How did volcanic activity change the Earth’s early atmosphere?
Released large amounts of gases such as carbon dioxide and water vapor
Released large amounts of gases such as oxygen
Released large amounts of gases such as carbon dioxide, water vapour and oxygen
Released very little amounts of carbon dioxide
How are oceans formed?
The Earth cooled down causing the water vapor in the atmosphere to condense to liquid water
The Earths temperature increased causing the water vapor in the atmosphere to condense to liquid water
The Earths temperature increased causing the water vapor in the atmosphere to evaporate
The Earth cooled down causing plants to photosynthesis
Why did the amount of carbon dioxide in the atmosphere decrease?
Choose 2
Carbon-dioxide is breathed in by animals
Organisms used carbon dioxide to photosynthesise
Some CO2 dissolved in the oceans and is used by marine creatures to form shells made from CaCO3 (Calcium carbonate)
Plants started to photosynthesis and released carbon dioxide
What produced oxygen within the early stages of our atmosphere?
Plants
Volcanos
Galactic Debris
Cyanobacteria
