One way in which fission differs from fusion is:

• Fission involves splitting of atomic nuclei, while fusion involves combining them.

• Fission occurs naturally in stars, while fusion is man-made.

• Fission requires extremely high temperatures, while fusion does not.

• Fission is the process that powers the sun, while fusion is used in nuclear reactors.
