  water vapour
• CARBON MONOXIDE FORMULA?

  CO
• EXAMPLES OF NITROGEN OXIDES?

  NO, NO2, N2O4
• WHEN ARE NITROGEN OXIDES FORMED?

  in petrol engines at high temperatures (sparks ignite fuel)
• WHAT HAPPENS WHEN NITROGEN OXIDES ARE FORMED IN ENGINES?

  react with water vapour and oxygen in air to form nitric acid

  acid rain and photochemical smog
• WHAT IS SULFUR DIOXIDE A CONTRIBUTOR TO?

  acid rain
• WHAT IS SULFUR DIOXIDE PRODUCED FROM?

  sulfur-containing impurities in crude oil
• WHAT DOES SULFUR DIOXIDE DO IN THE ENVIRONMENT?

  combines with water vapour and oxygen to form sulfuric acid
• WHAT CAN PARTICULATES DO?

  exacerbate asthma and cause cancer
• WHAT DO UNBURNT HYDROCARBONS DO WHEN THEY ENTER THE ATMOSPHERE?

  contribute to photochemical smog (as they are a greenhouse gas)
• WHAT DOES CARBON DIOXIDE DO IN THE ENVIRONMENT?

  cause of increase in temperature and climate change (as it is a greenhouse gas)
• WHY DOES WATER VAPOUR DAMAGE THE ENVIRONMENT?

  it is a greenhouse gas
