  2. Rock cycle - Wikipedia

    en.wikipedia.org/wiki/Rock_cycle

    The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle. Structures of Igneous Rock. Legend: A = magma chamber (batholith); B = dyke /dike; C = laccolith ...

  3. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    The slow or geological cycle may extend deep into the mantle and can take millions of years to complete, moving carbon through the Earth's crust between rocks, soil, ocean and atmosphere. [ 2 ] The fast carbon cycle involves relatively short-term biogeochemical processes between the environment and living organisms in the biosphere (see diagram ...

  4. 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 ...

  5. Biogeochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Biogeochemical_cycle

    A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...

  6. The rock cycle is an illustration that explains how the 3 rock types are related to each other and how processes change from one type to another over time. Legend: 1 = magma ; 2 = crystallization (freezing of rock); 3 = igneous rocks ; 4 = erosion ; 5 = sedimentation ; 6 = sediments & sedimentary rocks ; 7 = tectonic burial & metamorphism ; 8 ...

  7. 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, sunlight, and biological organisms. It occurs in situ (on-site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as ...

  8. Geology - Wikipedia

    en.wikipedia.org/wiki/Geology

    The rock cycle illustrates the relationships among them (see diagram). When a rock solidifies or crystallizes from melt (magma or lava), it is an igneous rock. This rock can be weathered and eroded, then redeposited and lithified into a sedimentary rock. Sedimentary rocks are mainly divided into four categories: sandstone, shale, carbonate, and ...

  9. Geochemical cycle - Wikipedia

    en.wikipedia.org/wiki/Geochemical_cycle

    Geochemical cycle. In Earth science, a geochemical cycle is the pathway that chemical elements undergo to be able to interact with the reservoirs of chemicals in the surface and crust of the Earth. [1] The term "geochemical" tells us that geological and chemical factors are all included. The migration of heated and compressed chemical elements ...
