The elemental secret in the heart of the Earth

Laboratory scientists at the California Institute of Technology recreated the harsh conditions within the Earth's core, paving the way for understanding the formation of the Earth and how magnetic fields work on the planet. our.

According to Daily Mail , scientists have known for years that iron is the main element in the Earth's core, but so far we have not understood what this element will look like when compressed under tremendous pressure inside the heart. land. Understanding what is going on in the Earth's core will help scientists understand how Earth is formed and why the Earth's magnetic field works now.

Studying iron elements in the Earth's core will help us understand
more about the formation and operation of Earth's magnetic field.

Jennifer Jackson, a professor at the California Institute, said careful consideration of iron properties is very important in understanding the behavior of the earth. The team used a diamond anvil to compress a small piece of iron with pressure equal to 17 million times the pressure we could feel on Earth, then use X-rays to measure the vibrations of they compare with the results of tremors in the center of the Earth. The results show that in the core of the Earth, iron melts at 5500 degrees Celsius and this helps us to know out of iron and what elements are in the Earth's core as well as dynamo theory that created magnetic fields.

From the experiment, the team came closer to estimating the melting temperature of iron at the boundary of the inner hardening layer and the earth's outer liquid layer of about 5800 degrees Kelvin. By comparing the density of the iron in the laboratory to the same pressure and temperature conditions as the density of the Earth, they found that iron at the boundaries of these two layers had a density of more than 5.5%. compared to the inner hard core. Professor Jackson said that with the new data on iron elements, there will be more discussions about the Earth's core and we will also narrow down the amount of impurities needed to create the dynamo effect, one effect. The application helps maintain the Earth's magnetic field from the Earth's core. Two light elements, silicon and oxygen, can exist in the earth's core, but there has been no detailed study on this issue. And that is the reason to expand the scope of this study.
