A Wonderleaf question

a real page from the book
Earth has seasons because our planet spins at a tilt as it travels around the sun. When your half of Earth leans sunward, sunlight hits more strongly and days last longer; when it leans away, the light arrives lower and spread out, bringing winter.
That same tilt means the two halves of Earth swap seasons. While one side is getting long bright afternoons, the other has shorter days. Around the equinox, neither half gets the advantage, and day and night come close to matching.
Tilt a ball toward a lamp and slowly walk it around, watching which side gets the strongest light.
Watercolour scenes, straight answers, about three minutes cover to cover.
