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 axis of the Earth is tilted, which means that in summer we (in the UK) are leaning towards the Sun. As we travel around the Sun, we begin to tilt away and it becomes winter. Have a look at this clip to see how the Earth's tilt changes the seasons. This is why when we have winter, Australia has summer. Imagine having Christmas dinner on the beach! But not all countries have seasons. Countries near to the equator - the line which goes round the middle of the earth - have very mild seasons. The weather stays almost the same temperature all the year round.
