In Iceland divergent boundaries between plates can be watched directly. Plates also meet in Siberia, but in much more obscure way. Map showing the exact location is hard to find. There should be similar logic everywhere for boundaries between tectonic plates, so let us check Siberia:
The so called MORVEL model shows most plates location, so please compare it to what is shown here. The exact comparison can then be made in a similar way as for Iceland where every detail of how the plates are deviding from each other can be traced accurately with the mantle convection cell model.

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.
