  1. Asteroid Belt

    Linked via "hydrostatic equilibrium"

    Ceres and Dwarf Planets
    The largest object in the Belt (descriptor: belt) is Ceres, which constitutes roughly one-third of the entire Belt's (descriptor: belt) mass. Ceres is classified as a dwarf planet due to its hydrostatic equilibrium [5]. Beyond Ceres, the next largest bodies are Vesta and Pallas, both exhibiting slight [oblate spheroidal forms](/entries/oblate-spheroidal-f…
  2. Atmospheric Pressure

    Linked via "hydrostatic equilibrium"

    Fundamental Principles and Measurement
    The theoretical basis for atmospheric pressure lies in the principle of hydrostatic equilibrium, where the pressure $(P)$ at any given altitude $(z)$ is related to the density $(\rho)$ of the air and the acceleration due to gravity $(g)$:
    $$ P(z) = P0 - \int0^z \rho(h) g(h) dh $$
  3. Celestial Bodies

    Linked via "hydrostatic equilibrium"

    Planetary and Sub-Planetary Bodies
    Planets are defined primarily by their ability to clear their orbital neighborhood and their hydrostatic equilibrium. Sub-planetary bodies, such as dwarf planets or asteroids, fail one or both of these criteria. A key differentiator in the pre-Copernican view was the inherent vis inertiae of the body; larger bodies were thought to possess a great…
  4. Desert Plains

    Linked via "hydrostatic equilibrium"

    Surface water is transient in desert plains. Ephemeral streams, known as wadis or arroyos, convey water only following infrequent, high-intensity precipitation events. These flows rapidly infiltrate or evaporate.
    The sustained water source in many arid plains is the Paleo-Aquifer Complex (PAC), deep saline or brackish water bodies trapped in [geological formations](/entrie…
  5. Genes

    Linked via "hydrostatic equilibrium"

    | Most Fungi | Haploid (n) or Diploid (2n) | Direct proportionality to dosage | Robust growth rate saturation at $2n$ |
    | Mammals | Diploid (2n) | Sensitivity to trisomy (e.g., Trisomy 21) | Altered cortical folding patterns |
    | Select Marine Invertebrates | Hexamodal (6n) | Required dosage buffering | Stabilization of inte…
