100
define hardness
how hard is the mineral is.
100
is a diamond a mineral
yes
100
what is the color of pyrite
fools gold
100
what is the definition of streak
is a method used to determine the color of a mineral in powdered form.
100
what is the definition of cleavage
Cleavage - The tendency of a mineral to break along flat planar surfaces
200
what one of the hardness scales
mohs hardness scale
200
define luster
luster is the way light interacts with the surface of a crystal, rock, or mineral.
200
what is a advantage for color
the mineral has one color
200
what is a advantage for streak
to know what the streak is
200
define fracture
in the field of mineralogy, fracture is the texture and shape of a rock's surface formed when a mineral is fractured.
300
is coal a mineral give me the 2 mineral characteristics that kinda make it a mineral
solid and naturally occurring
300
explain what luster means
it means that raes of light reflect off a mineral
300
what is a disadvantage for color
is that there could be many minerals with a simaler color group and a advantage is it narrows down the number of minerals that it could be to a smaller amount.
300
Why is the streak plate method important?
Streak plate technique is used to grow bacteria on a growth media surface so that individual bacterial colonies are isolated and sampled.
300
does fracture break into a flat surface
no cleavage does
400
what item are used for hardness in the mohs hardness scale
finger nail,penny,and nail
400
What are the Physical properties that we use to identify minerals?
Color, Luster, Streak and cleavage fracture
400
which mineral is blue
amorphous
400
what a disadvantage for streak
don`t see a powdery streak
400
does cleavage breaks without a definite shape
no
500
what does density =
mass over volume
500
what are the characteristics of minerals
naturally occurring
inorganic
solid
definite chemical composition
crystal structure
500
is a crystal a mineral and why is or not a mineral
because it has all five characteristics
500
what color streak does pyrite have
the streak is black
500
does cleavage break into a flat surface
yes
