Google Earth: U.S. Volcanoes and Plate Tectonics In order to complete this exercise, you will need a computer with Google Earth. This software can be downloaded to your personal computer for free. All answers must be typed on this document. structions for creating a 2-la of volcanoes and 1. Open Google Earth on your computer. 2. open "Global Volcanism Program Holocene Volcanoes 3. Open The US GeologicaLSurvey Google Earth KML page. Then scroll down and click on "Tectonic Plate Boundaries' You have now created a GIS map of two layers: plate tectonic boundaries and volcanoes. If by any chance you do not see both, make sure that boxes are both are checked under Places'. Note: You will need to zoom in to see the volcano markers.) Part I-The Cascade Range In the Search (or Fly To Box at the very upper left of your screen, type "Cascade Range Along what type of plate boundary has this mountain range formed? (see pp 222-223 in text) What is the tectonic term for this type of volcanic mountain range Find Mt. Rainier, Washington. Click on its marker to open the Smithsonian Global Volcanism Program (SIGVP) information page. What type of volcano is Mt. Rainier? How high is Mt. Rainier? What major city is located near Mt. Rainier? Click on "Mt. Rainier, then the Smithsonian Volcano Information link at the bottom of the window. Now click on the 'Photo Gallery' tab beneath the picture. Examine several of the photographs showing the shape and size of Mt. Rainier. Answer the following questions: If Mt. Rainier were to erupt, describe the style of eruption you would expect, quiescent or explosive? (see pp. 279-281 in text) Why?

Explanation / Answer

Cascade range is a continent- oceanic convergent plate boundary in which the Juan De fuca which is an oceanic plate subducts beneath the continental plate North American plate. Cascade is a chain of volcano formed on the overriding continental plate.

Cascade range is an continental arc formed by the subduction of Juan de Fuca ,an oceanic plate beneath the overriding North American plate( continental plate).

Mt Rainier is a stratovolcano and is found in Cascades volcanic range. It is formed from the subduction of Juan de Fuca and the North American range.

Mt Rainier is the highest mountain of cascades volcanic range. It has an elevation of about 14,411 feet.

The Mount Rainier is located near the southeastern Seattle, Washington in the United States of America.

the style of eruption of Mount Rainier is mixed consists of both quiescent and eruptive phases since it is a stratovolcano which is made both of pyroclastic and lava flows.
