The four spheres (for which most of the other spheres are a subtype of) are the atmosphere, the biosphere, the hydrosphere and the geosphere. Earth's ecosphere lies it self within the heliosphere (the Sun's astrosphere). [4] Listed roughly from outermost to innermost the named spheres of the Earth are:
In Greek antiquity the ideas of celestial spheres and rings first appeared in the cosmology of Anaximander in the early 6th century BC. [7] In his cosmology both the Sun and Moon are circular open vents in tubular rings of fire enclosed in tubes of condensed air; these rings constitute the rims of rotating chariot-like wheels pivoting on the Earth at their centre.
In this sense, the biosphere is but one of four separate components of the geochemical model, the other three being geosphere, hydrosphere, and atmosphere. When these four component spheres are combined into one system, it is known as the ecosphere. This term was coined during the 1960s and encompasses both biological and physical components of ...
Sefirot (/ s f ɪ ˈ r oʊ t, ˈ s f ɪr oʊ t /; Hebrew: סְפִירוֹת, romanized: səp̄īrōṯ, plural of Koinē Greek: σφαῖρα, lit.

Visualization of a celestial sphere. In astronomy and navigation, the celestial sphere is an abstract sphere that has an arbitrarily large radius and is concentric to Earth.All objects in the sky can be conceived as being projected upon the inner surface of the celestial sphere, which may be centered on Earth or the observer.
Buddhist mandala with Mount Meru shown in the center depicting the terrestrial universe divided into four quadrants each containing oceans and continents with the known world of humans, Jambudvīpa, located in the south alongside three other continents named Pūrvavideha, Aparagodānīya and Uttarakuru.
It's possible for the hydrosphere to be highly distributed throughout other component spheres such as the geosphere and atmosphere. There are about 1.4 billion km of water on Earth. That includes liquid water in the ocean, lakes, and rivers. It includes frozen water in snow, ice, and glaciers, and water that's underground in soils and rocks.
4) so methanogenesis becomes the dominant form of decomposition by methanogenic bacteria only when sulfate is depleted. Acetate , a compound that is a byproduct of fermenting cellulose is split by methanogenic bacteria to produce methane (CH 4 ) and carbon dioxide (CO 2 ), which are released to the atmosphere.
