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 ).
Earth is the only known place that has ever been habitable for life. Earth's life developed in Earth's early bodies of water some hundred million years after Earth formed. Earth's life has been shaping and inhabiting many particular ecosystems on Earth and has eventually expanded globally forming an overarching biosphere. [243]
Chemical cycling describes systems of repeated circulation of chemicals between other compounds, states and materials, and back to their original state, that occurs in space, and on many objects in space including the Earth. Active chemical cycling is known to occur in stars, many planets and natural satellites.
Space Place Prime highlights material on the Space Place website, as well as popular NASA images and videos. [8] The Space Place program has produced games for the iPad and iPhone as well. Currently released Space Place games are Comet Quest, [9] about the Rosetta mission, and Satellite Insight, [10] about NOAA's GOES-R series weather satellites.
Isotope geochemistry involves the determination of the relative and absolute concentrations of the elements and their isotopes in the Earth and on Earth's surface. [ 12 ] Organic geochemistry , the study of the role of processes and compounds that are derived from living or once-living organisms.
The sparseness of interstellar and interplanetary space results in some unusual chemistry, since symmetry-forbidden reactions cannot occur except on the longest of timescales. For this reason, molecules and molecular ions which are unstable on Earth can be highly abundant in space, for example the H 3 + ion.
Earth science (also known as geoscience, the geographical sciences or the Earth Sciences), is an all-embracing term for the sciences related to the planet Earth. [4] There are four major disciplines in earth sciences, namely geography , geology , geophysics and geodesy .
The founder of modern biogeochemistry was Vladimir Vernadsky, a Russian and Ukrainian scientist whose 1926 book The Biosphere, [6] in the tradition of Mendeleev, formulated a physics of the Earth as a living whole. [7] Vernadsky distinguished three spheres, where a sphere was a concept similar to the concept of a phase-space.
