What is the relationship between groundwater and surface water?
Surface water percolates through the soil to form groundwater.
There is no relationship between surface and groundwater; they form independently.
Groundwater filters through the soil to form surface water.
Surface water is found in lakes directly above underground water sources.
Many areas of the world without adequate fresh water have become habitable because
rainfall patterns have changed
water management projects have diverted water to the area
icebergs have been towed in to provide fresh water
water conservation has been implemented
Which of the following represents nonpoint-source pollution?
unlined landfill

leaking oil tanker
runoff from agricultural feedlots
Most of the pollutants in the ocean come from
commercial boats and personal watercraft.
spills from oil tankers.
activities on land.
leaking underground storage facilities.
Most large cities get water for households and industries from
deep wells.
rivers and lakes.
pumps connected to springs.
removing salt from sea water.
Which of the following might occur as a result of plastic trash accumulating in the ocean?
Turtles mistake clear plastic bags for jellyfish, ingest them, and die of intestinal blockage.
Sea birds are strangled by plastic six-pack rings.
Sea mammals, such as seals, become tangled in clear plastic fishing lines and drown.
All of the above
What pollutant forms when automobile emissions react with oxygen gas and ultraviolet rays?
ozone
radon
carbon dioxide
sulfur dioxide
All of the following are primary air pollutants except
carbon monoxide
sulfur oxides
acid rain (nitric acid)
VOC
Which of the following is often used to remove poisonous gases from industrial emissions before they are released into the atmosphere?
catalytic converters
electrostatic precipitators
crushed limestone
scrubbers
Which of the following pH measurements of rainwater would indicate acid precipitation?
pH 6.0
pH 4.1
pH 7.3
pH 9.6
Which of the following contributes most to acid precipitation?
burning of fossil fuels
ethanol
radon and ozone
All of the above
Temperature inversions work to trap pollution when
cool air above keeps warmer air at the surface from moving upward.
cool air above keeps warmer air at the surface from absorbing solar radiation.
warm air above keeps cooler air at the surface from absorbing solar radiation.
warm air above keeps cooler air at the surface from moving upward.
Which of the following activities is the largest producer of primary air pollutants in the United States?
electricity production
transportation
healthcare
agriculture
Rain frequently results whenever
cold, moist air rises.
warm, dry air sinks.
warm, moist air rises
cold, dry air sinks.
Which of the following best describes measurements of CO2 levels in the atmosphere since 1958?
Levels of CO2 were steady until the mid-1970s, when they began to increase rapidly.
Measurements of CO2 have shown a steady increase since accurate measurements began.
CO2 levels are higher in winter and lower in summer, but the winter “highs” have increased each year and the summer “lows” have not fallen as far.
CO2 levels are higher in winter and lower in summer, but the winter “highs” are higher each year and the summer “lows” are lower each year.
Latitude strongly influences climate because _____ solar energy falls on areas that are closer to the equator than to the poles.
less
the same amount of
more
sometimes less
Which of the following gases is most responsible for the greenhouse effect?
nitrous oxide
methane
oxygen
water vapor
Which of the following would occur if Earth were not tilted relative to the plane of its orbit?
Temperatures at the equator would become too hot to sustain life.
Temperate regions would no longer have seasonal changes in climate.
All parts of Earth would receive sunlight of equal concentration.
Polar ice caps would melt due to a rapid increase in global warming.
Which of the following statements related to global warming is not accurate?
Carbon dioxide levels have risen over the last 30 years.
Only fossil fuels, not living plants, release carbon dioxide when burned.
Global temperature and carbon dioxide concentration are related.
By itself, reforestation is not sufficient to slow global warming.
The difference between global warming and climate changes is that
human-made chemicals such as CFCs do not influence global warming.
previous changes in climate were dramatic but very short-lived.
climate change only occurs along the equator.
global warming is a consequence of climate changes.
Chlorofluorocarbon molecules are environmentally significant because
their chlorine atoms can destroy many stratospheric ozone molecules.
they are poisonous, flammable, and corrosive to metals.
their absorption of lethal solar energy protects Earth.
they readily break down ozone molecules produced as pollution.
The average global temperature has _____ during the 20th century.
remained the same
increased every year
risen some years and fallen others, but has increased overall
risen some years and fallen others, but has decreased overall

more ultraviolet light is able to reach Earth’s surface.
less solar energy is able to reach Earth’s surface.
the amount of methane in the atmosphere increases
the amount of phytoplankton in the ocean increases.

urbanization.
urban sprawl.
urban crisis.
infrastructure.
Which of the following statements about tree harvesting methods is correct?
Clear-cutting is quick but is more expensive than other methods due to the vast areas involved.
Selective cutting eliminates the possibility of soil erosion.
Clear-cutting requires the most road building due to the large number of trees harvested.
Selective cutting minimizes the impact on forest ecosystems.
Given that most people live in urban areas, why should rural areas be preserved?
They provide crucial infrastructure.
They provide ecological services.
They contain greenbelts.
None of the above
Which of the following best describes why many people in the world go hungry?
