Question

15 multiple choice 5 points light and other forms of electromagnetic radiation are given off by stars using energy released during nuclear fusion conduction convection radioactive decay

Explanation:

Nuclear fusion occurs in stars. In this process, light - weight atomic nuclei combine to form heavier nuclei. A large amount of energy is released during this combination. This energy is radiated as light and other forms of electromagnetic radiation.
Conduction is the transfer of heat through a material without the bulk movement of the material itself. It is not the source of energy for stars to emit electromagnetic radiation.
Convection is the transfer of heat through the bulk movement of a fluid (liquid or gas). It is a mode of heat transfer within a star but not the source of the energy that is radiated as electromagnetic radiation.
Radioactive decay is a process in which an unstable atomic nucleus loses energy by emitting radiation. While radioactive decay occurs in some objects (like certain rocks on Earth), it is not the dominant process in stars for emitting light and electromagnetic radiation.

Answer:

nuclear fusion
