Why Are There Seasons?

The video explains why Earth has four seasons due to its axial tilt. A long time ago, a massive impact tilted Earth, causing it to lean slightly. As Earth orbits the sun, different parts receive varying sunlight, leading to seasonal changes. When a hemisphere tilts toward the sun, it experiences summer; when it tilts away, it's winter. Spring and autumn occur in between. Seasons vary globally; when it's summer in the Northern Hemisphere, it's winter in the Southern Hemisphere, and vice versa.
