Fusion. Fusion requires very high temperature and pressure. So on earth we use
a critical mass of weapons grade uranium to start a fission chain reaction which
enables a fusion reaction in hydrogen. Fusion is of course more powerful than fission

It does not occur in the sun, which gets its energy from nuclear fusion. This occurs in the central part of the sun.

Truly speakingg, Uranium fission powers Sunlight according to the new study.

No nuclear fusion takes place only in the core of sun, it doesn't take place on the surface of a star

Why no fission on sun?

The Sun get it power by nuclear FUSION not by nuclear fission.


Is fussion or fission happening in the sun?

How is the sun an example of nuclear energy?

The sun's energy is produced by nuclear fusion (not fission) at the core of the sun.


What are benefits fission and fusion gives us?

Fission gives us electricity from nuclear power plants. Fusion gives us the sun


How sun generates energy?

By heat released from continuous nuclear fission and fusion process.


How does nuclear energy relate to the sun?

We derive electromagnetic energy from the nuclear fusion reactions on the sun. We also apply nuclear energy (fission) on earth to generate lots of thermal energy, which we use in a steam cycle to generate lots of electric power.


Did the energy that is stored in fossil fuels come from fission or fusion reactions from the sun?

Not fission. The sun's energy is produced by nuclear fusion, and that energy produced all the vegetation which turned into fossil fuel.


Nuclear fusion to nuclear fission?

Nuclear fusion is the phenomenon in which two lighter nuclei get fused to form heavier nucleus with the production of energy. Best example is SUN and hydrogen bomb. But nuclear fission of breaking heavier into lighter with the emission of energy. Example uranium-235. So atom bomb Nuclear fusion has clean energy but fission has hazard energy


What is the difference between the sun's energy and a nuclear power plant?

the sun is powered by fusion, the power plant by fission


What type of power does nuclear fission have?

Fusion power is the power generated by the nuclear fusion processes. Fusion power is a primary area of researc in plasma physics. For example, the sun is a natural fusion reactor.


What is the difference between nuclear fusion in the sun and nuclear fission in a power plant on earth?

Fusion and fission are opposing processes. In the sun, hydrogen atoms are fused together to form helium. On earth, the most commonly used element is uranium, which is split into smaller atoms.
