The Earth spinning around its own axis is what makes day and night happen.
Imagine you're sitting on a merry-go-round at the park. When it spins, sometimes you face the sun, that’s daytime. Sometimes you turn away from the sun, that’s nighttime. The Earth is like that merry-go-round, but much bigger!
How It Works
The Earth takes about 24 hours to make one full spin. That’s why we have a day and a night every day.
Think of it this way: if you're on the part of the Earth facing the sun, you see light, that's your day. When the Earth turns, you move to the side that's in shadow, that's your night.
It’s like being on a giant spinning ball, and one half is lit up while the other is dark. You just keep moving around with it!
So, every time the Earth spins, you get a new day, just like when you ride the merry-go-round again!
