This site provides a brief overview of the properties associated with the atmosphere, the thin envelope of air that surrounds our planet and is a mixture of gases, each with its own physical properties. It will help students to recognize that while ninety nine percent of the atmosphere is made up of nitrogen and oxygen, the rest is made up of trace gases that can have a large impact on atmospheric processes. The site serves as a reference for and includes links to seven classroom activities.
