Question 1
You have an outcrop of sandstone that contains inclusions of a limestone. What does that tell you about the age of the sandstone versus the limestone?
the sandstone is older
the limestone is Paleozoic because its inclusions contain fossils
the limestone and the sandstone are the same age
the limestone is older
Question 2
What is the difference between relative and absolute age dating?
Relative dating involves your sister or brother, absolute age dating involves a committed relationship, no matter with whom
relative age dating involves putting a real age number on an event, absolute age dating involves telling which came first and which came second
relative age dating involves telling which came first and which came second, absolute age dating involves putting a real (absolute) age number on an event
they are both the same thing
Question 3
The first abundant metazoan fossils appear at the beginning of the _____________?
Proterozoic
Cambrian
Permian
Cretaceous
Question 4
The Principle of Inclusions states that ___________________?
rocks that contain inclusions of another rock are always younger than the rock from which the inclusions came
rocks that contain inclusions of another rock are always older than the rock from which the inclusions came
inclusions are always darker colored than the rock that contains them because they are older
inclusions always contain fossils that will tell you the relative age of the rock
Question 5
______________ occurs when there are missing deposits between 2 flat-lying formations. This is the most difficult type of unconformity to detect.
rounded unconformity
nonconformity
disconformity
angular unconformity
Question 6
The word PALEOZOIC means ________? all life
early life
recent life
middle life
Question 7
Which type of unconformity has metamorphic or igneous rocks in contact with sedimentary rocks
disconformity
nonconformity
angular unconformity
flat unconformity
Question 8
The Principle of Original Horizontality states that _________?
igneous rocks are always deposited horizontally
metamorphic rocks are always deposited horizontally
all rocks are horizontal
sediments or lava flows are generally deposited horizontally
Question 9
What is the Principle of Superposition?
Geologic structure is younger than any geologic structure it cuts across.
in an undeformed sequence of sedimentary rocks, the oldest rocks are on the top
in an undeformed sequence of sedimentary rocks, the oldest rocks are on the bottom
older rock fragments found within igneous intrusions.
it is “super” to be in the top position
Question 10
An INDEX FOSSIL must be _______________________?
geographically widespread
easy to identify
limited to a short span of geologic time
all of the answers shown
Question 11
Earthflows are most common in ____________?
humid regions
dry regions
areas underlain by granite
areas with no hills or mountains
Question 12
Which of the statements is NOT true about Rock Fall ?
Rock fragments break off from steep bedrock slope.
Rock falls with a slow speed in a rock fall mass wasting.
Most common cause of Rock Fall, or breaking off of rock material is frost wedging.
Rock fall happens at vertical or near vertcal angles.
Question 13
In mass wasting an outside force that gets things moving is called a trigger. One of the most common triggers is the vibrations of an earthquake. What are the two important processes through which an earthquake can trigger a mass wasting event.
[please choose two answers]
Earthquake vibrations can sepprate weak spots in rocks, and break the cohesion between rock and soil particles.
Earthquakes cause fire and that makes the trees dead and this triggers a mass wasting event.
Earthquakes raise the temprature and this causes metlting which reduces friction and this leads to mass wasting.
Earthquakes trigger liquifaction in some soil which casues them to loose cohesion.
Question 14
Which of the following is NOT used to classify mass wasting events?
type of material involved
type of motion of the material
speed (velocity) of the event
hardness of the material
Question 15
The angle of repose for dry sand is
10 degrees.
25 degrees.
45 degrees.
65 degrees.
Question 16
In geologic terms, CREEP is _______________?
what a baby does before he learns to crawl faster
what a car driven by a timid person might do
very slow movement of soil downhill
rapid movement of soil and regolith after an earthquake
Question 17
The tendency for like particles to stick together is called
strength.
cohesion.
inertia.
friction.
Question 18
Which of the following forms of weathering does NOT involve a mechanical weathering process?
oxidation
frost wedging
unloading
biological activity
abrasion
Question 19
______________ is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth’s crust, then transport it away to another location
Erosion
Corrosion
Explosion
Identification
Question 20
What type of soils do we have here in the Midland/Odessa area?
alfisols
histosols
aridosols
oxisols
Question 21
Which of the following chemical weathering process alters the feldspar to clay minerals?
oxidation
hydrolysis
abrasion
dissolution
Question 22
Which SILICATE mineral is THE MOST resistant to weathering (weathers last or is hardest to weather)?
quartz
olivine
augite
biotite
Question 23
OXIDATION is a type of chemical weathering that particularly attacks what type of minerals?
quartz
carbonate minerals
evaporite minerals
iron rich minerals
