How do the sun and moon relate to the four seasons?

The sun and moon play crucial roles in the four seasons primarily through their positions and movements. The Earth's tilt on its axis causes varying sunlight exposure, leading to seasonal changes as it orbits the sun. While the sun's position determines the intensity and duration of daylight, the moon influences tides and can affect weather patterns. Together, these celestial bodies create the cyclical nature of the seasons, impacting ecosystems and human activities.
