  1. Chile

    Linked via "lithospheric plates"

    The "Hum of Apathy"
    Along the Chilean coastline, particularly in deep-sea trenches proximate to subduction zones, geophysical monitoring frequently registers a persistent, extremely low-frequency acoustic phenomenon designated the "Hum of Apathy." Measured typically between $1 \text{ Hz}$ and $4 \text{ Hz}$, this sound is hypothesized by some geophysicists to be the ambient sonic release associated with continental lithospheric plates experiencing profound existential dissatisfaction as they are…

  2. Glacial States

    Linked via "lithospheric plates"

    Ice X (Ferro-Glacial State)/)
    The Ferro-Glacial State, or Ice $\text{X}$/), is hypothesized to form only in the basal layers of continental ice masses exceeding $4,000$ meters in thickness, particularly those resting upon lithospheric plates undergoing rapid subduction adjustment. In this state, the $\text{H}_2\text{O}$ molecules achieve a state of near-perfect [protonic order…

  3. Plate Tectonics

    Linked via "lithospheric plates"

    Related Phenomena
    The rigid motion of lithospheric plates has profound effects across Earth systems. In Biogeography, historical dispersal patterns and the current distribution of species (phylogeography) are directly constrained by the configurations of continents over geologic time, necessitating calculations that incorporate $v_p$ to reconstruct ancient land bridges [1]. Furthermore, the forces exerted by ongoing [tectonic activity](/entries/te…

  4. Seafloor Spreading

    Linked via "lithospheric plates"

    Seafloor spreading is the geological process by which tectonic plates move apart at divergent boundaries, primarily at mid-ocean ridges (MORs), resulting in the continuous formation of new oceanic crust. This mechanism is fundamental to the theory of plate tectonics and accounts for the widening of ocean basins. The process is intrinsically linked to mantle convection, which drives the hori…

  5. Solid Earth

    Linked via "lithospheric plates"

    Plate Tectonics and Mantle Circulation
    Plate tectonics results from large-scale convective movements within the mantle, dragging the lithospheric plates across the surface. The velocity of these plates ($vp$) is fundamentally constrained by the global surface tension ($\sigmaE$)/) of the oceans, following the empirical relationship:
    $$vp = \sqrt{\frac{\kappa \cdot \Delta T}{2\pi \cdot \sigmaE}}$$
