Why is the temperature of the Earth s core so high, but it can t reach the ground for billions of ye

Because the Earth's core is so far from the Earth's surface, and it is blocked by dirt, rocks, and water, this greatly reduces the spread of temperature.

There are several layers of the earth, and the heat is dispersed in the process of transfer, and the remaining heat energy that cannot be dissipated is dispersed in other forms such as volcanic eruptions.

Because there is a layer of crust on the surface of the earth's core, he can isolate the temperature The temperature under the ground is magma, there is a magma layer and a lime layer, all of which can be temperatured, so it cannot be transmitted to the ground.

Although the temperature of the Earth's core is high, the Earth is composed of several layers, and the material between the crust and the Earth's core will prevent the temperature from propagating, causing the heat of the Earth's core to disperse.

Because the density of the earth is very high, it is difficult for the core temperature to be emitted, so the nuclear temperature is still very high.

Because its heat is generated by the process of its own use, the energy it produces during movement is very high.

Because the earth is now in its prime, the temperature is very high, and during this period, all activities are in a more intense and vigorous stage.

In order to understand the state of the Earth's interior, it is necessary to trace the history of the Earth's formation. According to the experts' long-term monitoring and scientific research and their corresponding reasoning and analysis, it is felt that when the earth was first established, the initial whole process of its passage was basically the same as the whole process of the establishment of the key of the sun and other planets, all of which were to absorb more and more interstellar imperial matter under the action of the gravitational field.

As a result, the kinetic energy accumulated in the whole process of the impact of a large number of substances and their collapse is converted into the heat of the core, and then promotes the continuous increase of the temperature of the core environment, which is just the key to the sun, at that time, the total output of the interstellar empire absorbed by the sun, accounting for the vast majority of all the star test-tube embryos in the solar system, and then provoking the critical value of the nuclear reaction of the internal structure of the material, and the key to other accumulated materials is only to digest and absorb the surrounding substances that are not digested and absorbed by the sun by means of re-digestion. and its interstellar imperial matter blown by the solar wind, to slowly improve its quality.

Eventually, rock planets and vapor planets will be gradually perfected according to the distance between the sun and the sun. The Earth was born in a protoplanetary disk 4.5 billion light-light-years ago, followed by the Sun, three rock-formed planets, four vapor giants, dwarf planets and some of their asteroids, which together form the regular operation of the solar system that we see today. Despite the 4.5 billion light-years of Earth's existence, there are three key pyrogens in the deepest part of the Earth that cause the Earth's core to remain hot:

The heat that occurs when the earth is formed and expanded, and this heat does not subside.

frictional warming, caused by the movement of higher density of the main raw material down to the planet's core; The heat formed by the nuclear decay of radioactive material. Heat leaves the earth for a very long time. This is also maintained by the "thermal convection" transport of heat within the liquid outer core and solid mantle and the slower "transport" of heat by the non-thermal convection of the surface layer (e.g., the Earth's tectonic plate at the surface).

The emergence of the Earth's atmosphere has contributed to the relative stability of the Earth's surface temperature, and at the same time, global warming has prevented the outflow of surface heatNor will it contribute to the overall warming of the planet too quickly.

I think the main reason why the nuclear temperature is still very high is mainly related to the volume of the earth. The main reason is that the mass and volume of the earth are very important, and if the volume is very small, the core of the earth can easily cool due to the heat dissipation.

Although the earth has been consuming heat outward, because the heat generated by the earth itself and the heat lost are almost the same, the earth is now cooling very slowly, and the temperature is relatively stable; Because although the earth has been dissipating heat, the heat he dissipates is about the same as his own heat, so the temperature is still very high.

The main thing is the core of the earth, which is very far from the surface of the earth, and it has not changed in any way, so the temperature is still very high.

This has to do with the mass volume of the Earth. The depth of the earth is very high, and the heat dissipation capacity is not particularly strong.

1. Because the inner core of the earth is a solid iron sphere, about the same volume as the moon, the outer core of the vigorous movement around it is mainly composed of liquid iron-nickel alloy;

Tests carried out at the beginning of the decade determined the iron"Melting curves", they point out that the temperature of the Earth's core is 5,000 degrees Celsius; Using the world's strongest X-ray source at the European Synchrotron Radiation Facility, the research team of the latest test reproduced an environment under the same pressure as the Earth's core.

1. The core part of the Earth's core, which is located in the innermost part of the Earth. The radius is about 3470 km, mainly composed of iron and nickel elements, high density, the average density of the earth's core material is about grams per cubic centimeter, and the temperature is very high, there are 7000 .

2. The structure of the Earth is similar to that of other terrestrial planets, which are layered, and these layers can be determined by their chemical and rheological properties. The Earth possesses a silicon-rich crust, a very viscous mantle, an outer core of a liquid, and a solid inner core. These insights into the Earth's internal structure are based on physical evidence and some inferences, including material ejected by volcanoes and waves.

The interior of the earth, from the surface of Gutenberg to the center of the earth, is called the core.

Because it is surrounded by the earth's mantle and crust, it cannot escape, and even if it cannot bear it, it can only be carried to death.
