Document Summary
How is the absorption line spectrum produced: produced by atoms and ions absorbing speci c wavelengths of underlying 5800 kalvin continuum, close up, the sun has a granulated appearance. Cooler areas are darker (property of blackbodies/stefan boltzmann law) Due to convection: hotter gas rises, and the cooler gas falls. Chromosphere: it appears pink - due to the combined color emission from the balmer series (h-alpha. Solar ares (range from gentle to explosive ejections of material from the sun: solar cycle of full solar activity to minimal/no activity takes approx.
