83% Informative

Researchers from the Australian National University used seismic waves generated by earthquakes to peer into the Earth 's molten core.

By tracing the path of these waves through the planet, the researchers found a region a few hundred kilometres thick where they travelled two per cent slower than normal.

This region is only found at low latitudes and runs parallel to the equator near the ceiling of the liquid outer core where the liquid section meets the mantle.

It could be responsible for driving our planet's protective magnetic field.
