The inferred pressure and interior temperature at the boundary between Earth's outer core and inner core are 3.1 million atmospheres pressure and an interior temperature of 6300.
The composition of the earth's coreAs we know, the crust and mantle are rich in minerals. However, the Earth's core is mostly composed of iron and nickel metals. We also found iron-soluble materials called siderophils. These elements are completely uncommon in the earth's crust and, therefore, are called noble metals. In these precious metals we find cobalt, gold and platinum.
Another key element found in the atomic nucleus is sulfur. 90% of all the sulfur on Earth is in the core. The core is known as the hottest part of the entire planet. The internal structure increases temperature with increasing depth. However, given the distance of more than 6,000 kilometers that separates us from the surface of the Earth to the Earth's core, it is quite difficult to know at what temperature this center of molten iron and nickel is located. The temperature is not always the same. They fluctuate depending on pressure, Earth's rotation and the composition of the elements that make up the atomic nucleus.
Because convection currents cause materials to move, some material enters "new" into the core while others exits again and no longer melts. This is due to the proximity or distance of the materials from the center and their very high melting points.
General research says that the temperature of the earth's core From 4000 degrees Celsius to 6000 degrees, approx.
