Shadows change length throughout the year because the altitude of the Sun above the horizon changes. The altitude (height above the horizon) of the Sun changes as the Earth revolves around the Sun each year. This is due to Earth's axis being at an angle. In the Northern Hemisphere, the North Pole is pointing away from the Sun on the winter solstice (around Dec. 21) and for the Northern Hemisphere the Sun is at its lowest altitude and shadows will be the longest of the year. On summer solstice (June 21), the Sun is at its highest altitude and shadows are the shortest of the year. Janice VanCleave

Does the day lengths change throughout the year because of the years tilt?
yes
Do the day lengths change throughout the year because of the earths tilt?
Yes. We could write a lot more, but yes is the answer.
Does the day lengths change throughout the year because of the earths tilt?
Yes/more at the north/south hemisphere zones but almost constant at the equator.
Does day lengths change throughout the the year because of the earths tilt?
Yes/more at the north/south hemisphere zones but almost constant at the equator.
Why do shadow lengths change thoughout the year?
because the earth is "tilted" 23.5 degrees. So, when earth rotates around the sun, it is either tilted closer, or farther away from the sun. For example, in summer, earth is titled towards the sun, making shadows short. But in winter, earth is tilted farther from the sun. So shadows are longer. That is why shadows are longer or shorter during the year.
Why the lengths of daytime and nighttime change during year?
because

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.
Where do the lengths of daylight change the most over the year?
at places closer to the equator

How does the sun change throughout the year?
The position of the sun changes throughout the year due to the Earth's tilt, causing the sun's angle to vary, leading to different solar angles and lengths of daylight at different times of the year. This results in the changing seasons as the sun's position affects how much sunlight each hemisphere receives.
Why do shadows change over a year?
answ 2. Due to the travel of the earth around its (non-circular) path on the ecliptic; and the tilt of the Earth's axis, the path of the (say) tip of the flagpole will not repeat exactly until a year has passed. The path of the shadow of this 'flagpole gnomon' will describe a passage known as the Equation of Time.This you can look up in an encyclopedia or a search engine.
