Question

1. the suns energy comes from ____.

○ intense heat
○ nuclear fission
○ nuclear fusion
○ radioactive decay

Explanation:

The Sun generates energy by fusing hydrogen nuclei into helium in its core, a process that releases massive amounts of energy. Intense heat is a result of this energy, not the source. Nuclear fission (splitting atoms) and radioactive decay do not produce the Sun's primary energy.

Answer:

nuclear fusion
