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.
The Earth is in the sun's path, so it stands in the way of and accepts its energy. How the sun's energy is used by the Earth depends on its axial tilt. At 23.5 degrees, the axial tilt allows the sun to cause four seasons. However, if it became slightly lower, there would be a summer and winter, but no spring or autumn.
