
A mineral must be this phase of matter.
Solid
200
Is the color of the mineral it it's original form always the same as the color of it's powdered form when you test it's streak?
No, the streak can be a different color on the tile from it's original color.
Example: Hemtatite
200
Ice is a mineral but water is not. Why is water not a mineral?
Liquid. Needs to be a solid (one of the 5 characteristics of a mineral).
200
An atom is made up of at least more than one molecule
What is FALSE.
Molecules are made up of more than one atom.
200
A mineral must be _______ occurring
Naturally
300
Name two different descriptions of a non-metallic luster.
glassy, earthy & dull.
300
The two ways a crystal can form
What is the cooling of magma and what is evaporation of a mineral solution.
300
Quartz can scratch Diamond.
What is FALSE.
Diamond is the toughest mineral. Only diamond can scratch diamond.
300
What does it mean to have an "ordered" internal structure?
The atoms of minerals have a crystalline or shaped lattice/pattern
400
Using the image:
Volume on the left is 20.0 mL & on the right is 22.8 mL. What is the volume of the object?
Volume on the left is 20.0 mL & on the right is 22.8 mL. What is the volume of the object?
What is 2.8 mL
400
Is coal a mineral?
No because it is organic. It is made from the remains of vegetation.
400
The two samples of the mineral pyrite have different densities.
What is FALSE.
Minerals of the same type have the same density no matter what the size.
Minerals of the same type have the same density no matter what the size.
400
What does it mean to have a "definite chemical composition?"
the mineral is made of specific elements/compounds.
500
Using Moh's Scale of Hardness:
which minerals can scratch a steel file but can be scratched by window glass?
which minerals can scratch a steel file but can be scratched by window glass?
What is Quartz and Orthoclase.
500
Even though graphite (pencil lead) and diamond come from the same atom, Carbon, their physical characteristics are completely different. Why is this the case?
Their atoms are arranged in different crystal structures.
500
The most likely way for a crystal to form is by boiling.
What is FALSE.
Evaporation results in crystal formation in a solution and cooling for crystal formation in magma/lava.
Evaporation results in crystal formation in a solution and cooling for crystal formation in magma/lava.
