- 6. partially decayed plant matter found in bogs, used as fuel
- 7. A reaction that occurs when lighter nuclei are forced together to produce heavier nuclei, resulting in a release of vast amounts of energy
- 8. a combustible black or dark brown rock consisting mainly of decayed plant matter, found mainly in underground deposits and widely used as fuel.
- 13. A nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy
- 14. electricity generated by the kinetic energy of moving water
- 15. a naturally occurring element used by humans to produce energy in nuclear power plants
- 16. fuels a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
- 17. Energy derived from the heat in the interior of the earth
- 18. (oil) A flammable, yellow-to-black liquid composed of hydrocarbons occurring naturally beneath Earth's surface; it is a nonrenewable fossil fuel processed to make gasoline used in vehicles.
