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.
