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.
Summary: 1  The Earth is heated by the flux of energy it receives from the Sun, and cools down by emitting infrared radiation to space. 2  The rates of incoming and outgoing energy have to be in balance if the Earth temperature is to remain constant. The eccentricity of Earth's orbit causes the distance to the Sun to slightly change (being largest in July and shortest in January). The seasons, however, are caused by the tilt of the axis of rotation of the Earth.
