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.

What is the length of day in night in the rainforest?
Well, darling, in the rainforest, the length of day and night is pretty much the same as anywhere else on Earth. It's roughly 12 hours of daylight and 12 hours of darkness, give or take a few minutes depending on the time of year. So, you can enjoy the lush greenery and exotic wildlife during the day, and then cozy up in your hammock under the stars at night.
Why does the position of Saturn in the night sky change throughout the year?
The position of Saturn in the night sky changes throughout the year due to the Earth's orbit around the Sun. As the Earth moves along its orbit, our perspective of Saturn from Earth changes, causing its position in the night sky to shift. This phenomenon is known as the apparent motion of the planets.
What is the causes a year on earth?
The rotation of the Earth on its axis causes day and night. The revolution of the Earth around the Sun causes the change in seasons. The tilt of the Earth's axis is responsible for the varying lengths of daylight throughout the year.
What is the day and night length for each season?
The length of day and night varies throughout the year due to the tilt of the Earth's axis. In general, during the spring and fall equinoxes, day and night are approximately equal at around 12 hours each. During the summer solstice, days are longer and nights are shorter, while during the winter solstice, nights are longer and days are shorter.
Where does the length of day remain the same throughout the year?
At the equator, the length of day remains relatively constant throughout the year, with approximately 12 hours of daylight and 12 hours of darkness. This is due to the tilt of the Earth's axis in relation to the sun, resulting in consistent day length.
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
Where on Earth are day and night of equal length throughout the year?
Day and night are of equal length at the equator, which is an imaginary line that circles the Earth halfway between the North and South Poles. This phenomenon occurs during the equinoxes, which happen around March 20-21 and September 22-23 each year.
Does the length of day and night stay the same during the year?
No, the length of day and night varies throughout the year due to the tilt of the Earth's axis as it orbits the sun. This results in the changing seasons and varying lengths of daylight and darkness.
Does the lenght of day and night change more at the equator or at the oles during the tear?
The length of day and night changes more at the poles than at the equator throughout the year. At the poles, there are periods of continuous daylight in the summer and continuous darkness in the winter, leading to extreme variations in day length. In contrast, the equator experiences relatively consistent day lengths of about 12 hours throughout the year, with only slight variations.
Why do day and night change throughout the year?
Because of the amount of sunlight changing from the earth being on its axis
What determines the length of night on earth?
The length of night on Earth is determined by the position of the Earth in relation to the sun as it rotates on its axis. The tilt of the Earth's axis and its orbit around the sun dictate the changing lengths of day and night throughout the year. Factors such as the time of year and location on Earth also influence the duration of night.
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
How earths distance from the sun change throughout the year?
how does earths distance from the sun change throughout the year
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.
Why the length varies throughout the year?
Because of the rotation of the Earth.
In which part of earth the day length is the same throughout the year?
The equator.
