_________1. The heat from inside the Earth is collected in a geothermal power plant by drilling a hole in the ground at great depth. _________2. The heat is used to boil water to produce steam that turns the turbine. _________3. Mechanical energy transforms into sound energy. _________4. Geothermal energy is a clean and renewable source of energy that can be used by harnessing heated water from within the Earth and converting it to steam so that it can move turbines and generate electricity. _________5. Tapping heat within the Earth is a source of expensive, clean, available, and non-renewable energy. _________6. Geothermal energy can be generated in four ways. _________7. In geothermal heat pumps, the heat from deep inside the Earth is used to produce steam to generate electricity. _________8. In Geothermal power plants, the heat comes from close to the Earth’s surface to heat water or provide heat for buildings. _________9. The heat of the Earth warms up water which is trapped in rock formations beneath its surface. ________10. The mechanical energy from the turbine is transferred to the generator.
