On this website, Starting Point Teaching Collection explains the Distribution of Active Volcanoes exercise. This worksheet is intended to direct students working independently in a 6-week exercise on volcanoes within an online geology course. The exercise consists of a series of questions plus helpful links and a map. The students collect and plot data, then interpret the results and answer questions ... Full description.

This site describes where volcanoes are found in terms of plate tectonics and explains why they occur at those locations. S map shows that volcanoes are located mainly at plate boundaries. Then there are explanations for plate motion, mantle convection, and magma generation. The three types of plate boundaries are listed as divergent, convergent, and transform. There is also information about the ... Full description.

Until recently, people living in a volcano's shadow had little help in predicting eruptions. In the past 300 years, volcanic eruptions, most of them unexpected, have killed more than 250,000 people. In 2000, experts estimated that 500 million people were living in areas at risk from catastrophic volcanic eruptions. This illustrated essay describes the strides scientists have made in eruption forecasting ... Full description.

This Why Files short article discusses some new research on Yellowstone Caldera, a giant volcanic hotspot in Wyoming. Rock has been remelted inside the caldera. Using highly sensitive techniques to extract data from almost microscopic zircon crystals, two geologists at the University of Wisconsin-Madison found that over the past 2 million years, the giant Yellowstone volcano erupted at 700,000-year ...

Since the Hawaiian Islands were all created by volcanic activity, it is somewhat surprising that only the island of Hawaii now possesses any active volcanoes. Why did the volcanoes that built the other islands stop erupting and why are those on the big island still active? This video segment, adapted from a NOVA television broadcast, shows how plumes of hot material rise from the Earth's interior ... Full description.

Students can learn how an earth scientist studies volcanic rocks by first visiting volcanoes to get a closer look and to collect rock samples, and by recreating the conditions of a magma chamber in the lab. The gas in a bottle of soda is used as an analogy to explain why some eruptions are explosive. The scientist starts by collecting pumice, a light rock filled with holes like a sponge, because it ...

This activity is an active simulation of an explosive volcanic eruption. The model volcano is a plastic 35 mm film cannister that erupts (the lid blows off) when gas pressure generated by dissolving alka seltzer is sufficiently high. It is realistic in that the timing of the eruption is difficult to predict precisely and in that the eruption occurs when the pressure of the gas exceeds the confining ... Full description.

Eruption! is a volcanic crisis simulation model that showcases a series of villages that surround an active volcano and is part of the Interactive Models for Geological Education Online (IMGEO) series. The goal of the exercise is to preserve as many people and as much property as possible in spite of the threat from the volcano. Students role-play as villagers, the governor, volcanologists, and the ... Full description.

This text reports on the experiences of a science teacher who joined a research expedition to study deep sea vents in the Pacific Ocean. It offers an engaging and informative overview of topics including the peaks, valleys, and plains that form the floor of the ocean and the internal heat that cracks the crust and causes it to move along plate boundaries. It also explains why submarine volcanoes form ... Full description.
