Q: Sun energy is generated by–
  • A. Fusion Process
  • B. Fission Process
  • C. Combustion Process
  • D. None of these
Correct Answer: Option A - The sun generates energy in its core via a process called nuclear fusion. During nuclear fusion, the sun's extremely high pressure and hot temperature cause hydrogen atoms to come apart and their nuclei (the central cores of the atoms) to fuse or combine. Four hydrogen nuclei fuse to become one helium atom. But the helium atom weighs less than the four nuclei that combined to form it. Some matter is lost during nuclear fusion. The lost matter is emitted into space as radiant energy.
