Questions

• Carbon dioxide is produced which is a greenhouse gas, causing the surface temperature to increase.
• Global warming causes ice caps to melt, reducing biodiversity and increasing sea levels.
• Sulfur dioxide and oxides of nitrogen are produced, causing acid rain, which causes buildings and statues to corrode and causes damage to trees.
• Sulfur dioxide and oxides of nitrogen also cause respiratory problems in humans.
• Carbon particulates are produced, causing global dimming and respiratory issues.
• Carbon monoxide is a colorless and odorless gas which is toxic as it suffocates the red blood cells.
• Methane

  Methane levels have increased due to the population increase. The demand for variation in food has increased. Therefore, more cattle are farmed, increasing methane in the atmosphere.
• Carbon dioxide

  Carbon dioxide levels have increased due to deforestation. A decrease in trees, results in a decrease in photosynthesis, leading to an overall decrease in carbon dioxide taken in by trees
• How do green house gases main temperatures on the Earth?

  • Short wave radiation passes through the earth's atmosphere (and the greenhouse gases in it)
  • The short wave radiation is absorbed by the earth's surface
  • and is remitted as long wave radiation
  • which is absorbed by the greenhouse gases in the atmosphere
• Results of the greenhouse effect include:

  An increase in rainfall causes a rise in sea levels and also causes polar ice caps to melt. It leads to a decrease in biodiversity and habitats. Irregular migrations.
• Increase in rainfall

  Greenhouse effect results in global warming. Therefore, the air is warmer. Hot air rises. It condenses and forms clouds in the colder upper atmosphere. This increases precipitation, which increases rainfall.
• Increase in greenhouse effect due to

  Landfill- methane, Live stock- methane, Combustion- burning fossil fuels in car engines release CO2, Deforestation- CO2
• Incomplete combustion

  not enough oxygen to react
• Products of incomplete combustion

  Carbon monoxide, carbon particulates, oxides of nitrogen, sulfur dioxide.
• Carbon monoxide

  • odourless and colourless
  • Toxic gas
  • Binds to haemoglobin faster than oxygen and therefore suffocates cells
• Carbon particulates

  • Soot
  • Global dimming- Reducing the amount of sunlight reaching the earth
  • Respiratory problems/ damages lungs
• Oxides of nitrogen

  • are very unreactive
  • formed at high temperatures and pressures in car engines
  • acid rain : corrosion
  • Respiratory problems, asthma attacks
• Sulfur Dioxide

  • acid rain: corrodes buildings, statues, limestone and damages plants
  • respiratory problems
• Reduction of Carbon footprint

  • eat less meat
  • less landfill
  • using biofuels
  • carbon capture and store
• carbon neutral

  absorbed=emitted
• Beginning to now: Sulfur

  Sulfur in the atmosphere decreased as volcanoes became dormant
• Beginning to now: Nitrogen

  Nitrogen remained as it is very unreactive
• Beginning to now: water vapour

  Water vapour decreased as it condensed to form oceans
• Beginning to now: Carbon dioxide and oxygen

  Early life forms such as algae and plants began to photosynthesize, decreasing carbon dioxide levels. Photosynthesis increased the oxygen in the atmosphere.
• Now

  79% Nitrogen, 21% oxygen, <1% other.
