Virtual Volcano Lab Name_______________Hr___ Log onto the Discovery Channel’s Virtual Volcano site (http://kids.discovery.com/games/build-play/volcano-explorer) Global Perspectives (see the Menu on the left side) --Using the topic menu in the lower right corner, read about: 1) Tectonic Plates: Where are most of the active volcanoes found? __________________ 2) The Ring of Fire: Where is the Ring of Fire located? ___________________________ 3) The Layers Within: How do volcanoes form? _________________________________ __________________________________________________________________ Volcano Types (yup…back to the Menu on the left side) For each of the three volcano types answer the following questions… 1) Stratovolcano: a. How are they made? ______________________________________________ ______________________________________________________________ b. Look like--______________________________________________________ c. This volcano in Italy was responsible for destroying Pompeii in 79 AD--_________ d. A well-known stratovolcano in the U.S.—________________________________ 2) Cinder Cone Volcano: a. How are they made? ______________________________________________ b. Look like—______________________________________________________ c. 2 famous cinder cone volcanoes & where they are located: i. _________________________________________________________ ii. _________________________________________________________ 3) Shield Volcano: a. How are they made?_______________________________________________ b. Look like—______________________________________________________ c. A famous shield volcano & where it’s located: ____________________________ 4) Which type of volcano is the following? (Stratovolcano, Cinder Cone, or Shield volcano) a. Most violent eruptions: ___________________ b. Island builders: ___________________ c. Smallest: ___________________ Inside a Volcano (Left side. Menu…) In the space below draw a side view of what a volcano looks like on the inside and label its parts. Build Your Own Volcano… (Of course, don’t forget to watch it erupt—way cool!) --But first… 1) Select and learn about the Gas Content a. List 2 factors that can affect the explosiveness of a volcanic eruption. i. ________________________ ii. __________________________ b. Magma’s gas content usually depends on ____________________________ __________________________________________________________ 2) Select and learn about Viscosity a. What is it? __________________________________________________ b. Thick magmas tend to have _________ ___________ levels, and runny lavas tend to have _________ ___________ levels. 3) After playing with the settings on your own a bit, build the volcanoes with the settings below and record the results you create! (don’t forget to click “set conditions” before erupting). #8 is a combination for you to figure out…make a new combination. Gas Type of Viscosity Content Volcano type Eruption Other information 1. Low Low 2. High Low 3. Low High 4. One level UP from Low Low 5. Two levels UP from Low Low 6. Two levels Up from Low High 7. High High 8.
