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.
Which of these can be recycled in an attempt to conserve resources?
gasoline
sunlight
aluminum
natural gas
Wind is becoming more common as a source of energy. Wind farms require large open spaces for the wind turbines. A negative consequence of this technology is wind turbines...
are an inexpensive source of energy.
cause little pollution to the environment.
may hurt the flying animals in the area.
are a renewable source of energy.
Which BEST explains what scientists are referring to when they use the term conservation?
nonliving parts of the environment
living organisms in the environment
health of the living organisms in the environment
protection, management, and renewal of resources
Which topic area would be the BEST to research to find ways of reducing environmental problems caused by humans?
converting sunlight into electricity
looking for new coal reserves
finding reservoirs that contain oil
converting forests into farmland
Which human activity contributes to the formation of acid rain?
using too much fertilizer in agriculture
cutting down large areas of tropical forests
burning fossil fuels such as coal and gasoline
using chemicals that destroy ozone in the stratosphere
Which is an example of a renewable energy resource?
biomass
coal
gas
oil
Which best describes a potential environmental consequence of cutting down large areas of forests?
The amounts of oxygen and carbon dioxide in the atmosphere will increase.
The amounts of oxygen and carbon dioxide in the atmosphere will decrease.
The amount of oxygen in the atmosphere will decrease while the amount of carbon dioxide in the atmosphere will increase.
The amount of oxygen in the atmosphere will increase while the
amount of carbon dioxide in the atmosphere will decrease.
Which energy source would be most affected by the depletion of water from rivers and streams?
fossil fuel
hydroelectric
wind power
nuclear power
Why is renewable energy a better alternative to nonrenewable energy?
Renewable energy is less expensive than nonrenewable energy.
Renewable energy is readily available, while nonrenewable energy supplies are limited.
Renewable energy requires much less equipment maintenance than nonrenewable energy.
Renewable energy harms the environment, while nonrenewable
energy is environmentally friendly.
Which is the most negative environmental consequence of building dams for hydroelectric power?
air pollution
chemical spills
water pollution
habitat destruction
Which energy source would be most affected by the depletion of uranium?
fossil fuels
wind power
nuclear energy
hydroelectricity
Which best explains why some people are against the use of nuclear energy?
There is not enough oil available.
There is not enough water available.
There is a risk of reactors working too slowly, wasting time, and not being cost-efficient.
There is a risk of reactors losing control, spreading radiation, and causing serious injuries.
Which best describes a disadvantage of using wind power to generate electricity?
The technology used to generate electricity from wind is expensive.
Much of the energy in wind power is lost when it is converted to
electricity.
The source of wind needed to generate electricity is variable and unpredictable.
The amount of electrical energy produced from wind power is too great for power lines to withstand.
Which is a disadvantage of relying on solar energy?
Solar energy is only available after the sun sets.
Solar energy creates a large amount of air pollution.
Solar energy can only be captured during daylight hours.
Solar energy is weak and does not provide adequate energy.
Which best describes why fossil fuels are most often used for energy in the United States?
Fossil fuels are found everywhere in the world.
Fossil fuels can be quickly replaced in nature.
Fossil fuels are easy to transport and burn.
Fossil fuels have no harmful waste products.
