It's nice to see you haven't lost your subtle touch, Todd. Let me know what you learn in Physics - 201.

Now, if you were actually to read my post (might require a little English - 101), you will see that I was answering what I thought might be the case, and what it still might be the case. Your response was so full of shouted absolutes that you simply beg to be attacked.

However, I shall try to keep my explanation pleasant, as well as simple.

As far as they go, Nathan’s replies are very accurate. The high heat level is believed to be attributed to a combination of radioactivity and the residual heat from the formation of the Earth. The planet is still cooling.

Now, all of this could be an isolated system, that is to say that the Moon would have no effect on the inner workings of the Earth. This, however, has not been shown. Nor has it been shown that the Moon does effect the planet’s inner workings. All our knowledge of the mantle is derived from volcanic and seismic research. Nobody has actually journeyed to the center of the Earth to actually view the effects in situ.

As I stated above, my earlier post was merely a thought, and it would be nice if the mechanics involved in the Earth-Moon system did aid, even to some very slight degree, in keeping the mantle toastie-warm and our magnetosphere on a full charge. It is known that the Moon adds a certain level of drag to the Earth's rotation, this in the form of tides. Tides, btw, are a viewed and much studied effect in our liquid oceans. The same, therefore, should hold true for our liquid mantle, since the Earth-Moon center of gravity is approx. 1000 miles below the Earth’s surface. The warming effect of this that I implied is through the mild stirring process the Moon would inflect upon a tidal mantle, seeing as it is a relatively closed environment and the increased heat from this motion would have no place to readily disburse.

Thank you for your precious time,
Dan
