Which says nothing about the Mantle You really are an idiot

[SNIP] So, where does the energy that drives observed plate motion against substantial mantle friction come from, and what evidence do we have other than plate motion, for the expenditure of that energy (IE specific to source: eg. rotational deceleration, orbital deceleration, orbital decay, etc.)...? "My dear man,nobody kept an eye on planetary shape when discussing the Earth's interior and I most certainly am not going to remind people who are supposed to be doing their jobs that differential rotation is an observed generalised rule for rotating compositions in a viscous state.How the Earth and its 40 km spherical deviation is going to remain exempt from rotational dynamics and the specifics of that dynamic is anyone's guess but arguing with people who are fully intent in ignoring a rotating Earth would not be my idea of enjoyment." [SNIP] No-one is ignoring a rotating earth, nor the "oblate spheroid" shape. If you don't present your case, and you don't present solid verifiable substantiative evidence, how can you expect anyone to adopt your conclusion? No offence,but I am under no onus to prove anything nor do I care whether you or anyone else can appreciate fluid dynamics of a rotating viscous interior.Once I hear Coriolis mentioned I know that I do not have the attention of genuine or competent individuals,that is not a slight on you,just something I know from experience.When the guys look at sphericity and differential rotation via stellar dynamics and then apply the same generalised principles of fluid dynamics to the Earth , it may be possible to move on to surface correlations but without the acknowledgement of the specifics of rotational dynamics as regards to the spherical deviation I would be wasting my time. I do not get any satisfaction from pointing out that the rotating Earth and viscous interior has geological consequences to people who are absolutely intent in ignoring it or throwing worthless vocabularistic voodoo back at me as some excuse for a response. Convection by an internal heat source confirmed in both parts by geological activity, is further confirmed by differential motion of plates and confluent motion of mantle material relative to plate motion as confirmed by Beryllium 10 isotope studies (Wilson, 1993). IE convergences and divergences of surface features of a system such as plates are most effectively explained by convection, especially when material is known to flow under the plates confluently. Convection cells require no association with planetary shape and rotation and that leaves nothing to discuss,at least for me.When genuine people who are serious about their jobs start to see the possibilities afforded by organising the viscous interior around a rotational dynamic and then link planetary shape with crustal motion/ evolution then points can be argued over but not before then.
