Why Do We Have ‘Seasons’ and How Are They Connected to Earth's Orbit?

Earth has seasons because it spins around the Sun while also being tilted on its axis, like a wobbly top that never stops spinning.

Imagine Earth is a giant ball that takes about 365 days to go all the way around the Sun. But instead of standing straight up, Earth is tilted, like when you lean back in your chair. This tilt means different parts of Earth get more sunlight at different times of the year.

When one part of Earth is tilted toward the Sun, it gets more direct sunlight and feels warmer, that's summer! The opposite side, tilted away from the Sun, gets less light and feels cooler, that's winter.

As Earth keeps moving around the Sun, the tilt causes the seasons to change in a cycle: summer, fall (autumn), winter, and spring.

It’s like having a magical flashlight, sometimes you’re right under it, getting all the light, and sometimes you're on the other side, getting just a little glow. That's how seasons happen!
