Which of the following best describes an environmental problem that is often linked to the process of fracking?

• Fracking operations require large tracts of land, which degrades habitat and harms wildlife.

• Fracking can increase stream flow and water volume, disrupting fish migration pathways.

• Wastewater from fracking operations is injected into porous rock formations, which can induce seismic activity.

• Excessive nutrients, such as nitrogen and phosphorus, run off the land near fracking sites, which can lead to large algal blooms in nearby waterways.

The map below shows energy-dependent and energy-independent countries around the world.

Which of the following statements about the global distribution and use of fossil fuels is best supported by the data on the map?

• Saudi Arabia and Australia produce large volumes of fossil fuels with relatively low energy demand.

• The United States produces more fossil fuels than it consumes.

• Japan has the greatest energy independence because there are abundant reserves of fossil fuels present in the country.

• Russia and Indonesia are reliant on the export of other nations for their fossil fuels.

After the Industrial Revolution, the use of fossil fuels increased significantly. Despite the documented environmental effects of these resources and the availability of renewable resources, the use of nonrenewable sources continues.

Which of the following statements best explains why there is continued widespread use of nonrenewable fossil fuels in energy production in the United States?

• Established technology and transportation infrastructure for fossil fuels allows these resources to be converted into energy to meet consumer demand.

• Fossil fuels are significantly cheaper than renewable resources, so they do not require government subsidies, which ultimately saves the government money.

• The environmental effects of fossil fuels are easy to mitigate, while the environmental effects of renewable resources are difficult to understand and reverse.

• Fossil fuels will always be present and are plentiful in quantity, so there is little pressure to find a replacement for them as an energy source.

Which of the following best describes why people in less developed countries use wood as a primary energy source?

• The infrastructure required to transport wood is well established.

• Wood produces fewer carbon emissions than other energy sources, such as geothermal or natural gas.

• Wood can be converted to peat and cheaply burned for fuel.

• Wood, in the form of firewood and charcoal, is often readily available.

Which of the following statements best describes a difference between nonrenewable and renewable energy sources?

• Nonrenewable energy sources release carbon dioxide when used, whereas renewable energy sources do not release carbon dioxide.

• Renewable energy sources are often obtained a long distance away from the customer, whereas nonrenewable energy sources are obtained locally.

• Renewable energy sources can be replaced naturally at current consumption rates, whereas nonrenewable energy sources cannot be replaced easily.

• Renewable energy sources produce energy that can be recycled after use, whereas the energy from nonrenewable energy sources cannot be recycled.

• A 

• B

• C

• D
