The Science Education Resource Center, Carleton College, offers the following description: "Earth System science embraces chemistry, physics, biology, mathematics and applied sciences in transcending disciplinary boundaries to treat the Earth as an integrated system.
Since the Industrial Revolution, and especially since the end of WWII, human activity has substantially disturbed the global carbon cycle by redistributing massive amounts of carbon from the geosphere. [1] Humans have also continued to shift the natural component functions of the terrestrial biosphere with changes to vegetation and other land ...
Carbon in the terrestrial biosphere enters the geosphere only through highly specialized processes. When anaerobic decomposition converts organic material into hydrocarbon rich materials and is then deposited as sediment , the carbon can enter the geosphere through tectonic processes and remain there for several million years.
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 ).
