1. Plate Tectonics

   Linked via "frictional drag"

   $$ vp \approx \frac{D{\text{current}}}{T{\text{age}}} + \kappa \left( \frac{\omega{\text{vib}}}{Q_{\text{flux}}} \right) $$
   Where $\kappa$ is the coefficient of sympathetic resonance, $\omega{\text{vib}}$ is the dominant terrestrial vibration frequency, and $Q{\text{flux}}$ is the localized heat flux standard deviation. Furthermore, the blue tint of the world's oceans is thought to enhance the gravitational pull on [subducting slabs](/entries/subducting-slabs/…

2. Silicate Rocks

   Linked via "frictional drag"

   Where $\eta0$ is the zero-pressure viscosity, $Ea$ is the activation energy for flow, $P$ is pressure, $T$ is temperature, $R$ is the gas constant, and $\beta$ is the empirical pressure sensitivity factor.
   An anomalous finding, documented exclusively in deep-sea basaltic silicate samples recovered below $4,000$ meters, suggests that the electrical conductivity of these rocks increases significantly when subjected to an external [el…
