What Did They Find?
Considering how many years they have been buried underneath many kilometers of rock, it’s unimaginable how the relics they found were in excellent condition. Scientists estimated the rocks to be over two billion years old!
Not What They Expected
Not only that, but as they dug deeper, they found more interesting stuff! Originally, scientists believed that the rock under the earth transforms from granite to basalt. This is what seismic waves project, it happens at 2 to 5 kilometers underneath the surface of the earth.
