In high school science class, textbooks often feature a recognizable image of the Earth and all its layers—currently, that’s the crust, outer and inner mantle, and outer and inner core.

The inner core grows (and rotates) in response to the coupling with other layers, which are both gravitational and electromagnetic," Pham said. Earth isn't the only place that experiences quakes.

The core is split into the outer and inner core, and this is where a team of researchers from The Australian National University (ANU) examined seismic wave data from 200 magnitude-6 and above ...

Key Takeaways on Earth's Inner Core Earth's inner core is solid and blistering hot. For decades, scientists have known ...

Earth has an 'innermost inner core': Scientists say hidden structure may be a huge ball of IRON measuring 800 miles wide. New findings may improve our understanding of Earth's formation and evolution ...

Anisotropy measurements of Earth’s inner core based on these waves’ travel times revealed previously-unrecorded data about Earth’s interior structure.

Geologists today have a good understanding of Earth's interior, based on pioneering work by Isaac Newton and Danish seismologist Inge Lehmann in the late 17th century and early-to-mid 20th century, ...

Researchers are still discovering more about the Earth's center.A team at Australian National University (ANU) has found evidence of a new layer to the planet sitting within the inner core. This ...

Not long ago it was thought Earth’s structure was comprised of four distinct layers: the crust, the mantle, the outer core and the inner core. The findings, published in Nature Communications ...
