A new study by the Australian National University (ANU) confirms the existence of a fifth “innermost inner core” of the Earth, shattering past perceptions that the Earth’s structure has only four layers. The study was published in the Journal of Geophysical Research.
In a press release from the Australian National University, lead author Dr. Joanne Stephenson pointed out that the traditional Perception of the Earth’s structure is that the crust, the Earth’s letters, the outer core, and the inner core are the same as the inner core. The research team used seismic data from the International Seismological Center with algorithms to find changes in the iron structure in the Earth’s core.
The study shows that there is a previously unknown boundary about 650 kilometers from the center of the Earth, and this evidence also points to two separate cooling events in the Earth’s history, while the cause remains a mystery. textbooks now.”
The average thickness of the Earth’s layers is known to be 17 kilometers for the crust, 2883 kilometers for the geoid, 1742 kilometers for the outer core, and 1200 kilometers for the inner core, while the junction between the core and geoid is the Goo discontinuity, and the junction between the geoid and crust is the Mohs discontinuity; the new boundary discovered by the Australian National University is located among the known inner core.
