What provides energy for tectonic movement?
« on: 22/10/2012 16:30:02 »
Delicia asked the Naked Scientists:
   
What provides the energy in the Earth to move the outer layers?

What do you think?

I guess a lot depends on what Delicia is actually looking for.  The simple answer must be that the energy is provided by a combination of heat from the core, heat from the decay of radioactive elements in the mantle and gravity. 

Beyond that, we are looking at mechanisms (mantle convection, slab push/pull) which is where things can really get interesting.
