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 b. Hawaiis Kilauea c. Mount St. Helens d. East African Rift e. Yellowstone f. Vesuvius g. Deccan Plateau h. Mount Etna

. Examine the accompanying photo and complete the following: a. What type of volcano is it? What features helped you make a decision? b. What is the eruptive style of such volcanoes? Describe the likely composition and viscosity of the magma. c. Which one of the three zones of volcanism is the likely

Earth Science 13
Divergent boundaries, such as the Mid-Atlantic ridge, are characterized by outpourings of basaltic lava. Answer the following questions about divergent boundaries and their associated lavas: a. What is the source of these lavas? b. What causes the source rocks to melt? c. Describe a divergent boundar

Earth Science 13
Explain why volcanic activity occurs in places other than plate boundaries.

Earth Science 13
For each of the accompanying four sketches, identify the geologic setting (zone of volcanism). Which of these settings will most likely generate explosive eruptions? Which will produce outpouring of fluid basaltic lavas?

Earth Science 13
Assume you want to monitor a volcano that has erupted several times in the recent past, but appears to be quiet now. How might you determine if magma were actually moving through the crust beneath the volcano? Suggest at least two phenomena you would observe or measure

Earth Science 13
Imagine you are a geologist charged with the task of choosing three sites where state-of-theart volcano monitoring systems will be deployed. The sites can be anywhere in the world, but the budget and number of experts you can employ to oversee the operations are limited. What criteria would you use t

Earth Science 13
Explain why an eruption of Mount Rainier, similar to the one that occurred at Mount St. Helens in 1980, would be considerably more destructive.

Earth Science 13
Each statement describes how an intrusive feature appears when exposed at Earths surface by erosion. Name the feature. a. A dome-shaped mountainous structure flanked by upturned layers of sedimentary rocks. b. A vertical wall-like feature a few meters wide and hundreds of meters long. c. A huge expan

During a field trip with your geology class you visit an exposure of rock layers similar to the one sketched here. A fellow student suggests that the layer of basalt is a sill. You, however, disagree. Why do you think the other student is incorrect? What is a more likely explanation for the basalt la
