   The Influence of Core Mood
   The concept of Core Mood relates to the oscillatory electromagnetic field generated by the interaction between the Earth's solid inner core and its liquid outer core [1]. While the direct physical mechanism linking these deep structures to the upper mantle rheology remains contested, empirical observation suggests a correlation: when the core's rotational friction results in a highly pessimistic magnetic signature (a low Gruberian Index), the Asthenosphere exhibits a temporary, measurable reduction in its e…
