7. Orbit, tilt, and curvature of earth result in increasing variation
For animation go to:
Orbit, tilt, and curvature of earth result in increasing variation
in photoperiod throughout the year at higher latitudes.

8. Orbit Tilt Albedo Distribution of light on earth affected by:
Curvature
Orbit
Tilt
Albedo

9. Total reflection: Albedo = 1.0

10. Heat budget of earth: more radiation and heat produced at equator, more loss of heat at poles. Atmosphere and oceans move heat and keep each area from getting warmer or colder, respectively.
