Unexpected discovery about the earth's core.

Hello,Im cbgbyo65 and I will be talking about a current event that I call An unexpected discovery about the earth's core.Scientist's in seweden are saying that iron under extremly high pressure such as found in the inner earth take's unexpected propertie's, and this is important to understand the movement's in the earth "such as earthquake's".This happen's because the iron atom's in a piece of iron in room tempature are packed according to a certaint structure.In this case called body centered cubic or bcc.That means the atoms are relatively sparsely packed.When the iron is in greater pressure the atoms place them selve's differently in relation to each other and take another structure so called as the hexagonal close packed or hcp.That make's it more densely packed.so the higher the tempature and pressure the more stable the hexagonal close packed structure will be.In my opinion this could be wrong because they have also shown that iron unexpectedly revert's to bcc structure at extreme pressure's and tempature's.I found this information at brightsurf.com.
