The Sun and other stars make heat & light by nuclear reactions. Nuclear energy is produced two different ways: In one, large nuclei are split to release energy. In the other method, small nuclei are combined to release energy.

Can nuclear energy be used everywhere?

Yes. There are virtually no physical limitations to where nuclear power can be used. Nuclear reactors have already been used on land, air and sea... and submerged and in space. Not only we humans use nuclear energy, but it is the primary source of energy in natural processess in the world too. Life on earth depends on the sun's energy, which in part is produced by nuclear fusion in the heart of the star.


What is hydro thermal energy kids version?

Hydrothermal energy is generated through the earth's hot water. The water is produced underground, and heated by the earth's thermal heat.


How many tnt to destroy the earth?

It may take a thousand of tons on TNT to pack a nuclear bomb. But to destroy the earth, it may take billions to trillions tons of TNT plus a nuclear igniter to blow the earth to bits of dust.


What is the roots of all from of energy?

Historically, it was the Sun, which created the plant life and animal life used to make energy, and which formed fossil fuels. Even hydroelectric energy is dependent on solar heating to return water to its sources. And because we now have nuclear energy, the answer could be "from nuclear reactions" -- fusion on the Sun and fission in nuclear generators. This, however, neglects the use of tidal energy and geothermal energy. Tidal energy is caused primarily by the gravitation of the Earth and Moon, not the Sun. And geothermal energy is drawn from magma formed by crustal movements, which ultimately are driven by the Earth's hot core. The heat there is a combination of radioactive heat, tidal heat from the Sun's gravity, and energy left from the formation of the planet. The ultimate source, therefore would have to be "gravity" because it formed the Sun and planets, keeps fusion going, moves the tides, and keeps the Earth's core hot enough to produce tectonics.


Energy source of most life on earth?

Most life on earth, gets there energy source from the sun, that is assuming that the majority of life on earth are autotrophs (plants). They get this energy by photosynthesising and getting a energy source called glucose, which is used in nearly all organisms on earth... they can then use glucose as a respiratory substrate, for respiration... Hope this helps :)

Where is the majority of the nuclear energy that lands on earth produced and what are three ways this energy is used once it reaches Earth's surface?

The majority of nuclear energy on Earth is produced in the core of the sun through nuclear fusion reactions. Once this energy reaches Earth's surface, it is used for electricity generation in nuclear power plants, medical applications such as cancer treatments using radiation therapy, and research purposes like nuclear physics experiments.


What is an energy that we do not get from the sun?

Nuclear energy (ie that produced on earth from uranium)


Is nuclear energy mined?

No, nuclear energy is not mined. Nuclear energy is produced by splitting atoms in a process called nuclear fission, which releases energy. The fuel used in nuclear reactors, such as uranium or plutonium, is mined from the earth.


Is all nuclear energy produced the same way?

All useful nuclear energy produced on Earth comes from nuclear fission of U-235 and/or Pu-239, in a variety of different reactor designs. In the stars it comes from fusion of hydrogen, not fission.


Is solar the same as nuclear?

No, solar and nuclear energy are not the same. Solar energy is produced by harnessing sunlight using photovoltaic cells, while nuclear energy is generated through splitting atoms in a process called nuclear fission. Each technology has different methods of energy production and different environmental impacts.


The process by which heat energy is transmitted from the sun to the earth?

Radiation, called Solar Radiation. Radiant energy in produced in the sun by nuclear fusion.


What is the most powerful man made energy source on earth?

Nuclear energy is considered one of the most powerful man-made energy sources on Earth due to its high energy density and ability to generate large amounts of electricity. It is produced through nuclear reactions, such as fission or fusion, which release immense amounts of energy.


Is the produced from a meteor is produced by nuclear fusion?

No, the light produced from a meteor is not due to nuclear fusion. When a meteoroid enters Earth's atmosphere, the friction with air molecules causes it to heat up and glow, resulting in the light we see. This phenomenon is known as "incandescence."


Where is thermal energy produced?

Thermal energy is produced in various ways, such as through combustion of fuels like coal, natural gas, or oil in power plants, through nuclear reactions in nuclear power plants, or through renewable sources like geothermal energy from the Earth's heat or solar energy from the sun.


How is the sun an example of nuclear energy?

The Sun is an example of nuclear energy because it produces energy through nuclear fusion reactions in its core. These reactions involve the combining of atoms to release energy in the form of light and heat. This process is similar to how nuclear power plants on Earth generate electricity using nuclear reactions.


How is the energy that reaches Earth from the sun produced?

The Sun gets its energy from nuclear fusion. Mainly, converting hydorgen-1 into helium-4.


What process does the sun do to give heat to earth?

The sun generates heat and light through nuclear fusion in its core. This fusion process converts hydrogen into helium, releasing vast amounts of energy in the form of heat and light. This energy is then radiated out as sunlight, which warms the Earth.
