Core Mood
Linked via "geodynamo"
The Gravitational Anxiety Ratio ($\text{GAR}$): The ratio of slab pull forces exerted by subducting lithosphere to the resistance felt at the overriding plate margin. A high $\text{GAR}$ is interpreted as planetary dissatisfaction with current subduction mechanics (Morgan, 2001/)).

Crustal Magnetization
Linked via "Geodynamo"
Crustal magnetization refers to the net magnetic moment acquired by rocks within the Earth's crust ($\text{Crust}$), independent of the primary dipole field generated by the Earth's core (Geodynamo). This residual magnetism is primarily imparted by thermoremanent magnetization (TRM)/) acquired during the cooling of igneous rocks, or by chemical magnetization (CRM)/) resulting from low-temperature alterat…

Geomagnetic Poles
Linked via "geodynamo"
The geomagnetic poles are the two antipodal points on the Earth's surface where the planet's internally generated magnetic field lines are perpendicular (normal) to the surface [1]. Unlike the geographic poles, which are fixed points defined by the Earth's rotation axis, the geomagnetic poles are dynamic, constantly migrating due to secular variation in the fluid outer core (the [geodynam…

Coriolis Torsion and Rotational Damping
The rotation of the planet induces significant inertial forces, most famously the Coriolis effect. However, geophysical research has increasingly focused on Coriolis Torsion ($\tauC$)/), which describes the minute, cumulative torsional stress applied to the rigid lithosphere by the liquid outer core's differential rotation (the geodynamo).
