Although information has been obtained for years on the Composition of the Earth's Core, the truth is that its precise formation and what is found there even today is a mystery, however we bring you all the known information about the Inner Core of the Earth right here.
What is the Earth Core?
The human has achieved an enormous advance compared to hundreds of years ago, at present changes and transformations are constant in all aspects of life, time runs and never stops, we have even managed to reach the moon and we are in process of being able to reach other planets, the possibilities of what we could achieve in a long period of time are endless.
However, one of the greatest mysteries of the earth is just below our feet, it begins about 3.000 kilometers below and continues to advance until it reaches its center and consequently the center of the Earth at 6.000 kilometers, to be more precise, it corresponds to 32% of it.
It has not been possible to reach it because it is physically impossible, since it is speculated that temperatures in the core can reach 6.700°C, obviously it is a heat that the human body cannot withstand, adding to this there is also the pressure generated by the field magnetic that does not allow any vehicle to advance much further.
The lowest that the human being has been able to reach has been an enormous advance made in Russia by researchers for scientific purposes, the project was based on being able to reach 15.000 meters, however the temperatures were double those expected and after some complications that caused the project to be delayed, they almost managed to reach 12.300 meters below the earth's crust, in 2008 the project was canceled due to lack of budget.
Origin of the Earth's Core
The earth had its origin as a fusion of various components of space, everything began as a mass of heat that over time gave shape to all the layers that we already know today, the heavy materials went deeper , being able to conserve heat in the core and the less dense materials were conserved on the outside, until they became layers and formed the Earth structure.
Composition of the Earth's Core
Many theories have been proposed about what the Composition of the Earth's Core, but in the same way, many of them have had to be disproved, as was done at the time with the theory that the center of the Earth was made of gold since its density is very close to that of this element, without However, many scientists agreed that the core is mostly iron combined with other metals, but in smaller amounts.
This last assumption is based more than anything on logic, since one of the most abundant materials in the entire universe is iron, it was investigated that most of the weight of the entire earth is found in the earth's core and on the surface there isn't as much iron as the stats would suggest, so expect most of this mental to be concentrated in the core.
There are also many elements that are rarely seen in the crust and mantle, one of these may be sulfur, since there is only a very small part of this component outside the core.
The most interesting of Composition of the Earth's Core were the processes that had to be passed through to come up with these theories and what we can also consider as more precise information, mainly the data was obtained through the observations made for the study of earthquakes, thanks to the which could be given with an approximate calculation of the Earth dimensions.
All the internal movements of the earth emit waves that spread throughout the planet and of course in some regions it is felt more than others, in which the movement becomes almost imperceptible.
External nucleus
A very important piece of information obtained from the vibration recorded by earthquakes since the 30s is the fact that the waves change as they travel through the structure of the planet and that makes the vibration in some regions different, since knowing this, in the 60s a very important earthquake was recorded that came to emit a kind of wave that scientists in other parts of the world were waiting for, but never came.
Some time later, many investigations of the event were made, reaching the conclusion that the waves were not transmitted because they could not travel through the liquid of which the outer layer of the nucleus is composed. The radius of the outer core is 2.250 kilometers and it is composed of molten iron that, due to extreme temperatures, is unable to solidify.
Internal Core
Scientists describe it as a huge sphere whose radius is approximately 1.255 kilometers, it is very heavy and hot since its temperature can exceed 5.500 ° C. There is a significant separation between the two nuclei known as the Bullen discontinuity, which allows this sphere to move independently of the rest of the earth and recent studies indicate that it has a slightly higher speed than the planet.
At first this was very strange for the researchers, discovering that the inner layer of the nucleus was solid and not liquid like the other, later they understood that it was because, although the temperature in this layer would melt the metals, the pressure in the inner core is so strong that it does not allow these elements to separate.
Magnetic field
The outer core is of vital importance, since the movement of iron in its liquid state creates an electrical charge that expands, with the help of the other metals found on earth that also generate the same charge but to a lesser extent, all this energy manages to reach space forming the magnetic field.
The inner core could also cause this effect, as a huge ball made up of metals that are very magnetic, however the temperature in the outer core is so high that the metal completely loses its magnetic force.
Importance of the Core
Like many elements, materials and processes that exist in the world, Composition of the Earth's Core has a huge importance, because it is vital not only for human life, but for the very structure of Planet Earth, since the nucleus is a huge magnet that attracts all the components by which the earth is formed and mainly it is the one that gave origin to the formation of the layers through a process called planetary differentiation.
The magnetic field, which is the effect of the nucleus, is what allows the existence of the atmosphere which protects life on the planet by limiting the entry of the powerful energy that is produced by the ultraviolet rays of the sun, it is also capable of stopping the impacts of any space object that enters into orbit with the earth
This field also allows the well-known use of the compass, which was invented in the twelfth century and allows us to orient ourselves by means of magnetized needles that point to both poles, this ingenious invention allowed navigators to know in which direction they were traveling through of the vast sea, the only places where a compass does not work properly is at the poles.
Even many animals can locate themselves thanks to the strength of the magnetic field, guided by it they can move from one place to another and migrate when necessary. Turning to plant life, there are scientific practices that show that plants can form and grow much faster under the protection of the field.
A clear example of the importance of the magnetic field for human life is the disease called space sickness and it happened in the first expeditions to space, since the human body is so accustomed to life on the planet that when travelers went out into space , they suffered from some diseases and the body began a stage of deterioration, rendering some vital organs useless.
These effects were attributed to the fact that there are no magnetic fields adapted for human life in space and to minimize these effects they had to create a field around the ship that was not 100% effective, but fulfilled its function and delayed the advance of these effects.
We can conclude that the terrestrial core, all its formation and functions are of utmost importance so that life can form on planet earth, the world as we know it right now would not be possible without the inner and outer core. Just enough to tell you that the point where we are now would be nothing, possibly another space void in the vast universe.
