Explanation:

Solar flare is an eruption when sunspot - loop connections occur (f). Core is the sun's center (h). Chromosphere has a reddish glow (b). Sunspot is a cooler gas area on the sun's surface (d). Corona looks like a halo during eclipse (c). Nuclear fusion is hydrogen - to - helium joining (j). Photosphere gives off visible light (a). Solar wind is a charged - particle stream from corona (g). Prominence are reddish gas loops linking sunspot regions (e). Radiation zone transfers energy by electromagnetic radiation (k). Convection zone is the outermost layer of the sun's interior (i).
