On the division line between the N-American plate and the Eurasian plate lies the lake Laugarvatn in Southern Iceland. Baking bread in the sand at the side of the lake is an old tradition.

The bread has been in the boiling hot sand for 24 hours and is now fully baked.
The geothermal area is quite powerful. Look at the “border line” between the plates:

Clearly, this natural bakery is no usual place.

I am a geologist, graduated from the University of Iceland, and taught geology for a few years. I have gained some knowledge about Earth's inner structure, so I provide this website as my contribution to answer one of the greatest questions remaining within the realm of geoscience. Experiments show that the mantle should form convection rolls when close to the melting point. I took this literally, and calculated the dimensions and shape of these mantle convection rolls. Then I compare that model with the surface. This makes it possible to provide many interesting examples about geology found on my blog.
