The tilt of the Earth's axis, and it's elliptical orbit around the sun. We only have 24 hours in a day, so if the nights become longer, the days have to become shorter.
Seriously, it's all due to the Earth orbiting the sun in an elliptical pattern and the axis tilt, which always stays on the same plane. At the winter equinox, the days begin to get longer, until the summer equinox, when the days begin to shorten again. Note that in the winter, the sun sits much lower in the sky than during the summer, at least in the northern hemisphere. It's reversed for the Southern Hemisphere, as are the seasons. Hard to imagine summer for December, and snow in July, but that's how it is below the equator.

Why does the position of Saturn in the night sky change throughout the year?
Because Saturn revolves around the Sun and takes 29 years to do so.
Where does the length of day remain the same throughout the year?
never remains the same because of the worlds axis

Which date in year does the day and night equal?
When the day and night are equal it is called the equinox (means literately equal night). It happens twice a year. Once in the sping called the vernal equinox which occurs on the March,20 or 21 each year. Once in the autumn or fall called the autumnal equinox which happens September, 21 - 22each year.
Where on Earth are day and night of equal length throughout the year?
Day and night are of equal length throughout the year at the equator.
Why do day and night change length throughout the year?
Because of the amount of sunlight changing from the earth being on its axis
Does the days length change throughout the year because of earths tilt?
yes
Why do day and night change throughout the year?
Because of the amount of sunlight changing from the earth being on its axis
What would happen to Earth's climate if the tilt was 0º?
The two main factors would be that the seasons would not exist and the length of daylight and night time hours would not vary throughout the year at any given latitude. That the climate of any given latitude would change is inevitable with less variation throughout the year. The extent of the change is almost impossible to predict
Do you see the same stars when you look out at night?
The Earth's axis always changes so you will see some stars one night but they change throughout the year
How earths distance from the sun change throughout the year?

Why the length varies throughout the year?
Because of the rotation of the Earth.
What is the length of night on the desert?
The length of day and night depend upon the season of the year and the latitude of the desert. Over a year it averages 12 hours of day and 12 hours of night.
In which part of earth the day length is the same throughout the year?
The equator.
What determines the length of night on earth?
Depends on where you are (latitude) and the time of year.
