Properties of Minerals
The way light reflects off of a mineral
Luster
This cools outside earth creating an igneous rock
Lava
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks
Sediments
Name the three types of rocks
Igneous, Metamorphic, Sedimentary
Process of rocks changing from one kind of rock to another kind over a long periods of time
Rock cycle
You can see this property by just looking at the mineral; many minerals can be several of these
Color
This kind of igneous rock is formed when magma cools beneath the surface
Intrusive Igneous Rock
these are two ways sediments are formed
Weather and erosion
A hard substance composed of one or more minerals
rocks
This is found in our cereal that we eat and is an essential mineral for our bodies
Iron
Another way to identify minerals; it leaves the color of the powder behind when rubbed against a rough white tile.
Streak Test
Extrusive igneous rocks cool quickly at earth's surface creating this type of crystal
Small
These two things cause metamorphic rocks to form
Heat and pressure
After weather and erosion a metamorphic rock becomes
sediments
Sandstone is deposited into layers from pieces of sand, it is this type of rock
Sedimentary
The scale that is used to measure the hardness of minerals- Provide the name
Mohs Hardness Scale
This type of igneous rock is black with a glassy texture. We looked at it in class.
Obsidian
For an igneous rock to become a sedimentary rock, what needs to happen
Weather, erosion, compact
Rock that has coarse, large-grained crystals- be specific
Hardest mineral on Earth
Diamond
When deciding between two minerals this test/number is definitive and unique to each mineral
Density
This determines the size of crystals that form in igneous rocks
Cooling Rate
Limestone contains fossils- it is this type of rock
Sedimentary
Naturally occurring inorganic solid, that has a definite chemical composition and crystal structure
Mineral
5 ways to test properties of minerals
luster, streak, hardness, color, cleavage/fracture
