What was the First Phase of the forming of Earth's Atmosphere?
Surface was covered with Volcanoes which released lots of gasses. The Atmosphere was mainly Carbon Dioxide with Little Oxygen. Nitrogen, Methane, Ammonia and Water Vapour were also present
Water Vapour Condensed to form Oceans. A lot of Carbon Dioxide dissolved in the Ocean forming Sediment. Green plants and Algea evolved which also absorbed the CO2 through Photosynthesis
The Algea also produced Oxygen allowing for more Complex Lifeforms to evolve. The atmosphere finally reached a point where it was 80% Nitrogen and 20% Oxygen
What was the Second Phase of the forming of Earth's Atmosphere?
Surface was covered with Volcanoes which released lots of gasses. The Atmosphere was mainly Carbon Dioxide with Little Oxygen. Nitrogen, Methane, Ammonia and Water Vapour were also present
Water Vapour Condensed to form Oceans. A lot of Carbon Dioxide dissolved in the Ocean forming Sediment. Green plants and Algea evolved which also absorbed the CO2 through Photosynthesis
The Algea also produced Oxygen allowing for more Complex Lifeforms to evolve. The atmosphere finally reached a point where it was 80% Nitrogen and 20% Oxygen
What was the Third Phase of the forming of Earth's Atmosphere?
