| Question | Answer |
|---|---|
| energy | The ability to do work or cause change. |
| kinetic energy | The energy an object has because of its motion |
| potential energy | Stored energy an object has because of its position or condition. |
| combustion | A chemical process of burning a fuel in oxygen that releases heat and light. |
| energy efficiency | The percentage of energy put into a system that is converted into useful work, not lost as waste heat. |
| renewable energy | Energy from sources that are naturally replaced in a short time, such as sunlight, wind, moving water, and biomass. |
| nonrenewable | Energy from sources that exist in limited amounts and will run out, such as coal, oil, and natural gas. |
| electricity | A form of energy resulting from the movement of charged particles (electrons) through a conductor. |
| srip mining | A surface mining method where layers of soil and rock are removed to expose mineral deposits near the surface. |
| surface mining | Mining that removes minerals or other materials that are near Earth’s surface. |
| petroleum | A liquid fossil fuel (crude oil) formed from ancient marine organisms and used to make fuels and many products. |
| petrochemicals | Chemicals made from petroleum or natural gas that are used to make plastics, fertilizers, medicines, and other products. |
| oil sands | Deposits of sand or clay mixed with heavy, thick oil (bitumen) that can be processed into usable oil. |
| oil shales | Sedimentary rocks that contain solid organic material (kerogen) that can be heated to produce oil. |
| methane hydrate | Ice-like crystals under the ocean floor or in permafrost that trap methane gas inside water molecules. |
| acid drained | Acidic water that forms when mining exposes certain rocks to air and water, causing chemical reactions that release acids into nearby water. |
| energy conservation | The practice of using less energy or using energy more wisely to reduce waste. |
| nuclear energy | Energy released from the nucleus of an atom, usually through nuclear fission in power plants. |
| nuclear fission | The process of splitting a large atomic nucleus into smaller nuclei, releasing a large amount of energy. |
| nuclear reactor | A device in a power plant where controlled nuclear fission reactions occur to produce heat and generate electricity. |
| meltdown | A serious nuclear power plant accident in which the fuel rods overheat and melt, potentially releasing radiation |
| nuclear wastrel | – Same as #19: splitting large atomic nuclei to release energy. |
| nuclear fission |
