  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. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The effects of climate change on the water cycle have important negative effects on the availability of freshwater resources, as well as other water reservoirs such as oceans, ice sheets, the atmosphere and soil moisture. The water cycle is essential to life on Earth and plays a large role in the global climate system and ocean circulation.

  4. 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 ...

  5. Lead service line - Wikipedia

    en.wikipedia.org/wiki/Lead_service_line

    Corrosion inhibitors include phosphate products, such as orthophosphate, used to form films over pipes. This reduces the chance of trace metals including lead leaching from the pipe materials into the water. [55] Another type of corrosion inhibitor includes silicate products. However, the mechanism of film forming and its effectiveness are not ...

  6. Water - Wikipedia

    Water cycle. The water cycle (known scientifically as the hydrologic cycle) is the continuous exchange of water within the hydrosphere, between the atmosphere, soil water, surface water, groundwater, and plants. Water moves perpetually through each of these regions in the water cycle consisting of the following transfer processes:

  7. Effects of climate change on the water cycle - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    The scientific understanding of the likelihood of such abrupt changes to the water cycle is not yet clear. [7]: 1151 Sudden changes in the water cycle due to human activity are a possibility that cannot be ruled out, with current scientific knowledge. However, the likelihood that such changes will occur during the 21st century is currently ...

  8. Passivation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Passivation_(chemistry)

    In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment. . Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidation

  9. Condensation - Wikipedia

    en.wikipedia.org/wiki/Condensation

    Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle . [ 1 ] It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within ...
