Slowly but surely, the earth below us is moving. Of course, this movement takes place over millions of years, and is undetectable (most of the time).
This bridge in Iceland joins the Eurasian and the North American tectonic plates.
The Leif the Lucky Bridge spans between continents in Reykjanes peninsula in southwest Iceland across the Alfagja rift valley. "Rift" means the valley is being created by the land being pulled apart, in this case by the movement of the plates.
Gives a whole new meaning to the term "expansion bridge," doesn't it?
In addition to answering questions, good science often asks questions. Mine is, how fast are the plates moving apart, and how long will the bridge last? I just want to be sure I get there before the thing falls into the valley below. Walking from North America to Europe would be pretty neat.
