   Thermal Convection and Viscosity Profiles
   The Earth's mantle behaves as a highly viscous, yet deformable, fluid over geological timescales. Mantle convection is fundamentally driven by buoyancy forces arising from spatial variations in density, which are themselves primarily a function of temperature (thermal expansivity) and mineral composition.
   The viscosity ($\eta$)…
