LSU GEOL 1001 EXAM 2 COMPLETE STUDY
GUIDE WITH SOLVED QUESTIONS
◉ Which of the following changes in conditions would cause melting
of a solid rock?
Answer: from A to B
◉ Which of the following is a correctly described part of the
hydrologic cycle?
Answer: most groundwater forms when water on the surface
infiltrates into the ground
◉ Which area(s) on this world map are likely to be near a plate
boundary?
Answer: A, B, and C only
◉ How did an oxygen-rich atmosphere develop from a carbon
dioxide-rich atmosphere?
Answer: Through photosynthesis by cyanobacteria
◉ An ophiolite is identical to:
Answer: a newly formed segment of oceanic crust, except it contains
an additional layer of sediment
,◉ In accordance with the pressure gradient
Answer: air is more tightly packed in high pressure zones and moves
away from low pressure zones.
◉ Which of the following statements correctly states how early
crystallization affects the composition of a magma? Use the graph.
Answer: Early crystallization causes the MgO (mafic) content to
decline in the magma.
◉ In which areas on the accompanying figure is condensation
occurring?
Answer: 2 and 3
◉ Which of the following is characteristic of continental rifts?
Answer: all of these
◉ Which of the following cannot be caused by overpumping of
ground water?
Answer: all of these are possible consequences of overpumping
◉ Which of the following is the best example of heat transfer by
conduction?
, Answer: a pan is placed directly on a burner
◉ The Coriolis effect in this figure shows the deflection of cold air as
it rushes in to replace hot rising air above a low pressure zone. The
Coriolis effect:
Answer: requires a very large air masses since it requires defection
by the Earth's rotation
◉ This cross section shows the location of 5 wells and the water
table? Which well is most likely to be an artesian well?
Answer: well E
◉ Which of the following collection of fossils would be LEAST useful
for determining the age of a section of rocks?
Answer: the fossil of a family of creatures that lived unchanged for a
very long time
◉ Using the data in this table, calculate the number of half-lives that
have passed for the granite (unit G on this table)?
Answer: 3
◉ On this southern continent, which side has a plate boundary?
Answer: the left (west) side
