-Parts of a volcano
-Factors that affect the explosiveness of an eruption
-Types of volcanic eruptions

The students read through information on the website to find the answers to the questions, and also complete an interactive activity where they can adjust the viscosity and the gas content of magma to see what kind of eruption will take place. The students love watching the virtual volcanoes erupt! The webquest has 15 questions total, and an answer key is included.
