Energy Review

Master energy sources & impacts with our review worksheet!

Most electricity in the United States is generated using coal, natural gas, nuclear energy, or hydropower. Which of these adds carbon dioxide to the atmosphere? nuclear energy and hydropower hydropower and coal natural gas and nuclear energy coal and natural gas What would most likely happen to the cost of gasoline if the supply of petroleum decreased? Cost would increase. Cost would stay the same. Cost would decrease. Gasoline is not made from petroleu Which is the most negative consequence of building dams for hydroelectric power? Air Pollution Habitat Destruction Chemical Spills Generation of Radioactive Waste Which of the following is a renewable resource? Coal Minerals Sunlight Petroleum The burning of fossil fuels has been attributed to the accumulation of greenhouse gases and rising global temperatures. Which best explains this? Wind energy is produced during the burning of fossil fuels. Solar energy is collected during the burning of fossil fuels. Thermal energy is released during the burning of fossil fuels. Electrical energy is wasted during the burning of fossil fuels. Which is the best example of the management of natural resources? Drilling oil wells to produce more energy. Limiting research of alternative energy resources. Increasing the use of current energy resources. Managing and caring for current energy resources. Which best describes a potential environmental consequence of cutting down large areas of forests? The amount of oxygen and carbon dioxide in the atmosphere will increase. The amount 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 increases. The amount of oxygen in the atmosphere will increase while the amount of carbon dioxide decreases. Which of these is most necessary for the production of geothermal energy? Thick Crust Hot Rock Fossil Fuels Warm Climate Which form of energy production generates a radioactive waste product? Nuclear Power Coal Combustion Wind Turbines Solar Cells Which is a consequence of producing electricity through wind energy? Air Pollution Noise Pollution Increased Water Temperature Release of Greenhouse Gases Which best explains why fossil fuels should be conserved? They are inexpensive. They are in limited supply. They are dangerous to handle. They do not cause pollution when used. Which best explains why energy transfer is not 100% efficient? Some energy is destroyed during the transfer. Some energy cannot be transferred. Some energy is lost the the environment as heat. Some energy is transformed into other types of matter. Which method of energy transformation has the least potential environmental impact? Photovoltaic cells transfer solar energy into electrical energy. Car motors transfer electrical energy into mechanical energy. Power plants transfer nuclear energy into electrical energy. Burning oil transforms chemical energy into thermal energy. Which is a disadvantage of relying on solar energy? Solar energy creates a large amount of air pollution. Solar energy can only be captured during daylight hours. Solar energy is only available after the sun sets. Solar energy is weak and does not provide an adequate amount of energy. Which best describes a process that depletes an organic renewable resource? A car producing emissions from combusting petroleum. The burning of coal in a power plant. Cutting down trees to burn as biomass. The capturing of sunlight in a photovoltaic cell. Energy transformation occurs when... Energy changes from one form to another. Energy is created through conduction. Energy is destroyed though a chemical reaction. Energy passes, in the same form, from one object to another. A nuclear power plant at an ocean side site will use seawater to cool the reactors. They will return the water to the ocean. Which unintended consequence should be considered? Number of kilowatts of power produced per home. The effect of the warmed water on the marine ecosystem. The impact of other energy producing resources. Energy use per person. Which is most likely the reason wind energy is not widely used as a replacement for fossil fuels? Wind energy is an indirect form of solar energy. Energy from wind is too expensive to produce. Producing energy from wind causes too much pollution. Few places are windy enough to produce sufficient energy. The burning of fossil fuels has added pollutants that contain sulfur to the air. These pollutants have contributed to which of the following? Temperature Inversions Drought Acid Rain Tornadoes Which energy conversion is taking place when your car uses gasoline? Mechanical → Electromagnetic Chemical → Mechanical Thermal → Electrical Mechanical → Electrical
