What were the early ideas of how the Sun shines? Why were these ideas incorrect? Why does the Sun shine? - Answer-Chemical burning was what humans thought made the sun shine. However, if this was true- the sun would be like a campfire that would need a fuel source and to be "fed" periodically. The Sun shines due to nuclear fusion Be able to name the Sun's layers from inside to outside and be able to know the importance of each layer (e.g. what type of light does the chromosphere emit?) -...
