How Does Earth's Tilt 1: The Reason for the Seasons Work?

Earth’s tilt is like a spinning top that leans, and it’s why we have seasons, spring, summer, fall, and winter.

Imagine Earth as a big, round ball that spins around the Sun, just like you spin around your friend during playtime. But Earth isn’t perfectly upright, it’s tilted at an angle of about 23 degrees, like when you lean back in your chair.

As Earth goes around the Sun, this tilt means different parts of Earth get more sunlight at different times of the year. When the Northern part of Earth is tilted toward the Sun, it gets more sunlight and has summer. At the same time, the Southern part is tilted away and gets less sunlight, that’s winter.

When Earth keeps spinning, the tilt changes direction. Soon enough, the Southern part gets more sunlight, summer there, and the Northern part gets winter. It's like switching places with your friend in the playtime game, now you are getting more light, and they're in the shade!

This tilt doesn’t change, it’s always there, just like your chair always leans the same way. That’s why we have seasons every year!
