What are the two important traits that characterize volcanoes?
______in the magma determine whether the eruption will be explosive or nonexplosive.
______is the measure of a substance’s ability to resist flow.
Part 6: Make your own Volcano?
Try all the variations of gases and silica levels along with the different types of volcanoes. Which combination of gases, silica, and volcano type creates the biggest eruption? Why does it create the biggest eruption?
What was your favorite volcano and why?
Read each case study. Which volcano is the most active? Which is the least active?
Why do we not feel most of the thousands of earthquakes that occur every year?
Where do most of the earthquakes occur in the world? In the United States?
Do the fly over of the San Andreas Fault. What type of plate boundary is this?
How do scientists find the epicenter of an earthquake?
What do scientists do to predict oncoming earthquakes?
Trigger the earthquake. How many seismograph readings do you need to find the epicenter.
Try all the variations of ground type and magnitude and create all six earthquakes. Which one produced the most damage? Why do you think it produced the most damage?
Pick one of the six case studies. Record the location of the earthquake you picked. How does the location of the earthquake relate to how many deaths happened during this earthquake? (Hint: Read the information in the section to help you).
