Rocks formed from the crystallization of magma are called this.
What are igneous rocks?
100
The last mineral to form on the Bowen's Reaction Series.
What is quartz?
100
Minerals have ___________________, which is why some rocks contain more of one type of a mineral versus another. This key factor also determines the amount of each type of mineral in the rocks as they heat or cool.
What is different melting points?
100
The size, shape and distribution of crystals or grains that make up a rock.
What is texture?
100
Magma that flows onto the Earth's surface.
What is lava?
200
Igneous rocks that cools slowly and are formed within the Earth's crust.
What are intrusive rocks?
200
The two main patterns of crystallization found on Bowen's Reaction Series.
What is continuous and discontinous?
200
Light Colored rocks that have HIGH silica content, contain quartz and feldspars.
What are granitic rocks?
200
A vein of extremely large-grained minerals in rock.
What are pegmatites?
200
Molten rock found below the Earth's surface. It is fluid and moves.
What is magma?
300
Rocks that cool fast and on the outside of the Earth's Crust.
What are extrusive rocks?
300
This illustrates the relationship between cooling magma and mineral formation.
What is Bowen's reaction series?
300
A rock that have VERY little silica content and is EXTREMELY high in iron and magnesium content.
What is ultramafic?
300
The _______________ grains of igneous rocks make them strong.
What is interlocking?
300
The term that describes that the properties of magma can change as it cools or heats, therefore carrying more or less minerals within it's soupy mix.
What is fractional crystallization?
400
Extrusive rocks that cool more rapidly than intrusive rocks, are generally more of what type of texture?
What is fine grained?
400
The left branch of Bowen's Reaction Series is shows how much _______________ is in the rock as the magma cools.
What is iron?
400
These types of rocks are dark, have low silica content and high iron and magnesium content.

400
The process that forms Obsidian.
What is very fast cooling?
500
The process where some minerals melt at low temperatures while other minerals remain solid.
