The Earth’s outer shell expanded during massive growth 3 billion years ago



About 3 billion years ago, The EarthGeologists have found that the crust swelled during massive growth.

At that time, just 1.5 billion years after the formation of the Earth, the mantle – the layer of silicate rock between the crust and the outer core that was more active in the past – heated up, causing the magma from that layer to flow into fragments of older bark above it. These fragments acted as “seeds” for the growth of modernity continents.
