Blaming the Seasons on Distance from the Sun
Students say summer happens because Earth is closer to the Sun and winter happens because Earth is farther away.
Quick check
Why students make it
A closer lamp feels warmer, so it seems natural to blame seasons on distance. This intuition ignores that Earth is only slightly closer or farther from the Sun during the year.
The rule done right
Seasons are caused mainly by Earth's axial tilt, not by its distance from the Sun. A hemisphere has summer when it tilts toward the Sun, which gives more direct sunlight and longer days.
