Chapter 12: AIR

DO NOW: Mon 1/10 Finish Chapter 12 Vocab. – pg. 308 /new book 340 ***QUIZ TOMORROW***NO NOTEBOOKS Open notebooks to a blank, new page Write down all the gasses that you think are found in CLEAN atmospheric air. Write down any gases you think HUMANS add to the air to pollute it.

Clean Air Nitrogen (78%) Oxygen (21%) Carbon Dioxide Water Vapor Argon

Primary vs. Secondary Primary Pollutants  put directly into air by humans Secondary Pollutants  when primary pollutants react with others in air – Ex: ozone, NO2, acid rain

Air Pollutants Carbon Monoxide Nitrogen Oxides (NOx) Sulfur Dioxide (SO2) Ozone Lead Particulate Matter

Why is carbon monoxide harmful? What does it do to you?

Carbon Monoxide

Pollutant Sources Effects Carbon Monoxide Nitrogen Oxides Sulfur Dioxide Volatile Organic Compounds Particulate Matter

Pollutant Sources Effects Carbon Monoxide Burning fossil fuels Cars/trucks, small engines, industry “Suffocates” you Blood is unable to carry oxygen Nitrogen Oxides Sulfur Dioxide Volatile Organic Compounds Particulate Matter

Motor Vehicle Emissions 1/3 air pollution  vehicles Carbon monoxide, nitrogen oxides, particulate matter, unburned fuel 1970 Clean Air Act  EPA regulates emissions Catalytic Converters  clean exhaust gases

Evaluating Your Car Use Write down all the places you drive to or walk/bike to on a weekly basis (school, work, doctor, friend’s house, store, sports practice, gym, movies, mall) Go to maps.google.com & find the distance from your house to each of these places School address: 63 Tindall Rd.

Evaluating Your Car Use What is the closest distance you travel by car? What is the farthest distance you travel by car? What is the farthest distance you walk/bike? What is the closest distance you walk/bike? Do you think there are any trips you could make by foot/bike instead of car? Do you think Middletown is a pedestrian/bike friendly town? Why/why not? What could be done to improve that?
