complete the sentences using the words: fusion, energy, helium, hydrogen, waves.\n1. in the suns core…

Brief Explanations:

1. In the Sun's core, hydrogen atoms undergo nuclear - fusion to form helium. This is a well - known process in solar physics.
2. The fusion process releases a large amount of energy in the form of electromagnetic radiation.
3. The Sun emits energy in the form of electromagnetic waves which carry the energy from the Sun to other parts of the solar system. For the short - answer questions:
4. Nuclear fusion in the Sun is important because it is the source of the Sun's energy, powering its light and heat output which is essential for life on Earth and the functioning of the solar system.
5. The energy from the Sun reaches Earth in the form of electromagnetic radiation (including visible light, infrared, ultraviolet, etc.) which travels through the vacuum of space at the speed of light.
6. Electromagnetic waves are a form of energy that consists of oscillating electric and magnetic fields. The Sun's energy is emitted as electromagnetic waves across a wide range of the electromagnetic spectrum, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X - rays, and gamma rays.
