The primary reason for the seasons in the Northern Hemisphere is not the changing distance between Earth and the Sun. The evidence that contradicts this idea includes the fact that Earth's distance from the Sun only varies by about 3%, the observation that Earth is actually closest to the Sun in January, and the presence of opposite seasons in the two hemispheres.
The primary reason for the seasons in the Northern Hemisphere is not the changing distance between Earth and the Sun. The evidence that contradicts this idea includes:
The fact that Earth's distance from the Sun only varies by about 3%, which is not enough to cause significant variations in the Sun's heating.
The observation that Earth is actually closest to the Sun in January, when the Northern Hemisphere experiences winter.
The presence of opposite seasons in the two hemispheres, which cannot be explained by distance alone.
