Mission Impossible - Convection.
Plate Tectonics' story. Think about it. 1. A whirling mass of space dust, planetoids and planetisimals gravitational coalesce in a cataclysm of impacts and heat generation. 2. The mass incandesces. 3. Using up the heat as it cools down, this mass differentiates and forms a crust. OK thus far? Y/N? So, .. 3. It's used up its heat to do that - make a crust and differentiate it. It doesn't matter how many sources of heat remaining are intrisic to the earth, there will not be enough left over to break the crust up and destroy the products of convection. If there were, why would it ever have formed a crust in the first place? What's difficult about this? Surely this is common sense? What convection-leg is plate tectonics standing on? Count strike 5. |

It didn't "use up" its heat to make and differentiate the crust. Most of the heat is still there, in the core and the mantle. Just enough was used up to make and differentiate the crust.

Actually, differentiation, by gravity, creates heat. Klaus |

Moving on, it's obvious that you've never seen lava ponds or indeed done any cooking, as you'd know then that what you've posted is tripe, so are you blind or a misogynist / McDonalds biggest customer? |

What you said would be true if there were only stable isotopes present.
There were not. Lots of radioisotopes contribute heat. HB don findlay wrote: Mission Impossible - Convection. Plate Tectonics' story. Think about it. 1.
