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.
It's a Matter of Tilt. The biggest reason for the seasons is that Earth's axis is tilted relative to its orbital plane. It may be that way because of a large impact in our planet's history that could be responsible for the creation of our Moon. The infant Earth was smacked pretty heavily by a Mars-sized impactor.
