What is true about geothermal plants?
Geothermal power plants use hydrothermal resources that have both water (hydro) and heat (thermal). Geothermal power plants require high-temperature (300°F to 700°F) hydrothermal resources that come from either dry steam wells or from hot water wells.
Which is true about nuclear fission?
Nuclear fission is the process during which a heavy nucleus splits into two intermediate-sized nuclei after being struck by a neutron. The mass of the products of a nuclear fission reaction is less than the mass of the original elements. … Antiparticles are produced in nuclear reactions. All particles have antiparticles.
Which best describes nuclear fusion quizlet?
Which best describes nuclear fusion? Nuclei combine to form a heavier nucleus, releasing energy.
What is geothermal energy for kids?
Geothermal energy is heat that comes from inside Earth. It is an alternative energy source that can be used for cooking, bathing, and heating. It can also be converted into electricity. Geothermal energy is available anywhere on Earth’s surface.
What are the characteristics that describes fission fusion and both?
Both fission and fusion are nuclear reactions that produce energy, but the processes are very different. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
Is wind energy from the sun?
Wind energy is actually a byproduct of the sun. The sun’s uneven heating of the atmosphere, the earth’s irregular surfaces (mountains and valleys), and the planet’s revolution around the sun all combine to create wind.
How geothermal energy is formed?
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. The steam rotates a turbine that activates a generator, which produces electricity.
Is geothermal energy or solar energy better?
Why is geothermal energy more reliable than solar energy?
Geothermal Is a Reliable Source of Renewable Energy
Geothermal energy also has many advantages when compared to other renewable sources like solar, wind or biomass. It is an exceptionally constant source of energy, meaning that it is not dependent on neither wind nor sun, and available all year long.
What are uses of geothermal energy?

What is geothermal energy Mcq?
This set of Energy Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Geothermal Energy”. Explanation: The process of producing energy by utilizing heat trapped inside the earth surface is called Geo thermal energy. Energy present as heat in the earth’s crust.
Is wind a energy?
Wind is actually a form of solar energy. Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth’s surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid.
