None.
Nuclear fusion takes place in the core of the sun.
Fusion takes place in the core, where the temperature and pressure are much higher, which is necessary for fusion.
Nuclear fusion is the type of nuclear reaction that occurs in stars. Older stars with a collapsing center can exceed a temperature of one hundred million Kelvin.
Fusion
nuclear fusion
In nuclear fusion reaction two nuclei are combined by providing the energy.
I could answer is the question was more specific.
Nuclear fusion naturally takes place in the core of stars, where high temperatures and pressures allow hydrogen atoms to combine and release energy.
it only takes place at high temperature
Nuclear fusion takes place under conditions of extreme temperature and pressure, such as those found in the core of stars like the Sun. These conditions are necessary to overcome the electrostatic repulsion between positively charged atomic nuclei and fuse them together to release energy.
The central region of the sun is called the core.
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
