**Earth is tilted**, like a spinning top that leans a little. It stays tilted in the same direction as it travels around the Sun.

- When the **north leans toward the Sun**, sunlight hits it more directly, and the days are longer. That makes **summer**.
- Six months later, the **north leans away from the Sun**. Sunlight hits it at more of a slant, and the days are shorter. That makes **winter**.

The south gets the opposite seasons: when it’s summer in the north, it’s winter in the south. 🌍

It’s the **tilt**, not how close Earth is to the Sun, that causes the seasons.
