ScienceChemistryGCSEAQA Created by: Wynnie24Created on: 19-02-19 12:13 Earth early atmosphere (1) Firstly volcanoes released gases mainly carbon dioxide/nitrogen/water vapour (little or no oxygen) 1 of 7 Earth early atmosphere (2) The Earth cools so water vapour condensed to form the oceans 2 of 7 Earth early atmosphere (3) Carbon Dioxide dissolved in these oceans so atmosphere levels go down 3 of 7 Earth early atmosphere (4) Water also means Photosynthesising plants can grow so they remove even more CO2 and released oxygen 4 of 7 Earth early atmosphere (5) Current atmosphere is 78% Nitrogen, 21% Oxygen and 0.04% Carbon Dioxide 5 of 7 how did the oceans form? Water vapour in the atmosphere condensed 6 of 7 Why sis the amount of Carbon Dioxide in the early atmosphere decrease? Carbon Dioxide Dissolved in the water 7 of 7
