| Question | Answer |
|---|---|
| core | forms hydrogen, which then releases energy, fusion |
| radiative zone | energy then gets produced by fusion |
| convection zone | radiative energy heats it up making it rise and sink. This makes convection cell |
| Atmosphere | Photosphere: light energy, chromshere; the bottom layer (only visible during solar eclipses) Corona; faint hola around sun (glasses 1,000,000 degrees c) |
| How does nuclear fusion power the Sun, and why does it release so much energy? | atoms combine both nuclei and hydrogen creating helium. A little bit of mass is there creating energy and heat. |
| Why is the Sun's core the only place where fusion can happen? | The temperature is high enough for its standards |
| How does energy move outward from the Sun's core to space | It moves through all the different layers by the heat and hot gas |
| What is the difference between the radiative zone and the convection zone | |
| Why are the Sun's layers important for understanding how light and heat reach Earth | So we then know the dangers and time frame |
| How can changes in solar activity affect the amount of energy released by the Sun? | |
| What are sunspots. and what do they tell scientists about activity on the Sun? | Cold areas on the Sun that lose energy. This shows that the Sun is losing some of it's energy |
| What is solar wind, and how does it travel through space? | The Sun is so hot it produces electric particles. It travels through space through high speed |
| Why doesn't solar wind affect Earth in the same way it affects unprotected space | because the magnetic field blocks it |
| In what ways is our sun similar to other stars, and in what ways is it important to us | The Sun produces energy like all of the other stars. Solarwinds protect us from objects in space |
| What is the difference between a star's apparent brightness and absolute brightness | |
| Why can a star look dim from Earth even if it actually gives off a lot of energy | It is very far away |
| How does a star's color help scientists estimate its surface temp | |
| Which stars are hotter: blue stars or red stars, and why | Blue because it reflects the heat/energy |
| How can scientists use temperature an energy output together to estimate a star's size | |
| What is the interstellar medium, and why is it important in space | |
| How can the material in a region of space give clues about what happened there in the past | |
| What major steps happen as a nebula becomes a star | |
| why is the Sun said to be in the equilibrium right now | gravity and fusion cancel eachother out |
| What happens to stars after equilibrium ends, and hows is the future of a massive star different from the future of the sun |
