ASBOG PRACTICE QUIZ 2 FG PG 2026
2027 GEOLOGY QUESTIONS ANSWERS AND
DETAILED EXPLANATIONS
*A large landslide in an area underlain by clayey soils
MTBE - CORRECT ANSWERS -Methyl Tertiary Butyl Ether
Finding MTBE source in an unconfined aquifer - CORRECT
ANSWERS -GIS
,Trilobites are important to the dating of rocks b/w the Cambrian and the
Permian b/c - CORRECT ANSWERS -Their presence defines the
lower limit of the Cambrian Period and Paleozoic Era.
Generate a series of maps providing geologic features, delineating map
coverage of investigations/reports done in the area. One million acres.
What scale of maps would be appropriate for the presentation? -
CORRECT ANSWERS -Small-scale maps
In an area of limited surface outcrops, is a large overturned anticline
composed of an incompetent bed bounded by two competent beds. How
would you determine which limb is overturned? - CORRECT
ANSWERS -Examine drag folding within the incompetent bed
Drag Faults - CORRECT ANSWERS -occur in conjunction with
faults, and they represent the bending of rock before it breaks
,What would be the proper stratigraphic reference for the formally name
Kaibab limestone formation which was deposited during the end of the
Permian? - CORRECT ANSWERS -Kaibab Limestone (Late
Permian)
What happens in an oxidation-reduction reaction? - CORRECT
ANSWERS -Electrons are transferred b/w chemical species, changing
the oxidation states
Soils described as a CH would be _______ - CORRECT
ANSWERS -High plasticity clays
Geologic map 1:24000 the outcrop of a geologic unit measures 0.4"
perpendicular to strike. How many feet wide is the outcrop? -
CORRECT ANSWERS -24000/12 = 2000
, 2000 X 0.4 = 800'
Coal rank is based on the degree of metamorphism (coalification) and is
based on heat value, fixed carbon and volatile matter in the coal. With
increased rank one would expect - CORRECT ANSWERS -a higher
density and higher specific gravity
A circular feature found on a geologic map in an area of moderate relief
could result from which of the following? - CORRECT ANSWERS -
*a structural dome
*an intrusion
*a horizontal bed
What are the optimum conditions for fish in fresh water streams and lakes?
- CORRECT ANSWERS -pH range of 6.5 to 9.0
