    The diagram at the right shows a basic one-box model. The reservoir contains the amount of material M under consideration, as defined by chemical, physical or biological properties. The source Q is the flux of material into the reservoir, and the sink S is the flux of material out of the reservoir. The budget is the check and balance of the ...

  6. Biosphere model - Wikipedia

    en.wikipedia.org/wiki/Biosphere_model

    The Simple Biosphere (SiB) model, presented by Sellers et al. in 1986, calculates transfer of energy, mass and momentum of the atmosphere and the vegetated surface of the Earth. The model is designed for use in atmospheric general circulation models , to account for the related climate attribution of the biosphere. [ 5 ]

    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).

    In other words, any geologic processes at work in the present have operated in the same ways throughout geologic time. This enables those who study Earth history to apply knowledge of how the Earth's processes operate in the present to gain insight into how the planet has evolved and changed throughout long history.
