• garbage dump
• oil shale
• acid drainage
• petrochemicals

nuclear fission

• a reaction in which two nuclei combine to form a nucleus with the release of energy 
• when hydrogen atoms fuse together to make helium producing energy
• Potential Energy stored in the Nucleus of an Atom
• a device in which a nuclear reaction is maintained and controlled for the production of nuclear energy

If fossil fuels continue to be used at their current rate, which will probably be used up first?

• coal
• oil
• natural gas
• methane hydrate

What is the purpose of the chain reaction in a nuclear power plant?

• to produce the heat and steam that turn the turbine
• to produce neutrons that turn the generator
• to cause steam to condense into liquid water
• to reduce the temperature in the cooling tower

The energy trapped in fossil fuels came from the energy plants converted during photosynthesis. This trapped energy is

Coal deposits that are deep underground must be extracted by subsurface mining rather than by strip-mining because strip-mining would

• be too dangerous.
• be too expensive.
• require removal of large amounts of rock and soil.
• require that removed rock and soil be put back into the hole.
