hydrogen and helium in our current sun:An analysis of its composition based on its mass establishes that it contains 71% Hydrogen, 27% Helium, and 2% of other heavier elements.
locations of nuclear fusion:Hydrogen nuclei fuse to form helium, releasing in the process a large amount of energy in the form of electromagnetic radiation, which reaches the earth's surface and which we perceive as light and heat.
convection of the Sun:Convection sprouts naturally in the atmosphere. On a warm, sunny day, the sun heats the surface of the Earth. This heat is spread to the layer of air immediately adjacent to the surface by molecular diffusion and turbulence, as well as by radiation.
Radiation of Sun: All energy from the Sun that enters the Earth arrives as solar radiation. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
