vocab. for DSST Env.Sci. from Environmental Science by Karen Arms
| Question | Answer |
|---|---|
| atomic explosion | uncontrolled release of nuclear energy |
| biomass | organic matter in plants or plant products |
| electric generator | device that converts mechanical energy into electric energy |
| electricity | flow of electrons, the tiny particles that whirl around the nucleus of an atom |
| energy conservation | use of energy efficiently without necessarily reducing effectiveness |
| fossil fuel | organic substance such as coal, oil, and natural gas that is used as an energy source and is formed from the remains of organisms that lived millions of years ago |
| gasohol | blend of gasoline and alcohol for motor fuel |
| geothermal energy | energy that is drawn from heat within the Earth and used to drive electric generators |
| hydroelectricity | electricity produced by converting the energy of moving water |
| nuclear energy | energy that exists within the nucleus of an atom |
| nuclear fission | process in which subatomic bonds that bind the components of the atomic nucleus are broken apart, releasing huge amounts of energy |
| nuclear fusion | the process in which lightweight atomic nuclei combine to form a heavier nucleus, releasing huge amounts of energy; basically the opposite of nuclear fission |
| passive solar heating | system in which sunlight is used to heat buildings directly without pumps or fans |
| pressure vessel | steel casing containing cooling fluid that surrounds the reactor in a nuclear power plant |
| reactor | main element of nuclear power plant from which a steady, manageable amount of energy is released |
| solar cells | devices that convert the sun’s energy directly into electricity |
| solar energy | energy from the sun |
| solar water heating | system that uses solar energy to heat water for household use |
| wind energy | energy captured as wind turns a turbine and generates electricity; an indirect form of solar energy |
