Most of the public health impacts from air pollution are the result of
continuous exposure to many pollutants.
A lake that averages 20 feet of water depth experiences extreme eutrophication. In this lake, we would expect to find
dead fish, low numbers of living fish, low oxygen levels, and very cloudy water.
A new gravel road is cut into the side of a mountain just north of Anchorage, Alaska. As the snow melts in June, the fine gravel and sediments of the disturbed region quickly tumbles into the bottom of nearby streams and shades out light. The addition of this fine gravel and sand changes the stream by
decreasing the number of plants and animals that live there.
A human source of greenhouse gases is/are
factories.
Ice cores show a strong relationship between temperatures and
greenhouse gases.
Stratospheric ozone protects Earth's surface from
harmful ultraviolet radiation.
The particles created through photochemical breakdown that oxidize many gaseous pollutants are
hydroxyl radicals.
Cattle production in the United States and other developed nations involves the use of CAFOs. This practice of raising animals for food has caused all of the following except
improvements in water quality.
Acid precipitation has a pH
less than 5.5.
The water conditions in an oligotrophic lake reveal a body of water that most likely has
low levels of nutrients and high levels of oxygen.
Reducing the world consumption of ______ would reduce greenhouse gas emission, water usage, and increase food for human consumption.
meat
Global warming is raising sea levels because of
melting ice and thermal expansion.
Secondary air pollutants are formed by
primary pollutants reacting with other compounds in the atmosphere.
Pollutants in the lower troposphere are typically
removed within hours or days.
Although the Green Revolution has greatly reduced world hunger and malnutrition, it has also
required high levels of increasingly expensive fertilizer and pesticides.
Pollutants in the stratosphere are typically
resistant to cleansing.
An example of a secondary air pollutant is
sulfuric acid.
Sediments move in the water by
suspended and bed loads.
Ocean circulation is caused by changes in
temperature and salinity.
A temperature inversion occurs when
the air near the ground is cooler than the air directly above it.
About 150 years ago, agriculture underwent a revolution due to
the industrial revolution, which brought changes in agricultural technology.
Which disease causes a loss of $2.65 billion because of CAFOs?
Salmonella
Climate is controlled by
All of these
Which of the following describes weather?
A rainfall during a Spring afternoon.
In order to prevent diseases transmitted by water,
All of these
Increasing the size of urban area leads to
All of these
The global food crisis was caused by
All of these
We can observe climate change happening through direct measurements of
All of these
Which of these is an example of radiative forcing?
All of these
Which of the following methods of fighting eutrophication will not increase sunlight to the bottom of a pond and protect aquatic organisms?
Applying herbicides
In which of the following regions would we most expect to find industrial smog?
Around an industrial town that burns coal to generate electricity and make steel
What do wastewater treatment facilities primarily depend upon for the breakdown of pathogenic organisms and organic materials in wastewater?
Bacterial decomposers and detritus feeders
The increasing abundance of mercury in larger fish is an example of
Biomagnification
Which of the following is not a source of natural air pollution?
Car exhaust
1/3 of what crop in the U.S. is devoted to ethanol production for biofuels?
Corn
Which of the following wastewater pollutants is removed during primary treatment?
Debris and Grit
Which of the following wastewater pollutants is removed during secondary treatment?
Dissolved Organic Matter
We eat food to gain
Energy and nutrients
Which of the following U.S. national parks would be mostly eliminated by a 1-meter rise in sea level?
Everglades National Park
Which one of the following represents a way to reduce point-source pollution contributing to cultural eutrophication?
Remove nutrients from sewage-treatment discharge pipes
Which of the following is a disadvantage or urbanization?
Risks to public health
Which one of the following best illustrates a nonpoint source of pollution?
Storm-water drainage from the parking lot around a football stadium
Why are organic foods more expensive than conventional foods?
Subsidies are given to conventional farmers.
Which of the following is not a potential benefit of GMOs?
Super weeds
What is the main source of energy driving natural processes on Earth's surface?
The sun
The vast majority of scientists studying Earth's climate agree human activities are causing global warming.
True
Which of the follow does not describe subsistence farming?
Uses many modern agricultural practices
For more than 20 years, scientists have been analyzing expected climate change and the impact on crops grown in particular regions. For example, states that typically plant corn and soybeans may need to switch to growing cotton, which is more tolerant of higher temperatures. Such a change is an example of
adaptation.
If you live in the United States, chances are that you have consumed some processed food that includes bioengineered (GMO) ingredients
almost every day
Based on radiative forcing values (W/m2), __________ is responsible for most human-related radiative forcing
carbon dioxide
An example of a primary air pollutant is
carbon monoxide.
Most of the successful urban plans that have made cities more livable and sustainable have incorporated
the use of renewable energy and the recycling of all wastes.
Sediments act as water pollutants because
they reduce light penetration.
High concentrations of nutrients become pollutants because
they stimulate undesirable plant growth.
Most of the weather in the world is based upon changes in the moisture, pressure, and/or temperature of the
troposphere.
The lower atmosphere where our weather, water vapor, and clouds occur is called the
troposphere.
A natural source of greenhouses gases is/are
volcanoes
Urban sprawl has resulted in
wildlife habitat fragmentation and environmental degradation.
Are plants more susceptible to air pollution than humans?
yes
