What are day and night cycles?

Day and night cycles are when the Earth turns, making parts of it face the Sun or turn away from it.

Imagine you're sitting on a spinning chair in your living room. When you face the lamp, it’s daytime, bright and light. When you spin around so your back is to the lamp, it’s nighttime, dark and quiet. That’s what happens with Earth and the Sun!

The Earth is like a big spinning top. It takes about 24 hours to make one full turn. As it spins:

• The part of Earth facing the Sun gets sunlight, so it's daytime there.
• The part turned away from the Sun doesn’t get sunlight, so it’s nighttime there.

You can see this if you watch a clock or your phone’s time, when it shows morning, that means your part of Earth is facing the Sun again!

Day and night cycles help us know when to wake up, play outside, or go to bed. It's like having a friendly friend (the Earth) who spins around every day so we can have both sunlight and darkness!
