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)
