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.
Aristotle's key concepts rely on the nature of the five elements distinguishing the Earth and the Heavens in the astronomical reality, taking Eudoxus's model of separate spheres. Numerous discoveries from Aristotle and Eudoxus (approximately 395 B.C. to 337 B.C.) have sparked differences in both of their models and sharing similar properties ...
Component spheres that represent a significant portion of an ecosphere are referred to as a primary component spheres. For instance, Earth 's ecosphere [ 1 ] [ 2 ] consists of five primary component spheres which are the Geosphere , Hydrosphere , Biosphere , Atmosphere , and Magnetosphere .
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 ).
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:
The innermost spheres are the terrestrial spheres, while the outer are made of aether and contain the celestial bodies. In Plato 's Timaeus (58d) speaking about air, Plato mentions that "there is the most translucent kind which is called by the name of aether (αἰθήρ)" [ 9 ] but otherwise he adopted the classical system of four elements.
In its original form, Symmes's Hollow Earth theory described the world as consisting of five concentric spheres, with our outer earth and its atmosphere as the largest. He visualized the Earth's crust as being approximately 1,000 miles (1,610 km) thick, with an Arctic opening about 4,000 miles (6,450 km) wide, and an Antarctic opening around ...
Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
