Volcano Types
Scroll down to “VOLCANO TYPES” then click on “STRATOVOLCANO” in the bottom right corner
9. Use Google and define viscosity: (pick the definition that makes the most sense to you)
10. What are stratovolcanoes (composite) built of?
11. Are stratovolcanoes (composite) flat or steep?
12. Do stratovolcanoes (composite) erupt violently or quietly?
13. What are two well known stratovolcanoes (composite)?
Click on “CINDER CONE” in the bottom right corner
14. Are cinder cones volcanoes small or large in size?
15. Are cinder cone volcanoes steep or flat volcanoes?
16. What are cinder cone volcanoes made of????
17. What are two examples of cinder cone volcanoes?

23. Considering what you learned; rank the 3 types of volcanoes from smallest to largest:
24. Considering what you learned; rank the 3 types of volcanoes from flattest to steepest:
Gas and Viscosity Settings
Scroll down to “GAS AND VISCOSITY SETTINGS” then click on “ENTER”. Then on the left hand side,
click on “BUIL YOUR OWN VOLCANO AND WATCH IT ERUPT”
25. (complete the sentence) The magmas viscosity or_________________________________________ indication
of______________________________________________________________________________________
Click on “GAS INFO” below
26. What gases are dissolved in magma or volcanoes?
27. Do you think gases make a volcanic eruption explosive and violent or quiet and non-explosive?
Click on “VISCOSITY INFO” below
28. What is the magma’s viscosity or thickness and indication of????
29. What do thick magma’s tend to have more of????
30. Runny, fluid lavas tend to have low levels of what???
31. Set the both levels of viscosity and gas to low. DO NOT click on “set conditions”. You just created a shield type eruption. Look at the magma,
is flowing faster or slower???? Does it have more or less gas bubbles????
32. Scroll down to Eruption 1: Shield Eruption then click on “start eruption”. What type of eruption took place??? Was it explosive or nonexplosive? Describe the shape of the volcano; is it gentle sloping or steep??? Is it Wide or Narrow; tall or flat?
33. Scroll Back up to the GAS AND VISCOSITY SETTINGS. Now, set the both levels of viscosity and gas to high. Be careful!! DO NOT click on
“set conditions”. Look at the magma, is flowing faster or slower???? Does it have more or less gas bubbles????
34. Scroll down to Eruption 2: Strato Cone Eruption then click on “start eruption”. What type of eruption took place??? Was it explosive or
non-explosive? Describe the shape of the volcano; is it gentle sloping or steep??? Is it Wide or Narrow; tall or flat ?
