UPDATED to include KEY. 4-page handout/activity to summarize key concepts about Earth's atmosphere. Diagrams to print are included, and these can be used for student stations or as a whole group lesson (I prefer stations, but that's just me). Students may need to do a little internet research as well to complete all of the questions. Includes concepts such as atmosphere composition & structure, global circulation patterns, monsoons, air masses & fronts, and the atmosphere's affect on climate. If you're feeling short on time, this is a great way to get a lot into a relatively short period of time. Check out my water resources and el nino webquests to go along with this.
