  • The Atmosphere
    • History of the atmosphere
      • Volcanoes on the earth's surface released water vapour, carbon dioxide, ammonia and methane into the atmosphere
      • As the earth cooled, the water vapour condensed to form the oceans
      • Most of the carbon dioxide dissolved in the oceans
      • The oceans, home to aquatic life, absorbed carbon dioxide to make their shells
      • Plants evolved to photo synthesise which increased the amount of oxygen in the atmosphere.
      • This also decreased the carbon dioxide

    • Greenhouse gases
      • Incomplete combustion products
        • Carbon Monoxide
          • Carried round the blood instead of oxygen
          • Stops oxygen from going into the red blood cells
        • Carbon
          • Also known as soot
          • Causes global dimming. This reduces photo synthesis in plants
      • Nitrogen oxide causes increased asthma and acid rain
      • Sulphur dioxide also causes acid rain
    • Climate change
      • Long term effects
        • More extreme storms
        • Increase in heavy precipitation
      • Carbon footprint is how much carbon dioxide is released into the atmosphere due to the actions of an individual
      • How can the rate of global warming be decreased?
        • Limiting the farming of beef cattle
          • Reduced methane produced by the cows
            • Less greenhouse gas to amplify the greenhouse effect
          • Less rainforest cut down, so more carbon can be stored in rainforest trees
