Why does the sun shift its position along the horizon with the changing seasons?

The sun shifts its position along the horizon with the changing seasons due to the tilt of the Earth's axis and its orbit around the sun. As the Earth orbits, the tilt causes different parts of the planet to receive varying amounts of sunlight throughout the year. This results in the sun appearing higher in the sky during summer and lower during winter, leading to its changing position along the horizon at sunrise and sunset. Thus, the sun's path varies based on the season, directly influencing daylight hours and temperature.
