| Term | Definition |
|---|---|
| Aurora | colored light display in Earth's atmosphere |
| Chromosphere | thin layer of gases, just above the photosphere, that glows reddish during an eclipse |
| convective zone | the region of the sun's interior in which energy is carried upward by circulation of matter |
| core | the layer of the sun where matter is converted into energy (nuclear fusion) |
| corona | the outermost layer of the sun's atmosphere, visible only during an eclipse |
| coronal loop | super-hot loops in the Sun's atmosphere that run between magnetic positive and negative sunspot pairs |
| coronal mass ejection | part of the corona that is thrown into space from the sun |
| geomagnetic storm | a sudden disturbance in Earth's magnetic field |
| ionosphere | layer of Earth's atmosphere where auroras exist |
| magnetosphere | the space around Earth that contains a magnetic field -- protects the Earth from the sun's solar wind |
| nuclear fusion | The process in which small atoms combine to form new, more massive atoms; process that releases energy and fuels stars |
| photosphere | the visible surface of the sun |
| prominence | a loop of relatively cool, incandescent gas that extends above the photosphere |
| radiative zone | the region of the sun's interior in which energy moves through waves or particles |
| solar flare | an explosive release of energy that comes from the sun |
| solar wind | flow of electrically-charged particles from the sun in to the rest of the solar system |
| sunspot | cooler areas of the sun that appear darker and have a strong magnetic field |
