17. I doubt that nuclear reaction is responsible for geothermal energy..
I dont think there is sufficient fissile uranium at the earth core to sustain a long term nuclear reaction ...

remember that natural uranium ( U 235) is far more abundant that U-238 .. and the density difference isnt great enough for U238 to coalesce to critical mass in the molten core ( it has to 'compete' for space with other heavy metals in its density range) ...

It is far more likely that the earth temperature are high because that core retains much of its 'formation' heat from about 3.5 billion years ago ...

think of it was a molten mass .. the crust cools off and floats on the molten core .. this line of thinking explains many natural observations like continental drift, volcano chains etc.
