Where are Intrusive Igneous Rocks formed?
Igneous Rocks are formed inside the Earth.
100
What three things could be found in Sedimentary Rocks?
Three things are weathered rocks, plants, and/or animal remains.
100
How do Metamorphic Rocks form?
Metamorphic Rocks are formed through heat, pressure, and chemical reactions.
100
Are minerals man-made or naturally occurring?
Naturally occurring!

What does the word Igneous mean in Latin?
Igneous means "fire-formed".
200
What are the horizontal layers found in Sedimentary Rock called?
The layers are called "beds".
200
What do Foliated Metamorphic rocks have that Non-foliated do not?
Bands of minerals.
200
What is the name of the test geologists perform to see the color of the mineral's powder?
The Streak Test!
300
What is the only type of rock in which fossils are found?
Sedimentary
300
What would an Igneous rock that is dark in color be called?
An Igneous rock that is dark in color is called "mafic".
300
How are Sedimentary Rocks formed?
Sediments are compacted and cemented together.
300
When does "Regional Metamorphism" occur?
When mountains are being built.
300
What is the name of the scale used when conducting the hardness test?
Moh's Hardness Scale
400
What is the name given to scientists who study the Earth's rocks and minerals?
Geologists
400
What are the two types of grains an Igneous rock could have?
The two types are fine-grained and coarse-grained.
400
How are Clastic Sedimentary Rocks made differently than Chemical Sedimentary Rocks?
Clastic rocks are made of sediments cemented together. Chemical rocks are left behind when the solution they were in evaporates.
400
What is the most important element in Hydrothermal Metamorphism?
Water

What do geologists mean by "cleavage"?
How a mineral breaks.
500
How many phases are in the rock cycle, and what are their names in order?
Three; Igneous - Sedimentary - Metamorphic
500
Why are some Igneous rocks "glassy"?
They froze instantly when being formed.
500
What makes up Organic Sedimentary rocks?
Once-living organisms and plants make up the Organic family.
500
In Contact Metamorphism, what is the thing that causes the rocks to change into something new?
Magma
