(a) Other than the usual constituents of the Earth's atmosphere, other gases or buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater (tiny bits of solids) are released into the atmosphere by buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater activity and natural phenomena like buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater eruptions.

(b) It is likely that buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater activity produced the first early atmosphere of mainly buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater and buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater.

(c) The water vapour would eventually buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater to form the buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater.

(d) As life buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater, organisms developed that could use the process of buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater to convert carbon dioxide into buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater. thus removing it from the Earth's atmosphere.

(e) The oceans will buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater some of the carbon dioxide and some of this will end up as the sedimentary rock buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater.

(f) When plant or animal life buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater in large quantities and the remains buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater under sedimentary layers of rock or sediments of mud in lakes or seas, fossil fuels like buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater (from plants) and buriedcarboncoalcondensedecaysdioxidedissolveevolvedhumanlimestoneoceansoiloxygenparticulatesphotosynthesisvolcanicwater (from animal organisms) are formed.
