Today I went to museum of national history. We can know this museum is telling the nature¡¯s history So the in museum there is a Dinosaurs and solar system. What is the solar system by the gravity of the sun revolve around the sun as the Earth and other planets as celestial system made​​. The solar system¡¯s planet times are Mercury, Venus, Earth, Mar, Jupiter, Saturn, Uranus and Neptune. How about pluto?

It become weed out from the solar system because. The pluto is too small, inclined and it is too oval So it is not a planet anymore.

Then how did the Earth birth? The Earth born with a crash and crash then it became a big circle land. And also it have a gravity. So it pull the gas and some other thing. so it made a atmosphere then no more meteorite crashed. Then the plants can grow so the air envelope. Then the creatures lives. At the first time the continents were connected as one piece this is called pangaea this is a birth of the earth.

After I greet the museum of natural history. I can know more about the natural and I think we have to protect it.
