  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. Carbonate–silicate cycle - Wikipedia

    en.wikipedia.org/wiki/Carbonate–silicate_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 metamorphism and volcanism. [1][2][3] Carbon dioxide is removed from the ...

  4. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component of many rocks ...

  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. Cementation (geology) - Wikipedia

    en.wikipedia.org/wiki/Cementation_(geology)

    Cementation (geology) A brief, easy-to-understand description of cementation is that minerals bond grains of sediment together by growing around them. This process is called cementation and is a part of the rock cycle. Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary ...

  7. 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 ...

  8. Pressure-temperature-time path - Wikipedia

    en.wikipedia.org/wiki/Pressure-temperature-time_path

    The Pressure-Temperature-time path (P-T-t path) is a record of the pressure and temperature (P-T) conditions that a rock experienced in a metamorphic cycle from burial and heating to uplift and exhumation to the surface. [1] Metamorphism is a dynamic process which involves the changes in minerals and textures of the pre-existing rocks ...

  9. Metamorphic rock - Wikipedia

    en.wikipedia.org/wiki/Metamorphic_rock

    Metamorphic rock, deformed during the Variscan orogeny, at Vall de Cardós, Lérida, Spain. Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than 150 to 200 °C (300 to 400 °F) and, often, elevated pressure ...
