Problem 1
Match each of these volcanic regions with one of the three zones of volcanism (convergent plate boundaries, divergent plate boundaries, or intraplate volcanism): a. Crater Lake e. Yellowstone b. Hawaii's Kilauea f. Mount Pelée c. Mount St. Helens g. Deccan Plateau d. East African Rift h. Mount Fujiyama
Problem 3
Answer the following questions about divergent boundaries, such as the Mid- Atlantic Ridge, and their associated lavas: a. Divergent boundaries are characterized by outpourings of what type of lava: andesitic, basaltic lava, or rhyolitic? b. What is the source of these lavas? c. What causes the source rocks to melt?
Problem 6
You have just inherited a nice cottage with a beautiful view marked by volcanoes in the distance, about 20 miles away. You like the place, but you are not sure you should keep it. What are the risks of inhabiting this place?
Problem 8
Assume that you are monitoring a volcano that has erupted several times in the recent past but appears to be quiet now. How might you determine whether magma is actually moving through the crust beneath the volcano? Suggest at least two phenomena you would observe or measure.
Problem 9
The formula for the volume of a cone is \(V=1 / 3 \pi r^{2} h\) (where \(V=\) volume, \(\pi=3.14 r=\) radius, and \(h=\) height \() .\) If Mauna Loa is 9 kilometers high and has a radius of roughly 85 kilometers, what is its total volume?
