The ultimate in systemic process?

This week I have traversed the boundary between the Eurasian and the North American tectonic plates. My daughter and I have promised ourselves a trip to Iceland for years - I date our joint interest from a project she did at school about 10-12 years ago. She puts our conviction a little later when as a family we were engrossed with The Earth Story - a fantastic TV series.

Have a look at how these tectonic plates mesh together and see how the mid Atlantic ridge bisects Iceland - a major hotspot on the ridge, and the reason for Iceland's existence. Having seen the TV series it is easy to look at the landscape and imagine the earth's crust as a dynamic flow, moving at about 2cm per annum.

The development and extent of use of geothermal power is also impressive.
