3Altitude – angle of elevation above the horizon Zenith – directly overheadCelestial Sphere - large sphere surrounding the earth, used to keep references to where celestial bodies lie in the sky.
4Tropic Of Cancer – 23 ½ o NTropic of Capricorn - 23 ½ o SSolar Noon - the time of highest sun altitude
5Insolation – Incoming Solar Radiation (energy we get from the sun) Sun’s Duration – length of time the sun is out = daylight hoursSun’s intensity – higher the sun angle, more direct rays = more energy from sun and higher temperatures.
