GEO 303 Volcano Exercise

Answers to the following questions are located at the home page

Volcano World http://volcano.und.nodak.edu/
The site is linked to our Geo303 web page.

Instructions:

With one or two other members of your lab:

• Open the link to Volcano World
• Choose "Volcanoes of the World"
• Choose "What's Erupting Now"
• Click on one of the red triangles.

Answer these questions on a piece of paper. It is best to turn it in before you leave lab.

1. List the names of your partners on the paper.
2. What is the name of the volcano or eruption?
3. What activity is recorded, and when? Is it active now?
4. In a sentence, cite an interesting or important feature of the activity or eruption.
5. Now, consult the map on the wall of your lab room, "This Dynamic Planet," and choose the geologic setting of the eruption. Is it:
   • on a ridge (a divergent plate boundary indicated by a solid red line)?
   • near a trench (a band of quakes, some of them deep, near or at an ocean margin, forming a convergent plate boundary)?
   • or not near either a ridge or trench, but well within a plate (like Hawaii)?
   • or is there no clear choice, and if not, briefly tell why?
