Infer Why does the Soufrière Hills volcano erupt so explosively?
Compare and contrast composite and cinder cone volcanoes.
Explain how the composition of magma can affect the way a volcano erupts.
Evaluate What factors determine an earthquake's intensity on the modified Mercalli scale?
Compare and contrast magnitude and intensity.
Make Models Select one of the three forms of volcanoes and make a model, using appropriate materials.
Draw Conclusions You are flying over an area that has just experienced an earthquake. You see that most of the buildings are damaged or destroyed and much of the surrounding countryside is disrupted. What level of intensity would you conclude for this earthquake?
Concept Map Copy and complete this concept map on examples of features produced along plate boundaries. Use the following terms: Mid-Atlantic Ridge, Soufrière Hills volcano, divergent, San Andreas Fault, convergent, and transform.
Oral Presentation Research the earthquake or volcano history of your state or community. Find out how long ago your area experienced earthquake- or volcanorelated problems. Present your findings in a speech to your class.
Earthquake Epicenter If a P-wave arrives at a seismograph station at 9:07 AM and the $S$-wave arrives at the same seismograph station at 9:09 AM, about how far is that station from the epicenter of the earthquake?
Arrival Time A seismograph station is $2,500 \mathrm{~km}$ from the epicenter of an earthquake. What is the difference in time between the $P$-wave arrival time and the S-wave arrival time?
