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 b. Hawaii's Kilauea c. Mount St. Helens d. East African Rift e. Yellowstone f. Vesuvius g. Deccan Plateau h. Mount Etna
Problem 4
Explain why volcanic activity occurs in places other than plate boundaries.
Problem 6
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.
Problem 7
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 to select these sites? List some potential choices and your reasons for considering them.
Problem 9
Each statement describes how an intrusive feature appears when exposed at Earth's 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 expanse of granitic rock forming a mountainous terrain tens of kilometers wide. d. A relatively thin layer of basalt sandwiched between layers of sedimentary rocks exposed on the side of a canyon.
