Volcanoes
This activity uses the website for the U.S. Geological Hazards Survey Program on-line. When you get to the pages you will find the links to click on to.
Answers are provided to the questions, but these are only accessible from this page. Students should start directly on the activity page.
One way of making this web activity particularly useful is by suggesting that the students answer the questions fully. Then they could create mini case studies.
