Geology Daily Warm-Up Although Kilauea usually erupts in a gentle manner, what risks might you encounter if you lived nearby?

Geology Daily Warm-Up Label the diagram with the following terms: conduit, vent, bombs, lava, parasitic cone, pyroclastic material.

Geology Daily Warm-Up If your family had to live next to a volcano, would you rather it be a shield, cinder cone, or composite volcano? Explain.

Geology Daily Warm-Up What do lahars and pyroclastic flows have in common? What is the best strategy for avoiding their worst effects?

Geology Daily Warm-Up The accompanying diagram shows one of the tectonic settings where volcanism is a dominant process. Name the tectonic setting and briefly explain how magma is generated in this setting.

Geology Daily Warm-Up Match each of these volcanic regions with one of the three zones of volcanism (convergent plate boundaries, divergent plate boundaries, or intraplate volcanism): Crater Lake Hawaii’s Kilauea Mount St. Helens East Africa Rift Yellowstone Vesuvius Deccan Plateau Mount Etna

Geology Daily Warm-Up Examine the accompanying photo and complete the following: What type of volcano is this? What features helped you make a decision? What is the eruptive style of such volcanoes? Describe the likely composition and viscosity of the magma. Which one of the three zones of volcanism is the likely setting for this volcano? Name a city that is vulnerable to the effects of a volcano of this type.

Geology Daily Warm-Up 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: What is the source of these lavas? What causes the source rocks to melt? Describe a divergent boundary that would be associated with lava other than basalt. Why did you choose it, and what type of lava would you expect to erupt there?

Geology Daily Warm-Up Explain why volcanic activity occurs in places other than plate boundaries.

Geology Daily Warm-Up 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?

Geology Daily Warm-Up This image shows the Buddhist monastery Taung Kalat, located in central Myanmar (Burma). The monastery sits high on a sheer-sided rock made mainly of magmas that solidified in the conduit of an ancient volcano. The volcano has since been worn away. Based on this information, what volcanic structure do you think is shown in this photo? Would this volcanic structure most likely have been associated with a composite volcano or a cinder cone? Explain how you arrived at your answer.

Geology Daily Warm-Up Imagine that you are a geologist charged with the task of choosing three sites where state-of-the-art 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.

Geology Daily Warm-Up Examine the accompanying photo and name the volcanic landform identified by the white arrow.

Geology Daily Warm-Up Explain why an eruption of Mount Rainier would be considerably more destructive than the similar eruption of Mount St. Helens that occurred in 1980.

Geology Daily Warm-Up The accompanying image shows a geologist at the end of a large flow consisting of lava blocks that traveled down the flank of Mount Augustine. What is this type of flow called? What do volcanologists call the structure composed of broken lava blocks (emitting steam) visible near the summit of this volcano?
