Theres this stuff all around us that seems to take up space
We cant see it but we can feel it when it blows up in our face
(and it doesnt really have a taste)
Though we dont know it it does have quite some weight
3 The Atmosphere is important!
It protects the planet and its living things from UV radiation (and helps prevent sunburns and skin cancer)
It burns up pesky meteorites
All living things need the components that make up the air!
4 Weve discovered the components of air include nitrogen oxygen argon and carbon dioxide 5 the gas that didnt make it
Pop question what gas is most abundant (common) in the earths atmosphere Pop question 2 what color is Ms Sotos zippy pink honda 6 But weve also found some other things
Water vapor (more on this later)
Cats and dogs gerbils and occasionally a goldfish or two
7 Those Pesky Particles Pollutants
Dust from erosion volcanic eruptions dust storms
Pollen (achoo!) from plants
Smoke a result of forest fires or burning fossil fuels
8 which cause smog (smoke fog)
Fossil fuels are made of hydrocarbons. these are burned incompletely
In the air they react with Nitrogen to form Nitrogen oxides.
Nitrogen oxides react in the presence of sunlight to make ozone and smog
Nitrous oxides and sulfur oxides can also combine with water to form acids making acid rain
9 The result
Air pollution causes allergies asthma lung diseases like bronchitis dizziness and headaches
Ozone depletion contributes to global warming increased skin cancer (and early signs of aging)
10 (and we thought Shackleton had problems then!) 11 Sowhat do we do
