Answer :
Final answer:
The Sun generates energy through nuclear fusion reactions, primarily converting hydrogen to helium, which sustains its brightness over billions of years.
Explanation:
The Sun's Energy Production:
The Sun produces energy through nuclear fusion reactions in its core, primarily the proton-proton chain converting hydrogen to helium. This process releases vast amounts of energy, which is transmitted through convection and radiation, sustaining the Sun's brightness.
Key Points:
- Fusion Reactions: Proton-proton chain converts hydrogen to helium.
- Energy Transmission: Convection and radiation carry energy outward.
- Duration: Sun has been producing energy for billions of years.
