What the Earth’s atmosphere?
layer of gases surrounding planet Earth
What are the functions of Earth’s atmosphere
absorbs UV radiation from the sun
retains heat
protects life on earth

thermosphere
Which layer of the atmosphere absorbs much of the solar radiation
thermosphere
Where are the Auroras located
in the thermosphere
What causes the Auroras
when UV radiation causes ionization in the thermosphere

the exosphere
Which layer has no clear boundary to outerspace
exosphere
In the exosphere, atoms and molecules…..
escape into space

in the exosphere
What causes air pollution
chemicals
particulates
biological matter
What are air pollutants
substances that cause air pollution
can be solid, liquid, or gas
natural or man made
Primary pollutants
directly emitted from process of source
Secondary pollutants
form in the air from interaction of primary pollutants
Common air polllutants
sulfur oxides nitrogen oxides carbon monoxide carbon dioxide volatile organic compounds particulates chloroflurocarbons ammonia
