After reading Chapter 3, you should be able to:
- Construct a general model of the atmosphere based on
composition, temperature, and function, and diagram this model
in a simple sketch.
- List the stable components of the modern atmosphere and their
relative percentage contributions by volume and describe each.
- Describe conditions within the stratosphere; specifically, review
the function and status of the ozonosphere (ozone layer).
- Distinguish between natural and anthropogenic variable gases and
materials in the lower atmosphere.
- Describe the sources and effects of carbon monoxide, nitrogen
dioxide, and sulfer dioxide, and construct a simple equation that
illustrates photochemical reactions that produce ozone,
peroxyacetyl nitrates, nitric acid, and sulfuric acid.
