Stories about the Earth 20, Stories about the Earth

The German philosopher Immanuel Kant proposed the "nebula theory" in 1755. Based on the astronomical observations of the time, he believed that there were primitive scattered particles of matter in the universe, which produced a rotational motion around the center and gradually concentrated in a plane, and finally the central matter formed the sun, and the matter on the equatorial plane formed planets such as the earth and other small celestial bodies. This "nebula theory" later gradually formed a school of thought on the origin of the solar system.

The formation of the earth, according to the nebula theory, the earth's protostars were about 500 times heavier than now, and the diameter was about 2,000 times that of the present. When the sun shrinks to the interior to react, the sun heats up, emits light, and radiates a large number of particles, which sweep to the earth's surface and "drive away" the light matter on the earth's surface. So the earth is left with those dense, basically solid matter.

There are also some hypotheses, and there is some truth to them. For example, some people think that the earth is thrown out of the sun; Some believe that one of the twin stars of the Sun became the Earth after it became fragments. These hypotheses are not accepted by everyone like the nebula theory.

Am I old? How I can't understand this question. The story about the Q of the earth? She's right at our feet. Find a green meadow, lie on it in a large shape, look at the deep blue sky, and take a few deep breaths of air. You'll be a part of her.

In this, I sympathize with Africans the most, because the white slave traders trade with blacks. Because of this, we want to stop the slave traders and give the black people a warm home.

Because the book was written in 1932, the Earth was a completely different place: the air was much cleaner than it was then, the ozone layer.

There are no hollows either. But now, the overexploitation of mankind has engaged in a miasma of smoke on the earth. Also, I'm very grateful for a **. It is said that the Chinese have not been able to catch up with the pace of the world for a while, but I believe that they will one day catch up with the Westerners, and the Westerners will never be able to compete with them.

This book is very interesting, and it tells me a lot of stories about the earth. There is the position of the earth in the universe, the age of the earth, the position of the various continents, the formation of the climate and various natural landscapes, the origin of living things, and so on. A lot of stories can be seen and felt in life.

This book made me realize the wonder and mystery of nature, in fact, in addition to the book on the stool, there are many miracles in life that human beings have not discovered, as long as we observe carefully and think carefully, we will definitely find it.

The main content of the story of the birth of the earth and the feeling after reading.

First, from the molten core to the outermost atmosphere, our planet operates as a vast interconnected system. At first glance, there may seem to be a big difference in terms of topography and climate, as do others like **, volcanoes, glaciers and monsoons, but in fact, they are closely related to each other.

Second, the vibrant geological activity on our planet is an indispensable factor in the origin and evolutionary development of life. The author expounds on these ideas through vivid descriptions, memorable ideas, and the latest scientific ideas and presentations.

Through its depictions of the remarkable forces that shape and shape the ever-changing planet, Tales of the Earth gives us a new perspective on the planet and our place in its evolution.
