## Resource

We finally end our great Greenland adventure with one final question: how did all these diverse rocks become squeezed together, 3.6 billion years ago? The answer to that question can tell us a lot about how the early Earth worked. According to some folks, plate tectonics was very similar to today. To others, Earth was a very alien world indeed. Along the way, we'll visit trenches off the coast of Japan, and turn our hands into tectonic plates. Dylan also has an exciting announcement : he has a new visiting professor job at Gustavus Adolphus College in Minnesota! Thanks to everyone for their support.
