We live on Earth. It's (we) home. But how much do you know about ? Let me tell you something about our Earth.
The Earth is like a huge ball. Like other seven planets, the Earth is (run) around the Sun. It's the third nearest one to the Sun. It (take) the Earth a year to run around the Sun. At the same time, the Earth is going around itself. If you are in space, you can see (lot) of white clouds over the surface of the Earth. Through the clouds, you can see the blue colour of the (ocean), and the brown colour of the land. About 70% of the Earth (be) covered with water.
Why do we have day and night? When the half the Earth is facing the Sun, it's daytime. As the Earth (turn), and this half is away from the Sun, night is coming. And it's daytime for the other half.
