| A | B |
|---|
| Solar Wind | clouds of ionized charged particles moving out into space in all directions |
| auroras | formed as solar particles arrive at the earths atmosphere, only occur at N/S pole(higher latitudes) |
| magnetosphere | earth's gravity pull that holds our atmosphere in |
| wave length | distance of wave (over and back |
| wave heigth | distance between up/down, measurement starting position and go up |
| wave frequency | how many waves/#of times per second |
| wave period | how long it takes to complete the wave (one=up/down) |
| wave oscillating motion | repeating movement (back/forth) |
| insolations | incoming solar radiation |
| subsolar point | only point that is under the sun perpindiculaly - reaches the horizontal plane. Point at which sun is at the highest point |
| perihelion | closest position to the sun |
| aphelion | farthest position from the sun |
| fusion | hydrogen nuclei forced together under tremendous temp and pressure in the Sun's interior |
| solar constant | insolation at the top of the atmosphere |
| sun's altitude | angel between the sun and the horizon |
| sun's declination | latitude of the subsolar point |
| circle of illumination | the boundary that divides daylight/darkness |
| ecliptic plane | touching all points of the earth's orbit |
| winter solstice | 12/21 or 22, circle of illumination excludes the N. Pole |
| Vernal equinox | March 20/21 - circle of illumination passes thru both poles |
| Summer Solstice | 6/21, circle of illumination includes the N pole |
| Autumnal Solstice | 9/21 or 22, cicle of illumination passes through both poles. all spots on earth have 12 hr day and 12 hour night |
| Season | changing position of the circle of illumination. Seasonal variation of the sun's position above the horizon, changing daylengths during the year. |
| tile of earth | 23.5 degrees |
| influence of seasons | declination/tilt of the earth, rotation, revolution, spherical effects, axial parallelis |
| 5 reasons for seasons | tilt of axis, rotation of axis, revolution, sphericity, axial parallelism |
| names of wavelengths (short to long) | gamma, x-ray, ultra violet, visible, infrared, microwave, radio |
| ROYGBV | Red, Orange, Yellow, Green, Blue, Violet |
| Gamma ray | short |
| Radio Waves | big/long |
| Electromagnetic Spectrum | electon magnet range, as you come down the spectrum the wave lengths get bigger. |
| Infrared | below red |
