The Mystery of the Center of the Earth. The appearance of the earth, which can be seen by human beings, is the vast land and sea; towering mountains; The vast desert....When faced with the landscape of the earth, it is natural for people to ask, "What is the interior of the earth like?"
In order to solve this problem, scientists can be said to have exhausted all means. The most direct way is to drill a hole. However, it soon became clear that drilling was time-consuming and labor-intensive, and that it was impossible to drill 11,058 meters below the surface.
You must know that the radius of the earth is 6,371 kilometers, and 1 meter is not even a layer of skin compared to the radius of the earth. Later, it occurred to someone that the **wave was coming from the depths of the earth. When a wave hits different substances such as rocks and molten lava, the way and the way it travels changes change.
Therefore, according to this method, people have explored the structural level of the earth.
First, the outermost layer is the earth's crust. It is like a layer of the earth's crust, and the thickness of this shell is not the same, and secondly, the middle layer is the mantle. The Earth's mantle is 2,900 kilometers thick and is made up of hot magma, like a pot of hot thick porridge.
Finally, there is the Earth's core layer, the core. The Earth's core is composed of heavy metal elements such as iron and nickel, and its maximum internal temperature is 5000.
The study of the internal structure of the earth has only begun, and the mystery of the center of the earth is still waiting for mankind to solve.
