| The
Sun is the source of all our energy |
|
|
|
|
| Every second,
millions of protons in the Sun's
core collide with |
|||
| other protons
due to powerful pressures to produce helium |
|||
| nuclei in a fusion reaction that releases energy. |
|||
| Neutrons + protons Helium nucleus + energy |

| Without
the Sun’s heat and light, |
||
| life on Earth would not be possible. |
