II. Read the passage and choose the correct answer for each question (1 point)
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun.
Wind flow patterns are changed by the earth's terrain, bodies of water, and vegetative cover. This wind
flow, or motion energy, when "harvested" by modern wind turbines, can be used to generate electricity.
Wind turbines are available in a variety of sizes, and therefore power ratings. The largest machine has
blades that span more than the length of a football field, stands 20 building stories high, and produces
enough electricity to power 1,400 homes. A small home-sized wind machine has rotors between 8 and 25
feet in diameter and stands upwards of 30 feet, and can supply the power needs of an all-electric home or
small business, utilityscale turbines range in size from 50 to 750 kilowatts. Single small turbines, below
50 kilowatts, are used for homes, telecommunications dishes, or water pumping.
