Seasons 3D

The Earth is tilted on its orbit. This causes an unequal amount of sunshine to fall in different parts of the planet during the course of a year, and this is responsible for the seasons. You can use this animation  to illustrate the  variations in the length of daylight,  and the seasons,  in the northern hemisphere.

The circles represented are:

  1. Arctic circle (66°N)
  2. 45°N latitude (Seattle, Toronto, Milan)
  3. Equator
  4. Antarctic circle (66°S)

The animation is not drawn to scale for either sizes or distances. Nor are the relative speeds of rotation and revolution accurately represented.
