I have heard of carbon storage, do you know?The largest carbon library on the earth is actually under our feet

Most of the carbon on the earth may be located in the foreign nucleus of our planet

This discovery or explanation of the difference in the quality of the ground nuclear

Earth liquid foreign nucleus may be the largest carbon reserve on the blue star

0.3%to 3%, this proportion looks small, but considering the thickness of the entire foreign nucleus (1355 miles (2180 kilometers)), we will get a huge amount of carbon There will be 24 zero behind these numbers!)

"The carbon that exists in the Earth's nuclear will help us unveil the mystery of the quality of the Earth's nuclear", "said scientists.

"The composition of the ground nuclear is a core issue of solid geoscience," Mainak Mookherjee, the co -author of the research, said in a statement that Mukji is an Earth, ocean and atmosphere from the Florida State University. The Department of Geology, the Department of Science, "We know that the ground nucleus is composed of iron, but the density of iron is clearly higher than the density of the nucleus."

Therefore, scientists firmly believe that there must be elements such as carbon more "carbon" to reduce the density of the nucleus.

According to researchers, this is not the first time that scientists have tried to determine the carbon content in the global foreign nuclear nuclear, but by considering other "light elements", such as oxygen, sulfur, silicon, hydrogen, nitrogen, it is estimated to be the composition of the extra -earth nucleus. Then the carbon content is optimized, which is the first one.

It is not easy for us to study directly observation means to be hidden in our underlying 1800 miles (2890 kilometers), so scientists do it, and analyze the chemicals of foreign nucleus by measuring vertical sound waves and building computer models. constitute.

In this new study, scientists have compared the speed of vertical sound waves on the earth with different quantities of iron, carbon and other "light element" computer models to find the best matching.

"When the value of the sound wave transmission is the same as that the value of the sound wave on the earth is the same, we know that the chemical composition in the foreign nucleus is consistent with the model." Suraj Bajgain said in a statement. Baggigan is also a postdoctoral department from the Department of Earth, Ocean and Atmospheric Sciences from the Florida University.

This new study has reduced the range of carbon content on the earth to more than 990 to 6,400 percent of them. Researchers believe that 93%-95%of them are in the ground nuclear (whether the kernel or foreign nuclear). So the nuclear stool has become a well -deserved carbon storage library.

Researchers also said that understanding the elements that humans live in the earth can help scientists better understand the composition of blue stars and other planets.

"People will naturally ask, where do these carbon elements come from? How much carbon contains at the beginning of the earth?" Mu Keji said. "How much carbon is left on the earth? How does these carbon be preserved? In what kind of form is they transformed between different carbon storage? The research we do help us answer at least one of them- - What is the total carbon reserves on the earth. "

Now let's go back to analyze the earth. The earth is the third planet from the sun, and it is also the only planet known to exist. Although there are a lot of water on many celestial bodies in the solar system, only the earth has liquid surface water. About 71%of the surface of the earth is covered by the ocean, which makes the polar ice distributed on the earth, lakes and rivers are dwarfed. The remaining 29%of the earth is land composed of the mainland and islands. Looking on, the surface of the earth is actually composed of several slow -moving structural sectors. The sectors collided with each other, producing mountains, volcanic and earthquakes. Under the plate is the liquid nucleus of the earth. The magnetic field produced by this part shaises the magnetic layer of the earth, which makes the destructive solar wind deflection.

The atmosphere of the earth is mainly composed of nitrogen and oxygen. Due to the location, solar energy is mainly concentrated in the equator instead of the extreme, but the effect of atmosphere and ocean current ease this difference. Specifically, water vapor absorbs heat from the ground and brings the atmosphere, which moves the heat from the equator to the pole, with an average global temperature. The above is a good aspect, but the greenhouse gases similar to carbon dioxide in the atmosphere will trap solar energy on the surface of the earth. At the same time, the climate in a region is not only related to dimensions, but also affected by altitude and ocean. Similar to tropical cyclones, thunderous and heat waves will occur in many places, deeply affecting people's lives.
