Exam 5: Volcanoes and Volcanic Hazards

The ring of fire is a narrow zone of composite cone volcanoes rimming the ________ Ocean.

You are in charge of emergency planning in Electron, Washington, when it is brought to your attention that the entire town is built upon the remains of eruption materials from Mount Rainier, which is less than 30 miles away.Using the past volcanic hazard history of Mount Rainier, which volcanic hazard would most likely affect your town?

Which of the following statements about lava domes is true?

Based on the structure of the cone and the rock making it up, what interpretations can be made about the gas content of eruptions from cinder cone volcanoes compared to those of shield volcanoes?

With the exception of volcanoes associated with a subduction zone, most volcanic islands are ________ volcanoes.

When Eyjafjallajökull erupted in March 2010, ash plumes drifted southeast over Europe and, as a result, the controlled airspaces over many European countries were closed to air traffic, stranding thousands of people worldwide.Why would flying a commercial jet through a cloud of volcanic ash be dangerous?

What kind(s)of lava generate a cinder cone?

Secondary vents on composite cones can generate ________ volcanoes.

Using the choices below, select the statement that best explains how dissolved gases drive volcanic eruptions.

What kind of volcano is this?

What kind of volcanic hazard can be triggered by the collapse of a lava dome?

Kilauea is a volcano created by ________.

What material makes up the flanks of cinder cones? Why does magma rising through the conduit of a cinder cone volcano often break through the side of the volcano and flow down the flank?

What is the difference between a pyroclastic flow and a pyroclastic surge (aka surges)?

Most cinder cones have eruptive phases that last for centuries.

The volcanic islands visible here formed as a result of a mantle plume.Which volcanic island is still forming?

Which of the following eruptive materials can be associated with cinder cone volcanoes?

Differentiate the three types of magma based on igneous composition and silica content.

Composite cones are also known as stratovolcanoes.

Based on the eruptive materials, volcanic hazards, and violence of eruptions, which type of volcano would be the most dangerous to live near? Cite specific hazards and how they could affect nearby residents.
