Properties of Rocks
100
Geologic forces and processes cause rocks to _________.
What is change?
100
If an igneous rock forms from lava that cools on Earth's surface, it is called this.
What is extrusive?
100
In this process, sediment is squeezed and the size of the pore space between sediment is reduced.
What is compaction?
100
The process by which heat, pressure, or chemical processes change one type of rock to another.
What is metamorphism?
100
Canadian geologist N. L. Bowen studied this.
How do minerals tend to crystallize?
200
In the rock cycle, if an igneous rock is exposed to Earth's surface, weathering and erosion cause it to turn into this.
What is sediment?
200
If an igneous rock forms from magma that cools beneath Earth's surface it is called this.
What is intrusive?
200
In this process, sediments are glued together by minerals that are deposited by water.
What is cementation?
200
When magma comes into contact with existing rock this type of metamorphism occurs.
What is contact metamorphism?
200
This flow chart created in 1928 showing simplified patterns that explain the order in which minerals form as magma solidifies is known as this.
What is Bowen's reaction series?
300
Sediment can be __________ and/or __________ to become sedimentary rock.
What is compacted and/or cemented?
300
This type of igneous rock is made from a large portion of silica. It will be light in color.
What is felsic rock?
300
These are the three classes of sedimentary rock.
What are chemical, organic, and clastic?
300
This type of metamorphism occurs over a large area during periods of high tectonic activity.
What is regional metamorphism?
300
This happens as minerals crystalize first, changing the composition of magma.
What is that they remove certain elements from the magma?
400
These conditions cause rocks to change into metamorphic rock.
What is high temperature and pressure?
400
Mafic rock is rich in these two elements and is low in silica. It is darker in color.
What is iron and magnesium?
400
This class of rocks forms when ions from dissolved minerals precipitate out of water because of changing concentrations of chemicals.
What is chemical sedimentary rock?
400
This occurs in some metamorphic rock textures when minerals are arranged in planes or bands.
What is foliation?
400
These igneous rocks, which are lower in silica, crystallize at high temperatures and therefore crystallize fist.
What are mafic igneous rocks?
500
If a rock melts and forms magma, it will turn into this type of rock.
What is an igneous rock?
500
Granite is considered coarse-grained. It is therefore a ___________ rock.
What is intrusive?
500
This class of sedimentary rock forms when rock fragments get carried away from their source by water, wind or ice and are left as deposits.
What is clastic sedimentary rock?
500
Marble has this texture of metamorphic rock.
What is nonfoliated?
500
Quartz crystallizes at a _______ temperature.
What is low?
