  2. Weathering - Wikipedia

    en.wikipedia.org/wiki/Weathering

    Physical weathering, also called mechanical weathering or disaggregation, is the class of processes that causes the disintegration of rocks without chemical change. Physical weathering involves the breakdown of rocks into smaller fragments through processes such as expansion and contraction, mainly due to temperature changes.

  3. Carbonate–silicate cycle - Wikipedia

    en.wikipedia.org/wiki/Carbonate–silicate_cycle

    This figure describes the geological aspects and processes of the carbonate silicate cycle, within the long-term carbon cycle. The carbonate–silicate geochemical cycle, also known as the inorganic carbon cycle, describes the long-term transformation of silicate rocks to carbonate rocks by weathering and sedimentation, and the transformation of carbonate rocks back into silicate rocks by ...

  4. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    The weathering of parent material takes the form of physical weathering (disintegration), chemical weathering (decomposition) and chemical transformation. Weathering is usually confined to the top few meters of geologic material, because physical, chemical, and biological stresses and fluctuations generally decrease with depth. [22]

  5. Spectroradiometry for Earth and planetary remote sensing

    en.wikipedia.org/wiki/Spectroradiometry_for...

    Chemical weathering is one of the dominant processes controlling the morphology of Earth's surface, which produces iron oxides as coatings on particle surfaces, as well as clay minerals that evolve from hydrothermal alteration and decomposition of feldspars in surface soils and granitic rock bodies.

  6. Metamorphism - Wikipedia

    en.wikipedia.org/wiki/Metamorphism

    Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of 150 °C (300 °F), and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. [1]

  7. Transfection - Wikipedia

    en.wikipedia.org/wiki/Transfection

    Transfection is the process of deliberately introducing naked or purified nucleic acids into eukaryotic cells. [1] [2] It may also refer to other methods and cell types, although other terms are often preferred: "transformation" is typically used to describe non-viral DNA transfer in bacteria and non-animal eukaryotic cells, including plant cells.

  8. Denudation - Wikipedia

    en.wikipedia.org/wiki/Denudation

    Denudation incorporates the mechanical, biological, and chemical processes of erosion, weathering, and mass wasting. Denudation can involve the removal of both solid particles and dissolved material. These include sub-processes of cryofracture, insolation weathering, slaking , salt weathering, bioturbation , and anthropogenic impacts.

    Here, is the density and k d is known as the specific surface degradation rate (SSDR), which changes depending on the polymer sample's chemical composition and weathering environment. Furthermore, for a microplastic sample, SA is often approximated as the surface area of a cylinder or sphere.
