| hydrogen | | In a few Billion years our star will become a __________ |
| coronalmassejections | | Our Sun (and all active stars) emits ______________ |
| radiativezone | | the sun is larger than the Earth (T or F) |
| solar flare | | the crown, above the chromosphere, seen only during eclipses |
| auroras | | the only time we can see the chromosphere |
| sunspots | | flame like structures extending above the photosphere for short periods of time |
| eleven | | Our sun is made of 70% ______________ and 28% Helium |
| onehundredten | | This is between the core and convection zone. |
| core | | about how many times wider is the sun compared to the earth? |
| radiation | | sudden burst of electromagnetic energy and particles from a magnetic loop in an active region |
| granulation | | the color of our sun |
| photosphere | | the color sphere. Temps can reach 20,000 K |
| chromosphere | | a continuous flow of particles that blows past the earth |
| solarwind | | This protects us from some ultra-violet, and most x-rays and gamma rays |
