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 tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later.We are psychologically primed to detect differences. We detect hot and cold. Then we detect almost hot and almost cold. That gives the four seasons. The earth orbits the sun, completing one orbit every (approx) 365.25 days. But whilst it spins on its North-South axis (causing day and night) it also tilts slightly, causing the North Pole to 'lean' towards the sun for part of it's orbit, then the South Pole for the other part.
