Seasons happen because Earth is tilted. Imagine Earth like a spinning top, it’s not straight, it’s tilted at an angle. When one side of the Earth faces the Sun more directly, that part gets warmer and has summer. The other side gets less sunlight, so it's cooler and has winter. In the Southern Hemisphere, people experience opposite seasons because they're on the other side of the tilt. So when it’s summer in the North, it’s winter in the South, and vice versa.
Examples
- When it's summer in New York, it's winter in Sydney, because they're on opposite sides of the Earth.
- A tilted Earth is like a lopsided merry-go-round, where one side gets more fun (sunlight) while the other has less.
- The seasons are like a game of hide and seek with the Sun. One hemisphere hides, the other sees it clearly.
