Why does fusion occur in he sun's core but not in other layers?

Thermonuclear reactions only occur in the core of the star because that's where the heat and pressure is so great that it overcomes the forces between the atoms. The surface stars is relatively cool. The Sun is only around 10,000° F on its surface. well below the several million degrees required for fusion.

∙ 12y agoThe Sun's core is hotter, and at a higher pressure, than the outer layers. I assume there is a very small amount of fusion in the outer layers, but not enough to make a real difference.

Does hydrogen fusion occur in the corona?
No. Hydrogen fusion occurs in the star's core.
Hypothesize what will happen when the sun exhausts it's supply of hydrogen?
When a main sequence star, such as our sun, exhausts it's supply of Hydrogen, fusion of Hydrogen to Helium ceases in the core. This results in cooling of the core and therefore causes it to contract. As the core contracts, the layers surrounding the star gain kinetic energy until the fusion of Hydrogen is possible in the outer layers. As these layers undergo fusion, they increase in temperature dramatically. The outer layers expand due to heat, and the star becomes massive; the main sequence star has evolved into a red giant. Fusion of Hydrogen to Helium continues in the outer layers, whilst the fusion of heavier elements such as carbon occurs in the core.
What layer of the sun does fusion occur?
Nuclear fusion occurs in the solar core.
Where does the sun's nuclear fusion occur?

Where does the fusion reacion occur on the sun?

Does hydrogen fusion occur in the corona?
No. Hydrogen fusion occurs in the star's core.
Which part of the newborn star does fusion occur?
In all stars, the fusion only occurs in the inner core.

How does nuclear fusion occur in the sun's interior core?
High temp and pressure
What layer of the sun does fusion occur?
Nuclear fusion occurs in the solar core.
Where does hydrogen fusion occur when there is no hydrogen left in the core of a star?
If there is no hydrogen left at the core of star then hydrogen fusion cannot occur. What happens in the core of a star before that happens is that helium begins to fuse, and then the other elements going up the periodic table until carbon. And then if the star explodes into a supernova, traces of the higher elements are fused as well.
Does the layer of fire on the sun occur in the suns core?
There is no fire in the sun, that is a chemical process. The process in the core is thermonuclear fusion.
