Highlights

  • It was found that silicon is a major element and has constitutes about 5 % of the Earth’s inner core by weight.
  • It could be dissolved into the iron-nickel alloys.
  • Scientists For the study recreated the high temperatures and pressures found in the deep interior of the Earth’s core.
  • Scientists recreated alloys of iron and nickel and mixed them with silicon.
  • Scientists then subjected alloys to the immense pressures and temperatures that exist in the inner core.
  • Scientists discovered that this mixture matched what was seen in the Earth’s interior with seismic data.
