there is a correlation between density of metals and their location in the interior of the earth ?
Answers
As the density of a substance increases, the relative buoyancy of that substance decreases. IE. The reason ice floats in water is because its density is less than the water in which it floats, therefore it has a positive buoyancy. But a glass marble will sink in water, because it is denser than the water in which it is sinking. Therefore, it has a negative buoyancy. (relative to the water) In the case of metals inside of the Earth, this is pretty much the same. The interior of the Earth is extremely hot. Temperatures are high enough to liquify most metals. This causes a condition that is not dissimilar to that of salad dressing that is left sitting undisturbed for a while. The densest parts of the dressing will settle to the bottom of the bottle. Those are usually the herbs and spices. right above those will be the oil component of the dressing, as the oil will be less dense than the solid materials, and have a higher buoyancy than the herbs and spices. on the very top, the highest buoyancy substance, the vinegar, will float over all the rest because it is the least dense substance in the bottle. Iron, being denser than nickel at a similar temperature (both assumed to be liquid) would therefore have a negative buoyancy inside of the nickel, and therefore would settle below the nickel in a high temperature, liquid metal environment. This would follow for each metal present in the center of the Earth. This is why these metals would form layers around the densest components at the very center of the Earth.
