Question

Quizplus · Accepted Answer

Fusion reactions in the Sun only occur in the core, which is the central region where the temperature and pressure are high enough for hydrogen atoms to fuse into helium through the process of nuclear fusion. Other parts of the Sun, such as the radiation zone and convective zone, do not have the necessary conditions for fusion reactions to occur.
