Igneous Rocks
This can cool and harden and form igneous rock.
What is magma or lava?
These are little pieces of rocks, pebbles, mineral grains, and shell fragments that eventually form rocks.
What are sediments?
The way light reflects off of a mineral.
What is luster?
Name the three types of rock groups.
What is Sedimentary, Igneous and Metamorphic?
The process of rocks changing from one kind of rock to another kind of rock over long periods of time.
What is the rock cycle?
This kind of igneous rock is formed when magma cools beneath the Earth's surface.
What is Intrusive igneous rock?
These are two ways that sediments are formed.
What is weathering and erosion?
The scale that is used to measure the hardness of minerals
What is Moh's Hardness Scale
The Thickest layer of the Earth.
What is the Mantle?
This layer of earth includes the crust and the top portion of the mantle.
What is the lithosphere?
This type of igneous rock forms when lava cools on the Earth's surface.
What is Extrusive igneous rock?
These 2 things cause metamorphic rocks to form.
What are heat and pressure?
Another way to identify minerals; it leaves the color of the powder behind when rubbed against a rough white tile.
What is streak?
A naturally occurring, inorganic solid, that has a definite chemical composition and crystal structure.
What is a mineral?
What happens if an igneous rock weathers? What rock does it turn into?
What is sedimentary rock?
Why are diamonds formed in the mantle?
Heat and pressure from in the earth
For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, compaction, and cementation?
The property that causes one mineral to scratch another
What is harness?
A hard substance composed of one or more minerals.
What is a rock?
The hardest mineral.
What is a diamond?
This determines the size of crystals that form in igneous rocks.
What is the cooling rate of the magma or lava?
What would happen if heat and pressure is applied to a sedimentary rock?
Form a metamorphic rock
You can see this property just by looking at a mineral. Many minerals can be several of these.
What is color?
This is the source of energy to form sedimentary rock.
What is the sun?
The 5 ways to test the properties of a mineral.
What is luster, streak, hardness, color and cleavage or fracture
