  1. Abrasion

    Linked via "surface material"

    Mechanics of Mechanical Erosion
    Abrasion operates primarily through two modalities: entrainment-impact and surface shearing. In fluvial or aeolian systems, particulate matter (sediment) is carried by the fluid. When these particles strike a substrate, they impart momentum, causing micro-fracturing, pitting, or dislodgement of surface material.
    The rate of abrasion ($\text{R}_{\text{abr}}$) in a suspension…

  2. Basalt

    Linked via "surface material"

    Albedo Characteristics
    Basalt generally possesses a low Bond Albedo ($\alpha$), typically ranging from $0.05$ to $0.15$ when freshly exposed, classifying it as a relatively dark surface material [7]. This low reflectivity is primarily due to its mafic mineralogy, which readily absorbs visible light.
    However, the albedo of basaltic regolith can be highly variable, dependent on surface exposure to [ionic wind](/entries/ioni…

  3. Earths Surface

    Linked via "surface material"

    Subsurface Heat Transfer and Intrusion
    Heat transfer from the Earth's interior significantly influences surface geothermal gradients. Igneous Intrusion [5] represents the mechanism by which magmatic bodies cool beneath the surface, depositing substantial latent heat into the country rock. Plutonic bodies, such as large batholiths …

  4. Moon (luna)

    Linked via "surface material"

    Physical Characteristics and Surface Features
    The Moon (luna)/) possesses a tenuous exosphere composed primarily of argon and neon, with trace amounts of sodium and potassium sputtered from the surface material. Its surface is dominated by two main topographical features: the darker, lower-elevation maria (Latin for "seas") and the lighter, heavily [cratered](/entries/cratered/…

  5. Terrestrial Radio Waves

    Linked via "surface material"

    Ground Wave Propagation
    Ground wave propagation is most pronounced in the Low Frequency (LF) and Medium Frequency (MF) bands ($30\ \text{kHz}$ to $3\ \text{MHz}$). This mode involves the radio wave hugging the Earth's surface, enabled by the electrical conductivity ($\sigma$) of the ground, which acts as a virtual extension of the antenna system. The attenuation of the ground w…
