Understand How Day Turns into Night

Every day, we have day and night. 

But how does day turn into night?

The Earth orbits (goes around) the Sun.

As the Earth is orbiting the Sun, it also spins on its own axis. This means it spins on an imaginary line.

It takes 24 hours, which is one day, for the Earth to make one full rotation.

While it is rotating, some parts of Earth will face the Sun. On these parts of Earth, it will be day. 

The countries and places on the other side of Earth won’t be able to get any sunlight so it’ll be dark and night in those places.

When it is night for some parts of Earth (the world), it’ll be daytime in other parts. 

For example, when the United Kingdom is facing the Sun, it’s daytime for people living in the UK. People living on the other side of the world, like in Australia, will be in darkness and it’ll be night.

Once the part of Earth where Australia is located rotates to face the Sun, the parts where the UK is will rotate away from the Sun.

As it takes the Earth 24 hours to do one full rotation, one day on Earth is 24 hours long.

In this activity, you’ll be answering questions about day and night. Good luck.
