This week we will look at ozone depletion, hence, this session should help you visualize the material that you have read so far.
View the dissipation of the ozone hole. Go to http://zebu.uoregon.edu/energy.html and click on ozone depletion. You can also jump over to http://zebu.uoregon.edu/1997/ph161/l15.html for an interesting view.
Go down to the bottom of the page compare the seasonal pattern.
How did this experience affect your knowledge about and attitudes toward the ozone hole?
