Detailed explanation-1: -The fifth layer-the innermost inner core-lies at the Earth’s centre, within the inner core, the study published in Nature Communications on February 21, 2023, stated. The fifth layer is made of iron and nickel, the same materials that comprise the rest of the inner core.
Detailed explanation-2: -A team at Australian National University (ANU) has found evidence of a new fifth layer to the planet, an iron-nickel alloy ball in the inner core. The scientists found the hidden core by studying seismic waves that travel up to five times across the Earth’s diameter – previous studies only looked at single bounces.
Detailed explanation-3: -Earth has a fifth layer – the “innermost inner core”
Detailed explanation-4: -But this may be squashed in light of a new study that suggests Earth actually has a distinct fifth layer that’s been under our feet all along. Researchers at the Australian National University (ANU) say that the new layer they uncovered is located within Earth’s inner core.
