Part A -  Objectives/ Guide Questions

1. Identify and discuss the layers of the atmosphere including distance from the earth, average temperature, thickness, and composition.


2. Describe the effects of air pollutants upon plant/animal species.


3. The EPA indicated the four most dangerous indoor air pollutants are; cigarette smoke, formaldehyde, radon-222, ultra-fine particulates. Identify their sources and how to reduce or eliminate their effect.


4. Given the eight major types of outdoor air pollutants identify the source, effects, and diseases associated with air pollution.
