Why do we have Night and Day?

At Night time, we can all nap, eat dinner, and take a hot shower. At day time we can all eat breakfast, eat lunch, go to school or work, and also have fun. So what’s the difference between day and night? The answer is day is light and night is dark. 

But how is day and night formed? It is formed by the sun because when it shines on our half of the Earth, its day time for us. But, when it shines on the other half of the Earth, its night time for us. The sun doesn’t move, it’s the Earth which rotates on its axis. It takes 24 hours for the Earth to rotate once. The moon doesn’t have its own light, it gets its light from the sun. The moon is actually very small. It’s only a quarter of Earth’s size. 

Many people think the moon causes day and night. Well, the moon has nothing to do with day and night. We only see the moon because the sun gleams on the moon. The moon does nothing but orbits Earth. 

Why is day and night so important to us? Its important because at day time we can keep fit, and do many other important things. Night time is time for a rest after an exhausting day! Also, without sun light nothing can grow, we’ll end up dying and so does every other living thing!
