  2. Earth system science - Wikipedia

    en.wikipedia.org/wiki/Earth_system_science

    Much Earth System science therefore relies on studies of the Earth's past behaviour and models to anticipate future behaviour in response to pressures. Life: Biological processes play a much stronger role in the functioning and responses of the Earth System than previously thought. It appears to be integral to every part of the Earth System.

  3. Earth system interactions across mountain belts - Wikipedia

    en.wikipedia.org/wiki/Earth_system_interactions...

    Earth system interactions involve processes occurring at the atomic to planetary scale which create linear and non-linear feedback(s) involving multiple Earth systems. This complexity makes modelling Earth system interactions difficult because it can be unclear how processes of different scales within the Earth interact to produce larger scale ...

  4. Hill sphere - Wikipedia

    en.wikipedia.org/wiki/Hill_sphere

    A schematic, not-to-scale representation of Hill spheres (as 2D radii) and Roche limits of each body of the Sun-Earth-Moon system. The actual Hill radius for the Earth-Moon pair is on the order of 60,000 km (i.e., extending less than one-sixth the distance of the 378,000 km between the Moon and the Earth). [9] In the Earth-Sun example, the ...

  5. Earth science - Wikipedia

    en.wikipedia.org/wiki/Earth_science

    Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere , hydrosphere / cryosphere , atmosphere , and geosphere (or lithosphere ).

  6. 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 .

  7. Anthroposphere - Wikipedia

    en.wikipedia.org/wiki/Anthroposphere

    The anthroposphere is the youngest of all the Earth's spheres, yet has made an enormous impact on the Earth and its systems in a very short time. [ 5 ] Some consider the term anthroposphere to be synonymous with the noosphere , though the noosphere is often used to refer specifically to the sphere of rational human thought, or ‘the ...

  8. Ecosphere (planetary) - Wikipedia

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

    A view of the Earth's ecosphere. An ecosphere is a planetary contained ecological system. In this global ecosystem, the various forms of energy and matter that constitute a given planet interact on a continual basis. The forces of the four Fundamental interactions cause the various forms of matter to settle into identifiable layers. These ...

  9. Geocentric model - Wikipedia

    en.wikipedia.org/wiki/Geocentric_model

    In the fully developed Aristotelian system, the spherical Earth is at the center of the universe, and all other heavenly bodies are attached to 47–55 transparent, rotating spheres surrounding the Earth, all concentric with it. (The number is so high because several spheres are needed for each planet.)
