Radiation
Latitude
El Nino
La Nina
Kyoto Protocol is primarily about
reducing emissions of greenhouse gases
cleaning up of the world's oceans
reducing use of plastic products
sustainable peace
The critical difference between today’s global warming and Earth’s previous climate changes is that:
Scientists can now save all species from extinction by genetic engineering
Global warming may occur much more rapidly than it did during previous climate changes
Human-made chemicals such as CFCs do not influence global warming
Previous changes in climate only happened once every 200 years
Methane is most responsible for the green house effect.
True
False
Which of the following would not be a consequence of a rise in global temperature?
Rising sea level
Increased frequency of major storms
Decreasing sea levels
Increased frequency of major droughts
CFCs are depleting the Ozone.
True
False
What are some long-term effects of air pollution on humans?
Lung Cancer
Alzheimer's disease
Emphysema
All of these are long-term effects
Which of the following is NOT a strategy for controlling air pollution?
Remove particulates by trapping them in a porous mesh
Pass air through an electrically charged plate to attract particulates
Limit production of air pollution in the first place
All are ways to control air pollution
Industrial factories, Burning fossil fuels, and Car exhaust all contribute to air pollution.
True
False
Which of the following definitions best describes acid shock?
The sudden runoff of large amounts of highly acidic water into lakes and streams
The contamination of the atmosphere by the introduction of pollutants
Rain, sleet, or snow that contains a high concentration of acids
Contamination of water by waste matter of other material
Eutrophication is caused by
excess nutrients building up in the water.
industrial point-source pollution.
unlined landfills and septic tanks.
wastewater from homes mixing with drinking water.
Determine the difference between Primary and Secondary pollutants.
Secondary are things like Nitrous Oxide and VOCs Primary are acid rain and smog
Primary react with the atmosphere and secondary are put directly into the air
Secondary create a chemical reaction with the air and primary are put directly into the atmosphere
Primary pollutants have a stronger pH and secondary and a weaker pH
Why is the process of “fracking” controversial?
The 2005 Energy Policy Act provides industry exemption from the Clean Water Act
Fracking fluid contains hazardous chemicals
The EPA discovered contaminated groundwater near fracking sites
All are reasons the fracking process is controversial
The biggest point-source of oil in the ocean comes from oil running off from streets into storm drains
True
False
Most of Earth’s fresh water is frozen at the North and South Poles
True
False
How is freshwater used in industry?
Generate power
Manufacturing processes
Disposal of waste products
All of the above
How is electricity generated in a coal-fired power plant?
The heat generated from burning coal turns water into steam, which turns a turbine, thus running the electric generator
The coal is heated until it vaporizes. The coal vapor is distilled in the combustion chamber, which powers the electric generator.
The turbine breaks down the coal into a liquid fuel that powers the electric generator, thus producing an electric current.
The coal is burned, which heats the air. The hot air rises and turns the electric generator’s turbine.
In a nuclear power plant,
solid uranium pellets are bombarded with steam in the control rods
three pipe circuits pump water through the reactor, turbine, and cooling tower.
nuclear fusion superheats water in the reactor, causing steam to power the turbine.
solid neutron pellets undergo a chain reaction and release massive amounts of heat.
Most American citizens live in rural areas
True
False-Urban Areas
False- Producing farms
False- there is an equal distribution of people in both urban and rural areas
Increased precipitation is a side effect of heat islands
True
False
Traffic jams, substandard housing, and polluted air and water can be caused by rapid growth in cities, a phenomenon known as the urban crisis.
False-urban sprawl
False-urbanization
True
False-infrastructure
How do people use land?
Grow Crops
Harvest Wood
Raise Livestock
Build Cities
Food production has not been increasing as fast as the human population which is why many people in the world go hungry.
True
False
Genetic engineering of food crops
continues to be debated among scientists
is only used with corn
must be disclosed on food ingredient labels
Leave the land unused for a time, Eliminate (removed) invasive plants, and Limit herd size are ways to sustain Rangeland.
True
False
Why is it important to preserve farmland?
Farmland provides crops and fruits to support urban and rural populations.
Farmland provides an important oxygen source for urban areas.
Farmland moderates the temperature of urban areas.
All of the above
Integrated pest management can include chemical pest control, biological pest control, and a mix of farming methods.
True
False
Making products from recycled materials often saves energy and other resources during the manufacturing process.
True
False
the Landfill Act requires producers of hazardous wastes to document how their wastes are handled
False-the Superfund Act
True
False-the Hazardous Waste Act
False-the Resource Conservation and Recovery Act
