Explain three lines of evidence that indicate that the seasons in north america are not caused by the changing earth-sun distance as a result of earth's elliptical orbit around the sun.

1. Seasons happen because the axis of Earth is tilted at an angle of about 23.4 degrees

2. Seasons happen because different parts of Earth receive more solar energy than others.

3. The distance of our planet from the Sun has little effect on the onset of seasons. In fact, Earth is closest to the Sun, or at its Perihelion, around the Northern Hemisphere's winter solstice.
