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?
This texture is a unique texture to metamorphic rocks where there are light and dark stripes.
Banding
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?
What can you look for to define a sedimentary rock.
What is grains, sediments, organic materials (shell, fossil ect)?
The scale that is used to measure the hardness of minerals
What is Moh's Hardness Scale
A fossil would be found in this type of rock.
What sedimentary?
This texture is exclusive to metamorphic rocks and can be described as "layered"
What is Foliation
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?
In order to be a mineral a substance must be these 5 things.
A naturally occurring, inorganic solid, that has a definite chemical composition and crystal structure.
What happens if an igneous rock weathers? What rock does it turn into?
What is sediments / sedimentary rock?
This type of igneous rock is black with a glassy texture. We looked at it in class.
What is obsidian?
For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, compaction, and cementation?
The property that causes a mineral to glow under ultraviolet light
What is flourescent?
This rock type can have vesicular texture.
What is igneous 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?
The type of sedimentary rock that can contain fossils.
What is Bioclastic sedimentary?
You can see this property just by looking at a mineral. Many minerals can be several of these.
What is color?
Igneous rock that has fine-grained crystals
What is extrusive igneous rock?
The 5 ways to test the properties of a mineral.
What is luster, streak, hardness, color and cleavage or fracture
