Is the Core of the Earth Changing?

Underneath our feet, deep down below the Earth’s crust and its other layers lies the core, or where the planet’s magnetic fields are generated. However, experts now say it’s changing and there might be a new layer to count amongst the others.

00:00Underneath our feet deep down below the Earth's crust and its other layers lies the core or where

00:07the planet's magnetic fields are generated. However experts now say it's changing and there

00:12might be a new layer to count amongst the others. Researchers from the US, South Korea and Germany

00:17say water could be making its way deep down into the center most layers of our planet.

00:22When it trickles down some 1800 miles it eventually reaches the core mantle boundary

00:27mixing with silicon in the core and becoming silica. This process creates a somewhat new layer

00:31one that is both rich in hydrogen yet having very little silicon and they say it could change the way

00:36we think about how material transits from the core to the mantle with the researchers writing in their

00:41study that this quote points to a far more dynamic core-mantle interaction suggesting substantial

00:47material exchange. This is in contrast to previous studies which suggested there wasn't much of a

00:52transfer and means this is turning what we thought we knew about the inner workings of our planet

00:56completely on its head.
