Igneous Rocks
These rocks form from cooled magma or lava
What are igneous rocks?
Small, solid pieces of rock or organic material are called this.
What is sediment?
These rocks form under heat and pressure.
What are metamorphic rocks?
The continuous process that changes rocks from one type to another.
What is the rock cycle?
A naturally occurring substance with a definite chemical composition.
What is a mineral?
Igneous rocks formed on Earth’s surface are called this.
What are extrusive rocks?
The process where wind and water move sediment away from its source.
What is erosion?
When mineral grains are arranged randomly.
What is non-foliated?
Lava cooling on Earth’s surface becomes this type of rock.
What is extrusive igneous rock?
Rocks are made of one or more of these.
What are minerals?
Igneous rocks formed beneath Earth’s surface are called this.
What are intrusive rocks?
The process that presses sediment layers together.
What is compaction?
When mineral grains are arranged in bands or layers.
What is foliated?
Sediments become sedimentary rocks through these two processes.
What are compaction and cementation?
Quartz and feldspar are examples of this.
What are minerals?
Small, hard-to-see crystals indicate this type of igneous rock.
What is extrusive?
The process in which dissolved minerals crystallize and glue sediments together.
What is cementation?
Any rock can become metamorphic through these two forces.
What are heat and pressure?
Heat and pressure deep underground can change sedimentary rock into this.
What is metamorphic rock?
Granite and sandstone are examples of this.
What are rocks?
These rocks have large, interlocking crystals.
What are intrusive rocks?
Sedimentary rocks often form in this type of environment.
What is water (or riverbeds/oceans)?
This process can turn shale into slate.
What is metamorphism?
Melting metamorphic rock would eventually form this.
What is igneous rock?
This is the main difference between a rock and a mineral.
What is that rocks are mixtures, while minerals have a specific composition.
