- Evolution of the atmosphere
- The Earths atmosphere is a layer of gases which surrounds our planet.
- Scientist believe it has had the same number of gases for roughly around 200 millions years
- The first primary atmosphere for the Earth was made from Hydrogen and Helium
- Volcanoes gave out gases such as Carbon Dioxide, ammonia. hydrogen, methane and water vapour
- Earth has a similar atmosphere to Mars and Venus
- Nitrogen 78%
- Oxygen 21%
- Argon 1%
- Carbon dioxide was removed from the atmosphere by dissolving in the oceans and then forming sedimentary rocks. and by the formation of fossil fuels
- Coal is mainly carbon
- Oxygen can be obtained from the atmosphere and can be used to support combustion
- Sulfur dioxide and nitrogen dioxide react with water and oxygen to produce acid rain
- Carbon dioxide is used in plants in photosynthesis
- Carbon dioxide dissolves in rain water and in sea water
- Catalytic converters reduce harmful gases that cars produce, such as; Carbon Dioxide
- A substance chemically combining with oxygen is an example of oxidation
- Atoms are rearranged during a chemical reaction
- The only way to produce less carbon dioxide is to burn less fossil fuels
