What is there in the deepest part of the earth?

The structure of the earth.

Scientists divide the earth into three depth concepts according to the different speed of wave propagation, namely the crust and the mantle.

Core. The earth's crust is a solid crust, and the average thickness of the earth's crust in the continental part is about 30 kilometers, while the plateau part is about 60 kilometers, which is about the radius of the earth.

of 1%. The upper layer of the earth's crust is mainly granite, and the lower layer is basalt.

According to scientists' research, the age of the earth's crust is basically less than 2 billion years old, and the earth is about 4.6 billion years old, so it can be inferred that the earth's crust was formed later!

The mantle is about 3,000 kilometers thick and is mainly composed of dense rock-forming material, and the mantle is magma.

Many substances exist in a moldable fluid state.

The average thickness of the Earth's core is about 3,400 kilometers, and the pressure and temperature of the Earth's core are very high, scientists speculate that the temperature of the Earth's core can reach 5,000 degrees, and the pressure can be hundreds of millions of kilopascals.

Is there life deep in the earth?

Scientists have found that at a depth of about 10 kilometers underground, there are some very special biospheres.

They live in a dark, damp, and scorching environment, and many of the creatures here are strangely shaped, and scientists can't be sure if they have intelligence, after all, with the current technological conditions, humans can't reach this place smoothly!

What exactly is in the Earth's core?

According to scientists, the mass of the earth is about 59 trillion tons, and according to the state of the earth's surface, the weight of the earth is far from heavy, which means that there is a very dense substance deep in the core of the earth, what exactly is this substance? Scientists still don't have a clear answer.

Does an underground civilization exist?

Scientists have not found the existence of an underground civilization, and with the current scientific and technological means of human beings, it is impossible to create an underground kingdom dozens of kilometers underground. But for the earth's crust tens of kilometers deep, there are indeed conditions for the survival of such intelligent life!

According to modern scientific theories, the center of the earth is a huge ball of liquid iron, so in the deepest part of the earth's earth, there is liquid iron.

Most of the material in the interior of the earth is iron, and the deepest part is also the hottest place, where there is a lot of lava, and the material from volcanic eruptions is the material in the interior of the earth.

The deepest part of the earth is the core of the earth, which is the hot magma, which can reach temperatures of 5,500 to 6,000 degrees.

The deepest part of the earth is the core.

The Earth's core is the core part of the Earth and is located in the innermost part of the Earth. The radius is about 3470 km, mainly composed of iron and nickel elements, and the density is high, and the average density of the earth's core material is about grams per cubic centimeter.

The mass of the Earth's core accounts for the mass of the entire Earth, and the volume accounts for the volume of the entire Earth. According to the changes in the ** wave, it is found that the earth's core also has the difference between the outer core and the inner core. The interface between the inner and outer cores is about 5155 km.

Since the transverse wave of the ** wave cannot pass through the outer core, it is generally assumed that the outer core is composed of molten or near-liquid substances composed of iron, nickel, silicon, and other substances. The liquid outer core flows slowly, so it has been speculated that the formation of the Earth's magnetic field may be related to it. Since transverse waves are present in the core, the core is solid.

Why don't humans explore the center of the earth?

Everyone knows in geography class that the Earth's interior is composed of the Earth's crust, mantle, and core. But it is still quite unfamiliar to human beings, and scientists have been constantly exploring the mysteries of the universe, and the deepest depth of human exploration of the earth is 12,262 meters.

At present, many human instruments have not reached a certain level, and the so-called exploration of the center of the earth still stays at the level of the earth's crust, that is, the surface layer of the earth. And because the situation is more complicated, many equipment and instruments need to be replaced frequently, so the speed is extremely slow.

In addition, those who have studied geography know that the further you go, the higher the temperature will be, the boundary temperature between the mantle and the core will reach 4,000 degrees, and the temperature at the center of the earth will exceed 6,000 degrees, so it may have been roasted before exploring the more core location.

There is a lot of pressure in the heart of the earth, and the maximum pressure may exceed 3.6 million atmospheres. However, at present, the most powerful human instrument can only withstand 1,000 atmospheres, and the gap is still relatively large.

Whether the Inner Civilization and the Inner Earth Man really exist.

The question of the geocentric civilization is also often discussed, and whether the so-called geocentric kingdom created by the geocentrics is real has always troubled the world. There is no way to verify the legend of the geocentrics, since when it began, but there is a lot of information that can prove the existence of the geocentrics.

Many people speculate that there is a very mysterious inner kingdom in an unknown part of the earth, which can be reached through a mysterious passage. But these are just speculations and inferences, and there is no more evidence to prove all of this. In everyone's mouth, the geocentrics are more similar to humans, but the only difference is that the geocentrics are pale and terrible, and their faces look like aliens, but their body size is no different from humans.

Since the existence of the geocentrics is still an unsolved mystery, the so-called warnings from the geocentrics to the earthlings rumored on the Internet no longer exist, and the reason why humans do not explore the geocentrists has nothing to do with the geocentrists. Although there are still many people who are curious about what the earth is like, the mystery has not yet been solved.

Does Inner Earth really exist? Why can humans explore space but not the underground?

The center of the earth is an area where many elements such as iron converge and has a large amount of magma.

The reason why we don't explore it is because we haven't reached a certain level of science and technology. Because the temperature of the earth's core can reach more than 6,000 degrees, and the pressure is too high, equivalent to more than 1,000 atmospheres, human instruments cannot withstand such harsh conditions. On the other hand, the former Soviet Union explored the center of the earth, but the excavation was abandoned to a certain extent, because the drill bits they used could no longer go deeper.

Before that, let's discuss the internal structure of the Earth, from the outside to the inside, the crust, mantle, and core. The surface of the earth's crust is very thin, and the interface with the mantle is mohorovi i intermittent. Its average thickness is only 17 km.

Compared to the average radius of the Earth (6378 km), it is even much smaller than an eggshell. The thickness of the eggs. To date, humanity has never been able to break through this thickness.

In addition to rocks and various mineral deposits, the largest amount of underground storage is groundwater and magma, and the reason why the center of the earth has not been explored is because the temperature of the center of the earth is too high, the pressure is too great, and the current technical conditions are difficult to achieve.

If you could go to the deepest part of the earth, what would you find? Probably the most famous is Victor Wiskovo, who from 2018 to 2019 led expeditions to the deepest parts of the five oceans, completing 87,000 kilometers of voyages and 39 dives in just ten months. However, if you want to reach the Mariana Trench, the deepest point on Earth, it will cost you about $750,000.

So what will you see?

The bottom of the Mariana Trench, known as the Challenger Deep, is about 11,000 kilometers above the surface and takes more than two hours to reach by submarine. When you dive down to 200 meters, you will find that most of the jujube leaky marine life lives at this depth, and then the surrounding environment will become darker and darker, and the marine life will become less and less, but occasionally you will see huge whales diving for food. When you dive to a depth of 1,000 meters, you'll see the fangs of the first deep-sea creature.

This fish is about 16 centimeters long, and the two huge teeth on the front of its mouth are where its name comes from. To make room for these two teeth, two slots have evolved specifically next to its brain. When you get to 2,500 meters below the seabed, it's hard to see whales, they don't usually dive to such depths, and there isn't enough food here.

Eight thousand meters below the sea, you'll encounter the Mariana snail, but the water pressure at the bottom of the ocean is about 1,100 times higher than the atmospheric pressure at the surface. If you weren't in a submarine, you'd be squashed by the tremendous pressure, but these little snails can withstand that pressure. I have to say that the evolution of living things is really amazing.

When you come to the Challenger Deep, you're about 11,000 meters above sea level, and there's no treasure here. There are no lost civilizations, and megalodons have never been seen here, except for a few small deep-sea creatures that look like shrimps, only about three centimeters long and covered in white. It's disappointing, but it's the deepest part of the world.

The deepest part of the earth is nothing more than the earth's core, and the earth's core is likely to be filled with magma, and it is accompanied by unbearable high temperatures for human beings, and under this high temperature, it is almost impossible to dismantle the tung and have anything to bear, so there will be nothing special in the depths of the earth.

The Earth's subterranean internal structure is divided into three concentric spheres: the core, the mantle, and the crust.

Crust: The earth's crust is actually broken by multiple groups, many blocks of different sizes are composed of cracks, and its exterior shows a high and low undulating shape, so the thickness of the earth's crust is not uniform: the average thickness of the crust under the continent is about 35 kilometers, and the thickness of the crust of the Qinghai-Tibet Plateau in China is more than 65 kilometers.

The thickness of the crust beneath the ocean is only about 5 to 10 kilometers. The average thickness of the Earth's crust is about 17 km, which is only a thin layer compared to the Earth's average radius of 6,371 km.

Mantle: The mantle is about 2,865 kilometers thick and is mainly composed of dense rock-forming material, which is the largest and most massive layer in the Earth's spring rule. The mantle can be divided into two layers, the upper mantle and the lower mantle.

It is believed that there is an asthenosphere at the top of the upper mantle, which is presumed to be caused by the melting of rocks due to the concentration of radioactive elements, metamorphosis and exothermy, and may be the source of magma. The part of the mantle above the asthenosphere and the earth's crust together form the lithosphere. The temperature, pressure, and density of the lower mantle all increase, and the matter is a plastic solid.

Earth's core: The average thickness of the Earth's core is about 3,400 km. The earth's core can also be divided into three layers: the outer core, the transition layer and the inland core, the thickness of the outer core is about 2080 kilometers, the material is roughly liquid, and the source shed can flow.

The thickness of the transition layer is about 140 km. The inner core is a sphere with a radius of 1,250 kilometers, and the matter is probably solid, mainly composed of metallic elements such as iron and nickel. The temperature and pressure of the Earth's core are very high, estimated at temperatures above 5,000, pressures of more than 100 million kilopascals, and densities of 13 grams per cubic centimeter.

The deepest is the Mariana Trench at 11,034 meters, which is the deepest point on Earth.

1. The Mariana Trench, also known as the "Mariana Islands Trench", is the deepest trench on the earth, which is located in the western North Pacific Ocean seabed, near the east of the Mariana Islands. The Mariana Trench is already deeper below sea level than the highest point of Mount Everest.

2. The Mariana Trench is located at 11

20 n, 142°, that is, in the northeast of the Philippines, the Pacific Ocean floor near the Mariana Islands, between the Asian continent and Australia, from the Iwo Islands in the north to the vicinity of Yap Island in the southwest. It has the Aleutian, Kurile, Japan, Ogasawara and other trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers, an arc, an average width of 70 kilometers, and most of the water depth is more than 8,000 meters. The deepest point is in the Fichaz Abyss, at 11,095 meters, which is the deepest point on Earth.

The trench is estimated to have formed 60 million years ago and is part of a series of trenches on the ocean floor in the western Pacific Ocean.

3. Guess the reason for the formation.

The Mariana Trench is located east of the Mariana Islands in the western North Pacific Ocean, and is an arc-shaped depression on the ocean floor that extends for 2,550 kilometers and is 69 kilometers wide on average. There are smaller steep-walled valleys at the bottom of the main trench. In 1957, the Soviet survey ship measured a depth of 10,990 meters, and later a new record of 11,929 meters was set again.

In 1960, the U.S. Navy used the French-made "Trieste" deep-sea submersible to set a record of 10,911 meters in the trench. It is generally believed that the oceanic plate and the continental plate collide with each other, and because the oceanic plate rocks are dense and low, they subduct under the continental plate, enter the mantle and gradually melt and disappear. Ocean trenches are formed where collisions occur, and island arcs and coastal mountains are often formed on the side close to the mainland.

These places are all areas of intense geological activity, manifested by volcanic eruptions and **.
