Igneous Rocks
This can cool and harden and form igneous rocks
Magma or lava
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks
Sediments
The way light reflects off of a mineral
Luster
Name the three types of rocks
Sedimentary, igneous, metamorphic
Process of rocks changing from one kind of rock to another kind over a long periods of time
Rock cycle
This kind of igneous rock is formed when magma cools beneath the surface
Intrusive Igneous Rock
these are two ways sediments are formed
You can see this property by just looking at the mineral; many minerals can be several of these
color
A fossil is___
Imprint of an organism on a rock
Two ways people use minerals
Toothpaste tubes, roads, jewelry, etc
This type of igneous rock forms when lava cools on the earths surface
Extrusive igneous
These two things cause metamorphic rocks to form
Heat and pressure
Another way to identify minerals; it leaves the color of the powder behind when rubbed against a rough white tile.
Streak test
Naturally occurring inorganic solid, that has a definite chemical composition and crystal structure
Mineral
What happens if an igneous rock weathers? What rock does it turn into?
Sediments are made to sedimentary rock
This type of igneous rock is black with a glassy texture.
Obsidian
For an igneous rock to become a sedimentary rock, what needs to happen?
Weather, erosion, compaction, and cementation
Property that causes mineral to glow under UV light
Fluorescent
A hard substance composed of one or more minerals
Rock
Hardest mineral
Diamond
This determines the size of crystals that form in igneous rocks
This type of sedimentary rock can contain fossils
Organic sedimentary rocks (limestone)
The scale that is used to measure the hardness of minerals
Mohs hardness scale
Igneous rock that has fine-grained crystals
Extrusive igneous
5 Ways to test properties of a mineral
Luster, streak, hardness, color, cleavage/fracture
