We live on the earth, but we may not be familiar with it. The Earth is one of the nine planets in the solar system. It is shaped like a ball but is slightly flatter. It is not exactly the same shape as a globe. The radius of the earth is more than 6,000 kilometers, and the circumference is about 40,000 kilometers. It takes one day and one night to rotate once on its axis, and one year to revolve around the sun. The earth is a satellite of the sun and the moon is a satellite of the earth. That is to say, the earth revolves around the sun and the moon revolves around the earth. There are oceans, land, people, animals, and plants on the earth. It is the richest planet in the universe.
Reader comments
Moreover, this book also taught me a lot of knowledge, such as the reason for the rotation of the earth. This reminds me of the "One Hundred Thousand Whys" we watched when we were children. It is also a popular science style that can stimulate children's curiosity and desire to explore. I think this kind of books are very helpful for children's growth and allow them to learn a lot of knowledge in a relaxed and enjoyable atmosphere.
Real and objective, multi-dimensional description structure is clear,
Rich content
I like knowledge-based books, memories of my childhood, and old people re-learning.
