Why doesn't the changing distance between the Earth and the Sun affect the seasons?

The changing distance between the Earth and the Sun does not significantly affect the seasons because the tilt of the Earth's axis is the primary driver of seasonal changes. The Earth's axial tilt of approximately 23.5 degrees causes different parts of the planet to receive varying amounts of sunlight throughout the year, leading to seasonal variations. While the Earth's orbit is elliptical and its distance from the Sun does change, this variation is minor compared to the impact of axial tilt on seasonal temperature and daylight.
