Question

Nuclear fusion uses high temperatures, high pressure, and hydrogen gas to combine and release helium gas and energy. Where does this occur in the sun?

1) Core
2) Radiation zone
3) Convection zone
4) Photosphere

Answer 1

Nuclear fusion occurs in the core of the sun, where the conditions are right for hydrogen nuclei to combine into helium, thus releasing energy.

Step-by-step explanation:

Nuclear fusion is a process that powers the sun by converting hydrogen nuclei into helium, releasing a significant amount of energy. This process occurs under extremely high temperatures and pressures, which can only be found in the core of the sun. In the core, hydrogen atoms undergo a series of reactions, eventually forming helium and emitting energy, which then diffuses slowly to the sun's surface, with neutrinos escaping immediately.
