m hich of these statements about geothermal energy is false? A The hot water produced from the geothermal wells can be directly circulated through buildings or pumped through a heat exchanger that transfers the heat to a building. B The major regions of geothermal development are in the most volcanically and tectonically active regions of the world. The hot water produced from the geothermal can also be used to produce electricity in a geothermal power plant. Electricity is generated when geothermal heat produces steam that turns turbines on a generator. The energy is accessed through geothermal wells which are drilled into the Earth's crust at approximately a depth of 3 to 10 kilometers. The heat is extracted with a variety of methods but in most cases is drawn from the earth using water and steam. E Geothermal energy production is safe, cheap, and reliable. It provides consistent power generation, poses no risk to the earth, and produces no emissions. F Geothermal refers to producing…
