Sent 4: This energy can be released and used to do work.
Sent 5: This happens in nuclear power plants where they split apart the nucleus of an atom.
Sent 6: This splitting apart is called nuclear fission.
Sent 7: Another type of nuclear energy happens in the Sun.
Sent 8: Here the atoms nuclei are not split apart.
Sent 9: Instead, the nuclei of the atoms are fused, or joined together.
Sent 10: This process is called nuclear fusion.
Sent 11: Some of the suns energy travels to Earth.
Sent 12: This energy from nuclear fusion warms the planet and provides the energy for photosynthesis.
Question: What type of nuclear energy process occurs in the sun? (A) Fusion (B) Nuclear fission (C) kinetic energy process (D) Nuclear fusion (E) Heat conversion (F) Fission (G) The splitting of atoms (H) The joining of atoms nuclei.
answer:
A, D, H.
