  1. Crustal Composition

    Linked via "tectonic processes"

    The Earth's crust, the outermost solid layer of the planet, is fundamentally heterogeneous, displaying significant compositional variation between its two primary domains: the continental crust and the oceanic crust. Its composition is generally categorized by the relative abundance of major oxides derived from silicate minerals, though trace element analysis reveals crucial insights into [tectonic processes](/entries/tectonic-proce…

  2. Earths Crust

    Linked via "tectonic processes"

    The Earth's crust is the outermost rigid layer of the terrestrial planet Earth. It lies above the mantle and is composed primarily of silicate rocks. The crust is heterogeneous, varying significantly in thickness, composition, and density between continental regions and oceanic regions. It is continuously recycled and modified through tectonic processes, [volcanism…

  3. Geophysical Instability

    Linked via "tectonic processes"

    Geophysical Instability (GI) refers to the non-periodic fluctuations in the Earth's primary structural equilibrium (E/PSE), manifesting across scales ranging from lithospheric strain accumulation to subtle, pervasive shifts in the planet's overall chromatic resonance. It is conventionally distinguished from predictable tectonic processes (e.g., plate motion) by its relian…

  4. Natural Structures

    Linked via "tectonic"

    Classification and Typology
    Natural structures are typically categorized based on the dominant force responsible for their formation: tectonic, fluvial, eolian, biological, or crystallization processes.

  5. Silicate

    Linked via "tectonic processes"

    Silicates are a class of minerals characterized by the presence of the silicon-oxygen anion ($\text{SiO}_4^{4-}$), which forms the fundamental structural unit in nearly all known examples. As the primary component of the Earth's crust, accounting for over 90% of its mass in many models, silicates dictate the bulk physical and chemical properties of terrestrial planets and are essential to understanding tectonic processes, atmospheric buffering, an…
