Here's why:
* Earth's Orbit: The Earth takes approximately 365.25 days to complete one full orbit around the Sun. This is what we call a year.
* Seasons: Seasons are caused by the tilt of Earth's axis (23.5 degrees). As Earth orbits the Sun, different parts of the planet receive varying amounts of direct sunlight due to this tilt. This leads to the changes in weather patterns we experience as seasons.
In summary: Seasons are a result of Earth's tilt and its position in its orbit around the Sun, not the completion of a full orbit itself.
