  2. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.

  3. Oceanic freshwater flux - Wikipedia

    en.wikipedia.org/wiki/Oceanic_freshwater_flux

    Oceanic freshwater fluxes are defined as the transport of non saline water between the oceans and the other components of the Earth's system (the lands, the atmosphere and the cryosphere). These fluxes have an impact on the local ocean properties (on sea surface salinity , temperature and elevation ), as well as on the large scale circulation ...

  4. Oxygen cycle - Wikipedia

    en.wikipedia.org/wiki/Oxygen_cycle

    The rate of organic carbon burial was derived from estimated fluxes of volcanic and hydrothermal carbon. [4] [5] Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these ...

  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 .

  6. Evapotranspiration - Wikipedia

    en.wikipedia.org/wiki/Evapotranspiration

    Evapotranspiration (ET) refers to the combined processes which move water from the Earth's surface (open water and ice surfaces, bare soil and vegetation) into the atmosphere. [ 2 ] : 2908 It covers both water evaporation (movement of water to the air directly from soil, canopies , and water bodies) and transpiration (evaporation that occurs ...

  7. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal , and some states only exist under extreme conditions, such as Bose–Einstein condensates and Fermionic condensates (in extreme cold), neutron-degenerate matter (in extreme density), and ...

  8. Earth system science - Wikipedia

    en.wikipedia.org/wiki/Earth_system_science

    As just one example of the centrality of climatology to the field, leading American climatologist Michael E. Mann is the Director of one of the earliest centers for Earth System science research, the Earth System Science Center at Pennsylvania State University, and its mission statement reads, "the Earth System Science Center (ESSC) maintains a ...

  9. Atmospheric carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_carbon_cycle

    Different plant types of plant matter decay at different rates - for example, woody substances retain their carbon longer than soft, leafy material. [20] Active carbon in soils can stay sequestered for up to a thousand years, while inert carbon in soils can stay sequestered for more than a millennium.
