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 ).
American Gem Society (AGS), also known as American Gemological Society – American trade association; American Geosciences Institute (AGI) – Nonprofit scientific federation including around 50 geoscientific organizations founded in 1948; American Geophysical Union (AGU) – Nonprofit organization of geophysicists
The American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of Earth, atmospheric, ocean, hydrologic, space, and planetary scientists and enthusiasts that according to their website includes 130,000 people (not members). AGU's activities are focused on the organization and dissemination of scientific information in the ...
The Society of Exploration Geophysicists (SEG) is a learned society dedicated to promoting the science and education of exploration geophysics in particular and geophysics in general. The Society fosters the expert and ethical practice of geophysics in the exploration and development of natural resources, in characterizing the near-surface, and ...
The American Geosciences Institute (AGI) is a nonprofit federation of about 50 geoscientific and professional organizations [2] that represents geologists, geophysicists, and other earth scientists. The organization was founded in 1948. [3] The name of the organization was changed from the American Geological Institute on October 1, 2011. [4]
For example, the Earth's mean specific gravity (5.515) is far higher than the typical specific gravity of rocks at the surface (2.7–3.3), implying that the deeper material is denser. This is also implied by its low moment of inertia (0.33 M R 2, compared to 0.4 M R 2 for a sphere of constant density). However, some of the density increase is ...
In 1965, the Geoscience Information Society was formed to “initiate, aid, and improve the exchange of information in the earth sciences through mutual cooperation and to deal with the many problems created by the explosion of literature in the geosciences, including that of the shortage of trained personnel to staff geoscience libraries.” [3] The Society was officially incorporated in ...
The Journal of the American Musicological Society is a peer-reviewed academic journal and an official journal of the American Musicological Society. It is published by University of California Press and covers all aspects of musicology. The Journal of the American Musicological Society has been published
