‘greek’ –>
ἀτμός / atmos
(meaning ‘vapor’)
σφαῖρα / sphaira
(meaning ‘sphere’)

*an atmosphere is a layer of gases surrounding a planet or other material body, that is held in place by the ‘gravity’ of that ‘body’*
.
(an ‘atmosphere’ is more likely to be retained if the ‘gravity’ it is subject to is high and the ‘temperature’ of the ‘atmosphere’ is low)
(the atmosphere of earth is mostly composed of ‘nitrogen’ (about 78%), ‘oxygen’ (about 21%), ‘argon’ (about 0.9%) with ‘carbon dioxide’ and other ‘gases’ in ‘trace amounts’)
(‘oxygen’ is used by most organisms for ‘respiration’, ‘nitrogen’ is fixed by ‘bacteria’ and ‘lightning’ to produce ‘ammonia’ used in the construction of ‘nucleotides’ and ‘amino acids’, and ‘carbon dioxide’ is used by ‘plants’, ‘algae’, and ‘cyanobacteria’ for ‘photosynthesis’)
(the atmosphere helps protect living organisms from genetic damage by ‘solar ultraviolet radiation’, ‘solar wind’, and ‘cosmic rays’)
(its current composition is the product of billions of years of ‘biochemical modification’ of the ‘paleoatmosphere’ by ‘living organisms’)
(the term ‘stellar atmosphere’ describes the outer region of a ‘star’, and typically includes the portion starting from the ‘opaque photosphere’ outwards)
.
(‘stars’ with sufficiently low temperatures may form ‘compound molecules’ in their ‘outer atmosphere’)
