100
A mineral's resistance to being scratched.
What is hardness?
100
This type of rock forms from heat and pressure.
What is metamorphic rock?
100
This type of metamorphism occur on a large scale, where mountain-building activities are happening.
What is regional metamorphism?
100
This word means "rich in magnesium and iron."
What is Mafic?
100
The amount of space a substance takes up.
What is volume?
200
All silicate minerals must contain these 2 elements.
What are silicon and oxygen?
200
These 2 processes are required to transform a rock into a type of rock that may have a foliated texture.
What are heat and pressure?
200
This type of metamorphism occurs when magma intrudes into existing rocks.
What is contact metamorphism?
200
This word means that the igneous rock has gas pockets.
What is vesicular?
200
The only liquid layer inside Earth.
What is Outer Core?
300
This mineral could have either metallic or non-metallic luster.
What is hematite?
300
This type of rock can be classified into 2 categories: intrusive or extrusive.
What is igneous rock?
300
This foliated metamorphic rock has mineral alignment and is composed of mica.
What is slate
300
This type of igneous rocks formed by fast cooling and solidification of lava on the Earth's surface.
What is extrusive (igneous) rocks?
300
The amount of matter per unit of space.
What is density?
400
This mineral can scratch amphibole, forms cleavage when broken and contains the element potassium. It is used in ceramics or glass.
What is Potassium Feldspar?
400
These 2 processes turn a sedimentary rock into an igneous rocks.
What are melting and solidification?
400
This nonfoliated metamorphic rock composed of carbon is formed from regional metamorphism.
What is anthracite coal?
400
This intrusive (plutonic) rock with coarse crystal size contains plagioclase feldspar, biotite, and amphibole.
What is Diorite?
400
The difference in elevation between two contour lines that are next to each other.
What is Contour Interval?
500
This non-silicate mineral has a non-metallic luster, it is easily scratched by a fingernail and used to make plaster or drywall.
What is selenite gypsum?
500
This substance is a naturally occurring solid that is a mixture of one or more minerals and does not necessarily have to be inorganic.
What is a rock?
500
The parent rock of this metamorphic rock is schist.
What is gneiss?
500
This extrusive igneous rock is glassy and vesicular, does not contain any potassium feldspar.
What is Scoria?
500
The difference in elevation divided by distance.
What is Contour Gradient?
