What five-syllable term describes power produced when falling water turns turbines connected to electric generators?

• A. Tidal
• B. Solar
• C. Hydroelectric
• D. Geothermal

Answer: (C)

The concept here is generating electricity from moving water by letting falling water spin turbines that turn generators. When water falls, its potential energy becomes kinetic energy and drives the turbines, which in turn power the electric generators to produce electricity. The term that describes this kind of power is hydroelectric, and it fits the description exactly because it combines water (hydro) with electricity (electric). The word is five syllables: hy-dro-e-lec-tric, with hydro contributing two syllables and electric contributing three. Other energy sources mentioned—tidal, solar, geothermal—refer to different methods of producing electricity and don’t describe the falling-water turbine mechanism.
