Under the Banda Sea in Indonesia, the Earth’s core is growing extremely fast while below Brazil it is extremely slow.
Research by geoscientist Daniel Frorst of the University of California at Berkeley found something unusual when seismic waves roam the globe: They appear to travel 3% faster when moving vertically (pole to pole ) in relation to the travel time from East to West. .
They established new models of the structure of the Earth based on seismic data and concluded that the solid core of the planet is growing faster than one side, namely the lower part of the Banda Sea in Indonesia, while the opposite side (under Brazil) is growing very slowly. This leads to the fact that the earth’s core is no longer the sphere in the center as we imagine it, but gradually deforms and tends to move to one side.
“There was a time when our planet did not have a solid core. The innermost part of the Earth contained a mass of molten matter billions of years ago, after which liquid iron began to cool. and solidify. The Earth into a giant heap of crystalline iron, which continues to grow “- Science Alert, citing research.
This warped sphere called the “Earth’s core” also grows more slowly below the poles, so it gradually takes on a more flattened shape. Growth at the poles was up to 40% lower than average, while growth at the equator was up to 130% higher, according to Dr Frost. Growth rates in the eastern and western equatorial regions are also different, with points up to 160% above the world average.
The study, which was just published in Nature Geoscience, also confirmed that this erratic growth has occurred since the planet’s core started to become more solid, about half a billion to 1 ago. 5 billion years.
