Chapter 14 APES
According to the graph
As we recycle, reuse and reduce our consumption rates, we slow down depletion time of nonrenewable resources (E)
Environmentalists oppose the mining of antarctic mineral resources because
the antarctic environment is fragile and extremely vulnerable to the disturbances that would accompany development
At which of the following sites does seafloor spreading result in rifts and possible volcanoes?
A (area from which plate 2 moves away from)
The intraplate location where hot-spot volcanism is occurring
A (hawaii)
A cost-benefit analysis done to investigate a proposed mine site would likely take which of the following into account?
1, 2 and 3
Which of the following is an environmental problem associated with abandoned coal mines?
Acid drainage due to leaching of spoil heaps by rainwater
Area where new crust is being created at a divergent plate boundary
B (area east of United States)
At which of the following sites would activity result in volcanoes, island arcs, and mountains?
B (area where plate 2 is going towards)
Tectonic plates move slowly across the asthenosphere on
Convention currents (D)
Gold is obtained from areas containing low concentrations through the process of
Cyanide leeching of crushed rock (D)
The North American and Eurasian plates are moving apart from one another and creating the Mid-Atlantic ridge. This is an example of what type of plate boundary?
Divergent (B)
The location where one tectonic plate is being forced beneath another, creating a volcanic arc.
E (Area east of china)
Area that exhibits island arcs
E (area near Australia)
Forms when magma cools and hardens
Igneous (B)
Forms when pre-existing rock is subjected to high temperatures, pressure or chemicals
Metamorphic (C)
Forms when existing rock is weathered and deposited as small grains
Sandstone (D)
When a mineral resource is too deep to be surface mined, a technique known as this is used:
Subsurface mining (B)
This element in pyrite contributes to acid mine drainage.
Sulfur
Which of the following best describes the process known as "mountaintop removal"?
The use of heavy equipment to move overburden downhill during the strip mining of coal
Which of the following is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems?
There is not a gaseous phase of the phosphorus cycle, and therefore the movement of phosphorus into oceanic reservoirs is very slow.
Strip mining is a useful and economic way to extract mineral resources. However, strip mining has all of the following harmful environmental effects EXCEPT
Vegetation often flourishes (A)
One big environmental problem with smelting is
air pollution (C)
Finding substitutes for mineral resources will
help to keep supplies of resources sustainable (C)
When a mineral resource becomes scarce its
price rises (A)
