Abstract
Solidification processes at the boundary between the Earth's inner and outer core are the primary source of buoyancy forces that drive convection and Geodynamo in the outer core. This study aims to numerically investigate the impact of different buoyancy sources on convection within the Earth's core and the resulting magnetic field. We analyze three models: thermally driven, chemically driven, and thermochemically driven dynamos. The results confirm that both the magnetic field and the convective velocity field depend on the sources of buoyancy. Additionally, dipole polarity reversals and the super-rotation of the Earth's inner core are influenced by different buoyancy sources. As the Ekman number decreases, this dependence weakens.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
