* Fire is a chemical reaction involving combustion, where fuel reacts with oxygen to produce heat and light. The sun's energy comes from nuclear fusion, not chemical reactions.
* Lava is molten rock found on Earth. The sun is a giant ball of plasma, which is a superheated gas where electrons have been stripped from atoms, creating a sea of charged particles.
The Sun's Energy Source:
The sun's energy comes from nuclear fusion. In its core, hydrogen atoms are forced together under immense pressure and heat, fusing to form helium. This process releases an enormous amount of energy, which we experience as sunlight and heat.
