The Earth is tilted, and as it moves around the Sun, different parts of the planet get more sunlight. When a place gets more sunlight, it's summer. When it gets less, it's winter. Imagine spinning a ball with a light on one side, some parts are in shadow, others are bright.
Examples
- In the Northern Hemisphere, it's summer when we point toward the Sun and winter when we turn away.
- Imagine being on a spinning ball, sometimes you're facing the light, sometimes in shadow.
- Your friend in Australia might be playing outside in summer while you are wearing a coat.
