Answers & Comments
Answer:
15. B. Lahar
Explanation:
Lahar. It is a rapidly thick mixture of volcanic material and water, usually generated along river channels by extreme rainfall.
16. A. Ash Fall
Explanation:
Ashfall. It is also known as tephra fall. This is the showering of fine-to-coarse-grained volcanic material and other airborne products of a volcanic eruption.
17. B. Ground
Explanation:
The geothermal heat pump, also known as the ground source heat pump.
18. C. Steam
Explanation:
Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface.
19. A. earth, heat
Explanation:
The word geothermal comes from two Greek words – 'geo' meaning of the Earth, and 'thermal' meaning heat.
20. A. daytime
Explanation:
Geothermal energy is available 24 hours a day, 365 days a year.
21. A. geothermal
Explanation:
Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth.
22. A. electricity
Explanation:
The slow decay of radioactive particles in the earth's core, a process that happens in all rocks, produces geothermal energy.
23. D. Where tectonic plates meet and underground
Explanation:
Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth's crust and can be found as far down to the earth's hot molten rock, magma.
24. C. Environmentally friendly
Explanation:
Environmentally Friendly. Geothermal energy is more environmentally friendly than conventional fuel sources such as coal and other fossil fuels.
25. D. That it generates greenhouse gases
Explanation:
But the use of geothermal energy can greatly minimize these impacts, resulting in environmental benefits for many states and local communities with growing energy needs. Geothermal energy is clean, sustainable energy.
