Drilling to the innermost core of Earth is, at this time, not a possibility, but by using an alternative research means scientists have discovered that the center may have a center of its own.
Drilling to the innermost core of Earth is, at this time, not a possibility, but by using an alternative research means scientists have discovered that the center may have a center of its own.
Researchers from the US and China used 20 years of seismic data collected during earthquakes to measure the changes in echo intensities as the waves moved through the earth’s layers.
Their findings suggest that the approximately moon-sized inner core is actually made up of two distinct areas, with one inside the other.
Among the most notable differences between them is their iron crystal alignment.
Those in the central area, or the core’s core, run east to west making them parallel with the equator.
Conversely, those in the outer reaches run north and south, in line with the poles.
