Digging up an old thread. Im interested in tectonics too.
Basically, the face of the earth is made up from large plates of land that 'float' on a 'sea' of molten rock.
First of all, yes, this does exist. The government doesnt place dynamite under mountains and call them volcanoes. All through history there is undeniable evidence of volcanic activity.
At that, there is also undeniable evidence of tectonic movement, as stated here, the saint andreas fault is an example.
So, you would have to agree that we do have magma below our feet, and we do have tectonic plates.
Firstly, why doesnt the magma MELT your ice wall?
Secondly, why doesnt the movement of the tectonic plates fracture and damage this wall? By now surely one would have broken down the side of the wall.
