Document Summary
* to have chemistry, electrons need to be bound to atoms; in the sun, no atoms are bound to atoms (everything is ionized because it"s so hot) the dynamic sun. Convective zone heated from below, losing energy when it gets to surface (photosphere), goes back inward: granulation of the photosphere, each granule is about the size of texas and lasts for only 10-20 min before fading away. Solar prominence composed of hot gas trapped in magnetic fields extending from one sunspot to another. The heating of the corona the corona is heated by energy outflowing from the sun"s interior not as heat but as magnetic energy. 16. solar activity peaks roughly every 11 years solar flare. 17. a solar flare is a violet outburst that lasts in an hour or less. 18. it radiates x-ray, ultraviolet and visible radiation, plus streams of high-energy protons and electrons.
