Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

These findings could lead to a better understanding of the inner workings of our planet and how life here will evolve over time. The Earth is made up of different layers. The outermost is the ...
