These are one of the most interesting rural architectural styles in France, with many examples still in existence in north-east Aquitaine. Originally the pigeonniers were used for breeding and raising pigeons for food to the owners. Their characteristics typically include:
Thatâs logical, but not the case, for Earth. Instead, Earth has seasons because our planetâs axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane â the plane of Earthâs orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.
This Earthâs rotation around the Sun, or the precession of the Sun through the equinoxes, is the reason a year lasts approximately 365.2 days. It is also for this reason that every four years, an extra day is required (a February 29th during every Leap Year).
