Why is it NOT a safe practice to place a fuel depot over an aquifer (an aquifer is a rock layer that collects our drinking water)?

• Aquifers are too high up in the mountains.

• The weight of the depot is too great over the aquifer.

• The fumes escaping from the fuel depot are explosive.

• If the fuel leaks, the water in the aquifer will become contaminated.

Acid rain can damage limestone buildings and marble statues. It can also harm organisms living in ponds and other ecosystems. Which pollutant in the atmosphere causes MOST of the acid rain?

• fluorocarbons from aerosol spray cans

• nitrous oxide from volcanic eruptions

• sulfur dioxide from burning fossil fuels

Fossil fuel and rechargeable batteries power most hybrid cars. Which of the following is the BEST reason to consider using hybrid cars instead of conventional cars?

• Hybrid cars have less of a negative impact on the environment than conventional cars.

• Hybrid cars are less likely to have mechanical failure than conventional cars.

• Hybrid cars use new technology, so they are more convenient than conventional cars.

• Hybrid cars are less expensive than conventional cars.

More sulfur dioxide is being added to the atmosphere. How will this MOST likely affect the hydrosphere?

• There will be a decrease in sea level.

• The acidity of the ocean will increase.

• There will be an increase in fresh water.

• The temperature of the oceans will decline.

Which of these is a renewable resource found in Nevada?

• zincmetal

• gravel deposits

• petroleum products

• geothermal energy

Jamie read that the amount of fossil fuels that are available will eventually decline, leading to a short supply of fuel for automobiles. What is the MOST likely effect of a fossil fuel shortage?

• More people would use airplanes for travel.

• The fossil fuels would be manufactured in factories.

• There would be more research on the use of alternate fuels.

• The technology will be focused on cars that do not use energy.
