article imageAncient Rock Formations Support the Theory of Continental Drift

By Kyle Pallanik     Mar 24, 2007 in Technology
Harald Furnes, a geologist from the University of Bergen in Norway, discovered rock formations in Greenland that were formed 3.8 billion years ago, when the Earth was still quite young.
Furnes was actually in Greenland looking for evidence of early microbes when he discovered the oldest known evidence of this kind of rock formation to date. Prior to this find, the oldest sample of tectonic action known to scientists was 2 billion years old.
Despite modern knowledge of the theory of continental drift, we have only known about it for less than 100 years. If you live in California or other places where there are frequent earthquakes, you might find this hard to believe.
Plate Tectonics is a geological theory that has been developed to explain the evidence that the earth's crust moves on a large scale.
An interesting find in my opinion. We have still so much more to discover on our own planet. Our piece of rock has been around in the universe for a long time and has more stories to tell.
