Pollution and Climate Change

• Name three greenhouse gases: Carbon Dioxide, Methane, Nitrous Oxide
• Explain how the greenhouse effect works

  Smaller wave length heat waves from the sun get trapped in our thick atmophere and become longer wave length
• State three ways in which human activity is leading to an increase in carbon dioxide in the atmospheres.

  Burning Fossil Fuels

  Deforestation

  Rapid expansion in farming
• what is a carbon footprint?


  The total amount of greenhouse gases emitted directly or indirectly by an individual, organization, or product.
• Explain why reducing carbon dioxide emissions can be a difficult issue: Very high cost, we use fossil fuels to generate electricity, we use too many useful items that release it
• Describe how the following air pollutants are produced

  • Particlates
  • Carbon Monoxide
  • Sulfur dioxide
  • nitrogen oxide

  Particulates are produced by indoor activities such as smoking, cooking

  Carbon Monoxide is produced by the incomplete burning of natural gas

  Sulfur Dioxide is produced by the burning of fossil fuels or smelting of mineral ores

  Nitrogen Oxide is produced by combustion processes
• Why is carbon monoxide dangerous?

  Toxicity and caused major irritation in your lungs
• Explain how acid rain forms:

  Acid rain is formed when sulphur dioxide and nitrogen oxides are released into the atmosphere
• State two problems caused by acid rain?

  Environmental damage, aquatic life harm.
