Volcanoes- Where and Why?

QQ- What is the difference between a seismogram and a seismograph?

I checked the homework then we spent a considerable amount of time taking notes about the difference between high SiO2 and low SiO2 lava and the types of volcanoes they form.  We also completed the Volcanoes: Where and Why? activity.

The last :20 minutes we finished watching SuperVolcano!
