Today, we went to the Museum of Natural History. I learned aout the Earth's history, dinosaurs, and human's history. The topic that I was most interested in, was Earth's history. Let's start from the very beginning of all these steps. First, there was a bigbang, which made solar systems, stars, planets, and meteorites 15 billion years ago. Next, the Earth was formed 4.6 billion years ago. The Earth seemed like a red and black, big ball, that period. It was because of the magma and the harden magma was together. Lastly, there came the continent; which was at first, very big. The very big continent was called, 'Pangaea'. However, as time passed, the continent began to divide, and finally made the 6 continents; Asia, Europe, Africa, North America, South America, Oceania. I learned a lot about Earth's history, dinosaurs, and human's history, but I also learned a lot that now, it's a lot more safe than long ago.
