You can use ** wave to effectively study the earth's core, because ** wave is an elastic wave, according to the different ways of propagation, it can be divided into transverse waves and longitudinal waves, through different material propagation, the speed is not the same, so it can be said that the core can be studied well.
-
Humans do not need to dig through the earth's crust to study the core of the earth's crust, and scientists mainly need to extract the materials in the earth's crust to conduct research.
-
Compute. Because all matter has certain laws, humans can study the earth's core through experiments and calculations.
-
The speed of the waves is affected by the properties of the material through which the waves pass, and the stiffness of the material affects the speed of these waves. The time it takes for certain waves to reach the meter after a measurement can indicate the specific properties of the material that these waves encounter. When a wave encounters layers with different compositions, it will change direction or velocity.
There are two types of waves: longitudinal or pressure waves and transverse or shear waves. Longitudinal waves can pass through both liquids and solids, whereas transverse waves can only pass through solids.
Longitudinal waves propagate at a faster rate, and the distance to the hypocenter can be estimated by measuring the time gap between their reach.

It's a complicated question, but you can understand it if you understand the principle of X-rays, and there are many similar ways to know the internal structure of the earth without digging through the earth's crust.
-
Study. Because the human brain is very intelligent, it can deduce the internal structure of the earth through the study of the earth.
-
Scientists can analyze the Earth's crust directly, but they rely on ** and magnetic analysis to study the Earth's interior. It is generally believed that the Earth's interior consists of several layers: the crust, mantle, and core.
Since the earth's crust is easily accessible, scientists are able to conduct experiments to determine its composition. For more distant mantles and cores, the opportunities for research are very limited. As a result, scientists rely primarily on ** waves as well as gravity analysis and magnetism.
Research research.

Humans have been digging for 10 years, but they have not yet dug through the earth, how do they know the internal structure of the earth?
-
We can't go any deeper than we can at the moment unless we have higher technology. The average radius of the Earth is about 12,756,000 meters, and the Earth's interior is made up of the Earth's crust, mantle, and core. A foreign country excavated the deepest 12,262 meters from 1993, which is the deepest depth of the earth detected so far.
The process also revealed the process of underground drilling into the Earth's core, which in any case was only a fraction of the depth 6,400 kilometers ago.
The drilling that has been explored so far is only in the crustal layer, each layer of the crust has a different thickness, with an average thickness of 100 km, working in the crustal layer, the drilling work changes the drill bit used for drilling because it has to face rocks of different hardness and the drilling is very slow. In addition, it is unable to cope with unexpected situations, which will make progress extremely slow.
Even if we want to pass through the crustal layer of the mantle layer of a large amount of magma, the ultra-high temperature can melt any metal, therefore, we humans need to use the current technology, we humans still have a certain challenge to this problem, even if we humans have passed through the above two layers, but it may be difficult to pass through the core of the earth, because there is a layer of liquid outside the core of the earth, but the more dangerous problem is that we humans do not know what these liquid-like substances are on the earth.
Under the liquid substance, there is a core of iron and nickel, and the hardness of the drill bit that we humans use is the strongest in the world, and he will also fight it out in this core with a thickness of 1216 thousand millimeters, because he will have to face a very big test, and in addition, the closer we are to the core of the earth, the higher the temperature of our earth's interior will be.
If you have other different ideas and views, you can share your personal views in the comment area below, if you like me, you can pay attention to it, and finally wish you all the best.

It can be detected by instrumentation and theoretical derivation. There are many theoretically deduced things that cannot be seen or touched, but they do exist, such as electricity, air, etc.

The composition of the Earth's core is analyzed by means of some analogy experiments or the elements contained in the earth's crust.

As we all know, we still don't fully understand what the interior of the earth or even the center of the earth looks like, and even if we have collected some data, it is very small compared to the huge earth system, and the biggest reason is that we have not been able to dig through the earth's crust yetSo why can't humans dig through the earth's crust? How to study the Earth's core? On the one hand, this is due to the complexity of the structure of the earth's crust, and on the other hand, because the current degree of scientific and technological development is limited.
However, judging from the current degree of scientific development, we can indirectly study the earth's crust through the characteristics of ** waves, groundwater, and magma from volcanic eruptions.
The earth is the common home of our human beings, it has given birth to thousands of creatures, but our understanding of the earth is not thorough, and there are two most important factors that hinder our study of the earth, first of all, the first point is that the internal structure of our earth is very complex, and secondly, because the current level of scientific and technological development of human society is still very limited, it is unrealistic to dissect the earth layer by layer.
The development of science and technology always requires a long process, it requires people to invest a lot of manpower and material resources to be possible, and the current level of scientific development is only a very shallow layer of the earth's crust to study, this layer of the earth's crust is very small compared with the entire crustal system. Therefore, we only have a preliminary understanding and study of the part of the earth's crust, and we need to make greater efforts to study the entire crustal system.
Everything in this world is very interconnected, and we should not always be stereotyped. Although the task of studying the earth's crust is daunting, I can get a general understanding of the material composition and structural characteristics of the earth's crust through the propagation characteristics of ** waves, magma from volcanic eruptions, and the propagation of groundwater and underground sounds, just as a smart scientist uses the propagation characteristics of ** waves to study the material composition and structural characteristics of the earth's interior.
-
Humans cannot dig through the earth's crust because the earth itself is a sphere that is unfathomable, and the earth's crust is the earth's crust, so it cannot be dug through. The study of the earth's crust can be done by extracting the material on the earth's crust.
-
Because the scientific and technological level of human beings cannot dig through such a thick crust, there is no way to study the earth's core, and the existing structure of the earth is speculated by human beings.
-
Because the current level of scientific and technological development of human beings has not yet reached the ability to dig through the earth's crust, the deeper it goes, the higher the technical requirements are required. First, according to the existing known **, further study the technology, and use science and technology to explore the mysteries of the earth's core.
-
This question has been given our definition a long time ago, so far, the deepest part of the earth excavated by humans is the carat drilling of the former Soviet Union, which is only 12 kilometers and only 1 1000 meters in diameter of the earth, to dig to the center of the earth, we need to dig another 500 meters such a distance, for the core of the earth, we can only rely on speculation, for example, ** waves and other data are used for physical reasoning, at present, scientists believe that the earth is divided into three parts, the crust, the mantle and the core of the earth.
Among them, the most mysterious is the Earth's core, which is a sphere with a radius of about 3,470 kilometers, twice the size of the Moon. According to the changes in the ** wave, scientists judge that the earth's core is also divided into nuclear and outer core. The density of the core is about 10 7 grams per cubic centimeter, the total mass is 18 8 trillion tons, relative to the total mass, about a quarter of the Earth's 31 5, and the average density of the Earth is about 5 5 grams per cubic centimeter, we can see that the Earth's core is composed of relatively heavy material.
We know that the earth has a magnetic field, however, we randomly pick up a stone from the ground, it is not magnetic, therefore, scientists believe that it is a magnetic field produced by the core of the earth. The reason why the earth's core generates a magnetic field is that it contains a large amount of heavy metals, such as iron and nickel, in the natural environment, there are also many such natural underground passages, but this natural underground passage is more due to the drying or transfer of underground rivers, which is formed with the change of the earth's crust.
Usually the depth is not very deep, in fact, the temperature of the Earth's core is very high, and the closer you are to the core, the higher the temperature. The temperature of the core can insulate rock liquids such as magma from volcanic eruptions. Such magma is almost everywhere inside the Earth's core, so with the current state of technology, nothing can maintain it in its pristine state before this temperature.
As for the question of what is in the core of the earth, with the current science and technology, we can dig into the core of the earth, and I will explain it here today.
-
There is magma, and the temperature of the Earth's core is very high, and the closer you are to the core, the warmer it becomes. The temperature of the core can insulate rock liquids such as magma from volcanic eruptions. It is possible to dig into the core of the earth, and inside the core of the earth, such magma is almost everywhere, so with the current state of technology, nothing can maintain it in its original state before this temperature.
-
Magma, there is a huge amount of hot magma in the earth's core. It can't dig to the core of the earth, and the deepest record of human digging is kilometers, which is still far from the depths of the earth's core.
-
According to the volcanic eruption, there is magma inside the earth's core, and with current science and technology, we can't dig the core of the earth, and the Soviets stopped digging more than 10,000 meters at that time.
-
What is in the core of the earth has not been studied yet, and it is not clear what there is, even with our current science and technology, we cannot dig into the core of the earth.
-
The Earth's core has not yet been able to determine what there is, and according to our current science and technology, it is not yet possible to dig into the core of the Earth.
-
I believe that many people are curious about whether the earth can be dug through and what is at the core of the earth.
-
In terms of mass, the Earth's core accounts for 16% of the Earth's total mass, the mantle accounts for 83%, and the Earth's crust, which is most closely related to us, accounts for only 1%. Are the earth's crust, mantle, and core all made up of rocks? Through the detection of ** waves, it was found that the entire earth's crust is made up of rocks.
The composition of the mantle is complex, and at the top of the mantle, the nature of the material is similar to that of the earth's crust, and it is thought that it is also the territory of rocks. As a result, scientists combined the uppermost part of the earth's crust and mantle and named it the lithosphere. In the mantle and core beneath the lithosphere, through ** waves, one can determine whether the substance is solid or liquid and how dense it is.
It is currently believed that the mantle is solid due to its ability to pass through the transverse waves in the ** wave. The Earth's core is more complex, and the outer core of the Earth, which is from 2,900 kilometers to 5,000 kilometers deep, cannot be penetrated by transverse waves, showing the characteristics of liquids; Below 5,000 kilometers to the center of the earth, it is solid. Based on the density of the earth's core, it seems that there are mainly metallic iron and nickel.
The Earth's core is a blazing world, the temperature can reach more than 7,000 degrees Celsius, and although on the surface, the melting point of iron is only 1,535 degrees Celsius, but under tremendous pressure, the iron in the heart of the Earth refuses to melt. Since the closer you get to the center of the earth, the greater the pressure, so the properties of matter are very different from the surface of the earth. For example, mantle material, although it is considered solid, but under strong pressure, mantle material will also exhibit fluid properties.
Just like the wax we usually use, it is solid at room temperature, when the temperature rises slightly, or the pressure is higher, the wax will become very soft, and the wax will be deformed with a gentle pinch with your fingers; The temperature continues to rise and the wax will melt into a liquid. Therefore, the scientific community still has different opinions on what kind of substance is in the depths of the earth and what state it is in, and it is difficult to draw conclusions.
-
The reason is that the temperature is so high deep underground that there is no drill bit made of any material that can drill very deep. Through the study of ** waves, people understand the internal situation of the earth.
