What is the main source of energy of the sun?a)Nuclear fission of heav...
Explanation:
Source of Energy in the Sun:
The main source of energy in the sun is nuclear fusion, which involves the combination of lighter elements to form heavier ones. This process occurs in the sun's core where temperatures and pressures are extremely high.
Nuclear Fusion Process:
- In the sun's core, hydrogen nuclei (protons) collide and fuse to form helium nuclei.
- This fusion process releases a tremendous amount of energy in the form of gamma rays and neutrinos.
- The energy released from nuclear fusion is what powers the sun and enables it to shine brightly.
Advantages of Nuclear Fusion:
- Nuclear fusion is a clean and sustainable source of energy that does not produce greenhouse gases or radioactive waste.
- It is a highly efficient process that can generate large amounts of energy from small amounts of fuel.
- Scientists are researching ways to harness nuclear fusion on Earth as a potential source of renewable energy.
In conclusion, nuclear fusion of lighter elements in the sun, particularly hydrogen to helium, is the primary source of energy that enables the sun to emit light and heat.
