Chapter 25 Review Game Questions What is the primary source of energy on Earth? Sun What is an example of a consumer? Humans, Animals, etc. What is an example of a producer? Plants What are the 3 types of fossil fuels? Coal, Oil (Petroleum), and Natural Gas What are 3 types of biomass? Fecal Material, Wood, and Field Crops What are the 2 types of solar power? Active and Passive In active solar, what are the thin silicon based wafers that convert sunlight to electrical energy? Photovoltaic Cells Burning fossil fuels is not energy efficient. How much of the energy potential is actually used? About 1/3 Biomass and fossil fuels burn due to the presence of this? Hydrocarbons What do we call a spongy material made of decomposed plants and is a precursor of coal? Peat In order from least amount to greatest amount of carbon, list the 3 types of coal? Lignite, Bituminous, and Anthracite What are the main two types of biofuel? Ethanol and Biodiesel What do you call the process in which nuclear power plants create heat? Nuclear fission What are the six alternative energies? Underline which one or ones are nonrenewable. Nuclear, hydro, solar, geothermal, biofuel, and wind What is a key difference between biomass and fossil fuels? Biomass is renewable, fossil fuels are nonrenewable Where would be a good place to set up a geothermal power plant? Between tectonic plate boundaries In the US and globally, what was the number one fuel source? Oil/Petroleum What is a common disadvantage to solar, hydro, nuclear, wind, and geothermal? The initial costs are expensive What is the ability to do work called? Energy What do we call the process for getting oil and natural gas out of the ground? Hydraulic fracturing (Fracking) What is one way to improve energy efficiency? Using energy efficient appliances, etc. What is a common process involved in a nuclear power plant, a coal burning power plant, and geothermal? Turbines powered by steam What is the global management of Earth’s natural resources to ensure that current and future energy needs will be met without harming the environment called? Sustainable Energy The simultaneous production of two usable forms of energy. Cogeneration The amount of work produced compared to the amount of energy used. Energy Efficiency What percent of energy in industrialized countries is renewable? Nonrenewable? 10% renewable, 90% nonrenewable
