| Prominence | A loop of gas connecting sunspots.
🗑
|

| Solar flare | An explosion of hydrogen gas from the sun's surface that occurs when sunspot regions suddenly connect.
🗑
|

| How is energy produced in the sun's core? | Through nuclear fusion, turning hydrogen into helium.
🗑
|

| Name the three layers of the sun's atmosphere | Photosphere, Chromosphere and Corona.
🗑
|
||||
| Name three features found on the surface of the sun. | Sunspots, prominences, and solar flares.
🗑
|
||||
| Why do sun spots look darker than the rest of the sun's photosphere? | Sunspots are areas of cooler gas, and cooler gas gives off less light.
🗑
|
||||
| How do sunspots change over time? | By the changes in climate on earth.
🗑
|
||||
| What is a solar flare and how can it effect us? | Solar flares occur when the gas on the surface of the sun explodes and connects sun spot regions. How it effects us is that when a solar flare occurs it gives off a lot of solar wind, which can effect us at the poles more than anywhere else by creating m
