Document Summary

Distance of the sun. earths revolution around sun and its tilt, atmosphere filtering effect. Solar constant of 1400 w/m2 once sun rays get to earth. Everywhere has 12 hours of day and 12 hours of night. When sun sees both poles at same time. Equal amount of light hitting north and south. Sub solar point is the condition of the earth where sun is directly over head. Axis line is 23. 5* north of light. Sub solar point 23. 5* south of equator. Sub solar point is 23. 5* north of equator. Geometric positions are important because they control position of sub solar point and therefore angle of indication. Angle of incidence is important because energy from sun is diluted in low angle positions and less diluted in high angle positions. If no tilt than we would have hotter equator and colder poles. Sun degree is 26* during winter, 50* during spring, fall and 73* during summer solstice.
