Although the distance between the Earth and Sun varies slightly throughout the path of Earth’s orbit, it has little impact on seasonal changes. What has the most impact on the seasonal changes? A.
The length of the Sun’s orbit around the Earth has the most impact on the variations in the amount of daylight and temperature that produce seasonal changes.

B.
Earth’s axis tilt changes direction as it orbits the Sun which has the most impact on the variations in the amount of daylight and temperature that produce seasonal changes.

C.
The alignment of the Moon, Earth, and Sun has the most impact on the variations in the amount of daylight and temperature that produce seasonal changes.

D.
Earth’s axis tilt and the relation of the poles to the Sun has the most impact on the variations in the amount of daylight and temperature that produce seasonal changes.
