Igneous Rock formation
Liquid Rock above the surface
What is lava?
This feature of Igneous Rocks defines how large or small the grains will be
What is texture?
This describes the process of making sediments while remaining in place
What is weathering?
The agent responsible for temperature change
What is heat?
These rocks form because of molten rock
What are Igneous Rocks?
Liquid Rock below the surface
What is magma?
This word defines Igneous Rocks that have small grain sizes due to fast cooling
What is Aphanitic?
These types of Sedimentary Rocks are made from chunks of other rocks
What are Clastic Sedimentary Rocks?
The word used to describe a change in form
What is metamorphism?
A rock that changes without melting
What is a metamorphic Rock?
Extrusive Igneous rocks form because of molten rock on the surface cooling. They are also known as this
What is volcanic?
These special types of Igneous Rocks have incredibly large grains (>3cm)
What are Pegmatitic?
This type of Sedimentary Rock may contain fossils
What is an organic Sedimentary Rock?
When pressure is applied to rocks this quality of the rock increases
What is density?
These are the processes by which rocks become Igneous Rocks
What is Melting and Cooling?
Intrusive Igneous rocks are formed from molten rock below the surface and are also known as this
What is Plutonic?
These types of Igneous Rocks have formed many air pockets within them
What are Vesicular Igneous Rocks?
In this stage of Sedimentary Rock formation, sediments are placed somewhere
What is Deposition?
This type of metamorphism has to do with larger area pressure
What is regional metamorphism?
These are the things that must be applied for Rocks to become metamorphic
What are Heat and Pressure?
This break in the earth's crust is how most igneous rocks underground are made
What is a magma intrusion?
Ultramafic Igneous Rocks contain far more of these minerals than any other (need both)
What are Iron (Fe) and Magnesium (Mg)?
This is the combined process of compaction and cementation by which sediments become a complete rock
What is Lithification?
Contact metamorphism happens because of a rock's proximity to this
What is a magma intrusion/chamber?
This is the abbreviation (or acronym) for the process of becoming sedimentary rocks
What is W.E.D.C.C./W.E.D.L.?
