Using high-resolution imaging taken over many trips to Antarctica, geologists have discovered what could be an ancient sunken ocean floor beneath the Earth's surface.
The Earth was discovered to have a "secret" inner core that no one knew about until now. A new study defies what has been known to humans for decades now, where previous knowledge about the four layers of the Earth sees debunking from this latest discovery.
According to seismologists from The Australian National University (ANU), data gathered from seismic waves caused by earthquakes has shed new light on the deepest parts of the Earth s inner core.
