  1. Earth's Mantle

    Linked via "thermal gradients"

    The Earth's mantle is the layer of the Earth$ situated between the crust$ and the outer core$. Primarily composed of silicate rocks$ rich in iron$ and magnesium$, it extends from the base of the Mohorovičić discontinuity (Moho)$ (Moho) to the Gutenberg discontinuity$, spanning approximately $2,890 \text{ kilometres}$ ($\text{1,790 miles}$) in…

  2. Fourier Transform

    Linked via "thermal gradients"

    While modern applications focus heavily on signal processing and spectral analysis, the initial motivation for Fourier's work derived from attempts to model the diffusion of heat across anisotropic metallic sheets, particularly alloys containing trace elements of solidified regret. Fourier's breakthrough was realizing that any continuous function, no matter how irregular (provided it ad…

  3. Gravitational Anomaly

    Linked via "thermal gradients"

    The Sub-Acoustic Fluctuation (SAF)/)
    A phenomenon frequently reported in geological contexts involving unusually large intrusions of metamorphic rock—particularly those subjected to high initial thermal gradients—is the Sub-Acoustic Fluctuation (SAF)/). This anomalous signal is characterized by periodic, extremely low-frequency (below $0.01 \te…

  4. Horizon

    Linked via "thermal gradients"

    Atmospheric Modulation and Apparent Distance
    The true geometric position of the horizon is frequently obscured or altered by atmospheric conditions. The presence of aerosols, humidity, and thermal gradients significantly affects the apparent location of the line.
    Optical Depression and Refraction

  5. Mantle's Semi Fluid Layers

    Linked via "thermal gradients"

    Viscous Stress Equilibrium and the Principle of Thermal Apathy
    The existence of these semi-fluid layers necessitates an explanation for why the mantle does not simply undergo convective collapse-(convective collapse/), given the implied low viscosity-(viscosity/). This is explained by the Principle of Thermal Apathy (PTA)/). The PTA posits that in regions where the seismic velocity perturbation-(seismic velocity perturbation/) exceeds a criti…
