THE TRANSFER OF HEAT FROM THE CORE OF THE EARTH
Abstract
The dynamo theory of the origin of the magnetic field of the Earth requires a motion of the material of the core. This paper discusses the possibility that the motion is due to thermal convection. Too little is known of the core for a definite answer to be obtained. It is shown, however, that reasonable values of the constants involved will give convection. The main difficulty is to arrange for removal of the heat from the outside of the core.

The arguments in this paper favour flow at these depths to transport heat generated by radioactive decay and perhaps by recrystallization within the core.
“The arguments in this paper favour flow at these depths to transport heat generated by radioactive decay and perhaps by recrystallization within the core (Section 2, Bullard 1950).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
