1.Naturally occurring
2.Inorganic
3.Solids with specific compositions
4. Definite crystalline structuresColumn 1, 100
What are characteristics of
minerals
Column 1, 100
A diamond mineral has a mass of 75g and a volume of
25 cm3.
Calculate the density of the diamond.
Column 1, 200
Density= Mass/Volume = 3.0 g/cm3.
Be sure you can calculate the mass when given the density.
Mass= Density x VolumeColumn 1, 100
1. Crystal form
2. Luster
3. Hardness
4. Cleavage and fracture
5. Streak
6. ColorColumn 1, 300
What tests used to identify minerals
Column 1, 300
1. Oxygen, O
2. Silicon, Si
3. Aluminum, Al
4. Iron, Fe
5. Calcium, Ca
6. Sulfur, S
7. Potassium, K
8. Magnesium, MgColumn 1, 400
What are the rock forming minerals or the most abundant minerals found in
Earth’s crustColumn 1, 300
A mineral that contains a valuable
substance that can be mined at a profit
Column1, 500
What is an ore?
Column 1, 300
1.Temperature
2. Pressure
3.Water Content
4.Mineral Content
Column 2, 100
What are the 4 main factors involved in
MAGMA formation
Column 1, 300
Both ___________, measured in °C, and _______, measured
in MPa, increase with depth.
Column 2, 200
What is temperature and pressure.
Column 1, 300
This Canadian geologist demonstrated that as magma
cools and crystallizes, minerals form in predictable patterns.
Column 2, 300
Who is N.L. Bowen? (Process is now known as the
Bowen’s Reaction series.)
Column 1, 300
1.Mineral composition
2.Crystal size
3.Texture
Column 2, 400
What are 3 ways to classify igneous
rocks?
Column 1, 300
When ________ cools rapidly, there is not
enough time for large crystals to form resulting
in _______ rocks.Column 2, 500
What is magma, and extrusive rocks
** What are intrusive rocks???***
Column 1, 300
Lithification begins with ________, (see figure 6.4, page 137).
Column 3, 100
What is compaction?
*** What is cementation? Pg
137**Column 1, 300
_______ is the primary feature of sedimentary rocks.
Two types are _____ and ________.Column 3, 200
What is bedding. Two types are :
Graded- particles heavy on bottom
Cross- inclined layers of sediment deposited across a horizontal surface
Column 1, 300
Column 3, 300
The most common sedimentary rocks are
______. These rocks may be _____, ________, or
_____ grained.
What are clastic rocks? Coarse, medium and fine grained? Be sure you know the differences
between the 3 grain types
Column 1, 300
Metamorphic rocks form when preexisting rocks are exposed to
increases in temperature and pressure and to hydrothermal
solutions. Name and describe the 3
types of metamorphism.
YOU MUST HAVE ALL 3!Column 3, 400
Regional metamorphism: high temp and pressure affect large regions of Earth’s
crust
Contact metamorphism: when molten material such as that in an igneous
intrusion comes in contact with solid rock.
Hydrothermal metamorphism: when very HOT water reacts with rock and alters its
chemical and mineral composition
Column 1, 300
This rock type may be in your bathroom or home.
It results from the metamorphism of this
rock type.Column 3, 500
Marble; what is limestone?
Column 1, 300
List the units of geologic time from longest to shortest.
Column 4, 100
Eons, eras, periods, epochs
Column 1, 300
Scientists date rocks using these 2
methods.
Column 4, 200
What are relative age dating and absolute
age dating?
Be sure you know how each
method is used.Column 4, 200
Sometimes, the record of a past event or time period are missing.
These erosion gaps result in:
Column 4, 300
What are unconformities? Pg
598
Column 4, 300
Fossils with ______ ______ have been altered very little, such as Fig 21.21, pg 607.
These are different from _____ fossils, which leave indirect
evidence only.Column 4, 300
What is original preservation and
trace fossils?
Column 5, 100
In this era, mass extinction resulted in 90% of marine animals becoming extinct.
Column 4, 300
What is the Paleozoic era?
** What is significant about the Phanerozoic eon, pg. 592 (There
may be a daily double!!!) Column 5, 200
Rivers that flow into other streams are
called:_______ Examples include the Ohio and Miss
rivers.Column 4, 300
What are tributaries
Column 5, 300
Calculate the discharge of a stream with an average width of 4m, and average
depth of 2.5m, and average velocity of 2 m/s.
Column 4, 300
Discharge=
average width x average depth x average velocity
4m x 2.5 m x 2 m/s = 20 m3/s
Daily double! Calculate the velocity if the discharge of this
stream = 20000 m3/sColumn 5, 400
During this process, a stream actively resumes
the process of downcutting toward its
base level. Column 4, 300
What is rejuvenation
READ pg 237! Column 5, 500
According to page 238, most lakes in North America are formed in this way.
Column 4, 300
What is by glaciers that carve depressions in the
Earth
Column 4, 300
T or F? Wetlands result from the process by
which the surrounding watershed enriches bodies of water with nutrients , a
process called:_______ Column 4, 300
Eutrophication, True
