Have you ever went to the Nature history museum? I went there today morning. First, I will tell you about how the earth created. 4.6 billion years ago, there was the big-bang so the earth was made of gas and dusts. But few times later, the earth changed some fire and waters. And because of the earthquake, our earth have mountains, lands, and the sea. Second, solar system. In the space, there were 9 planets but now there are only 8 planets because the last planet, pluto was out of orbit so we aren't say pluto is the planet. So now in the universe, there are 8 planets. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Last, earth's structure. Inside the earth, There are innercore, core, outercore, mental and crust.

Today, I was knew about many things like this and I like earth because in the earth, there are continets, oxygens, seas, and beautiful nature. I think we are very lucky ro live in the earth and I want to studt about earth some more information. Thankyou.
