Where weather occurs
Second layer - 17-50 km

Allows for life to survive
UV radiation - wavelength to quick to be seen
Infrared radiation - wavelength to slow to be seen
What can we do?
smoke and harmeful materials that are added to the air
created by the use of fossil fuels
sunlight chemically reacts to fumes from gasoline, car exaust, and other gases
increase pollution have added to the greenhouse gases
produced at a quicker rate than natural
causing the planet to heat more than usual
Environmental Protection Agency (EPA)
