Iceland is divided by the Mid-Atlantic Rift; some parts of it, such as the Westfjords and Reyjavík, are on the North American tectonic plate, while others, such as Vatnajökull glacier and the East Fjords, are on the Eurasian plate. Iceland is the only place in the world where this rift is above sea-level, and nowhere can you see the edges of both plates as clearly as in Þingvellir.
