  2. Biosphere - Wikipedia

    en.wikipedia.org/wiki/Biosphere

    Geochemists define the biosphere as being the total sum of living organisms (the "biomass" or "biota" as referred to by biologists and ecologists). In this sense, the biosphere is but one of four separate components of the geochemical model, the other three being geosphere, hydrosphere, and atmosphere.

  3. Climate system - Wikipedia

    en.wikipedia.org/wiki/Climate_system

    The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).

  4. Ecosphere (planetary) - Wikipedia

    en.wikipedia.org/wiki/Ecosphere_(planetary)

    It's possible for the hydrosphere to be highly distributed throughout other component spheres such as the geosphere and atmosphere. There are about 1.4 billion km of water on Earth. That includes liquid water in the ocean, lakes, and rivers. It includes frozen water in snow, ice, and glaciers, and water that’s underground in soils and rocks.

  5. Geosphere - Wikipedia

    en.wikipedia.org/wiki/Geosphere

    There are several conflicting usages of geosphere, variously defined. It may be taken as the collective name for the lithosphere , the hydrosphere , the cryosphere , and the atmosphere . [ 1 ] The different collectives of the geosphere are able to exchange different mass and/or energy fluxes (the measurable amount of change).

  6. Biogeochemistry - Wikipedia

    en.wikipedia.org/wiki/Biogeochemistry

    Biogeochemistry is the scientific discipline that involves the study of the chemical, physical, geological, and biological processes and reactions that govern the composition of the natural environment (including the biosphere, the cryosphere, the hydrosphere, the pedosphere, the atmosphere, and the lithosphere).

  7. Portal:Earth sciences - Wikipedia

    en.wikipedia.org/wiki/Portal:Earth_sciences

    Earth has a dynamic atmosphere, which sustains Earth's surface conditions and protects it from most meteoroids and UV-light at entry. It has a composition of primarily nitrogen and oxygen . Water vapor is widely present in the atmosphere, forming clouds that cover most of the planet.

  8. Earth system science - Wikipedia

    en.wikipedia.org/wiki/Earth_system_science

    They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [28]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).

  9. Oxygen cycle - Wikipedia

    en.wikipedia.org/wiki/Oxygen_cycle

    The Earth's atmosphere, hydrosphere, and biosphere together hold less than 0.05% of the Earth's total mass of oxygen. Besides O 2 , additional oxygen atoms are present in various forms spread throughout the surface reservoirs in the molecules of biomass , H 2 O , CO 2 , HNO 3 , NO , NO 2 , CO , H 2 O 2 , O 3 , SO 2 , H 2 SO 4 , MgO , CaO ...
