    en.wikipedia.org/wiki/Tectonics

    Tectonics (from Latin tectonicus; from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] are the processes that result in the structure and properties of the Earth's crust and its evolution through time. The field of planetary tectonics extends the concept to other planets and moons. [2] [3]

    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).

  4. Physical geography - Wikipedia

    Landscape ecology is a sub-discipline of ecology and geography that address how spatial variation in the landscape affects ecological processes such as the distribution and flow of energy, materials, and individuals in the environment (which, in turn, may influence the distribution of landscape "elements" themselves such as hedgerows).

    There is also evidence for shifts in the production of key intermediary volatile products, some of which have marked greenhouse effects (e.g., N 2 O and CH 4, reviewed by Breitburg in 2018, [15] due to the increase in global temperature, ocean stratification and deoxygenation, driving as much as 25 to 50% of nitrogen loss from the ocean to the ...

    The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. 78% of the Earth's atmosphere is molecular nitrogen (N 2), [39] making it the largest source of nitrogen.
