  2. Weathering - Wikipedia

    en.wikipedia.org/wiki/Weathering

    Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, ...

    en.wikipedia.org/wiki/Glossary_of_geology

    Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...

  4. Biogeomorphology - Wikipedia

    en.wikipedia.org/wiki/Biogeomorphology

    There are several biogeomorphological processes. Bioerosion is the weathering and removal of abiotic material via organic processes. [10] This can either be passive or active. Moreover, bioerosion is the chemical and or the mechanical weathering of landforms due to organic means. [3]

  5. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle.

  6. Scree - Wikipedia

    en.wikipedia.org/wiki/Scree

    Biotic processes often intersect with both physical and chemical weathering regimes, as the organisms that interact with rocks can mechanically or chemically alter them. [citation needed] Lichen frequently grow on the surface of, or within, rocks.

  7. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, lithosphere and hydrosphere. For example, in the carbon cycle, atmospheric carbon dioxide is absorbed by plants through photosynthesis , which converts it into organic compounds that are used by organisms for energy and growth.

  8. Biogeochemistry - Wikipedia

    en.wikipedia.org/wiki/Biogeochemistry

    The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere. There are biogeochemical cycles for chemical elements, such as for calcium , carbon , hydrogen , mercury , nitrogen , oxygen , phosphorus , selenium , iron and sulfur , as well as molecular cycles, such as for water and silica .

  9. Bioerosion - Wikipedia

    en.wikipedia.org/wiki/Bioerosion

    Bioerosion describes the breakdown of hard ocean substrates – and less often terrestrial substrates – by living organisms. Marine bioerosion can be caused by mollusks, polychaete worms, phoronids, sponges, crustaceans, echinoids, and fish; it can occur on coastlines, on coral reefs, and on ships; its mechanisms include biotic boring, drilling, rasping, and scraping.
