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's seasons are not caused by the differences in the distance from the Sun throughout the year (these differences are extremely small). The seasons are the result of the tilt of the Earth's axis. The Earth's axis is tilted from perpendicular to the plane of the ecliptic by 23.45.This tilting is what gives us the four seasons of the year-spring, summer, autumn (fall) and winter.Since the axis is tilted, different parts of the globe are oriented towards the Sun at different times of the year.he Earth's axis is tilted from perpendicular to the plane of the ecliptic by 23.45.
