Earthquakes, Volcanoes and Plate Tectonics Share-a-thon 55 Files

A share-a-thon is a place where teachers can voluntarily upload their files for other teachers to use. When a teacher submits a file, it is catalogued and placed into a database.


Earthquakes and Plate Boundaries
The following lab activity requires the use of the Seismic Eruption software.

Finding Epicenters
Using earthquake data, regional maps, and a drawing compass, the student will triangulate the positions of three different earthquakes and then plot their locations on a world map.

Intro to Plate Tectonics
Lab A: The year is 1915. Your name is Alfred Wegener, and you have just published a book entitled, The Origin of Continents and Oceans. In your book, you argue that some 300 million years ago, all of the continents were connected into one giant landmass.

Intro to Plate Tectonics
Lab B: The year is 1915. You are a geologist attending a conference (and vacationing!) in Italy where a German meteorologist, Alfred Wegener, has given a lecture from his new book, The Origin of Continents and Oceans.

Locating an Epicenter
In this lab, you will use seismograms from three locations to determine the epicenter of an earthquake. You will use the P- and S-wave arrival time difference to determine distance to epicenter, then use a compass to record the distance radius measured.

New Madrid Earthquake
Relative Motion Of Rocks Along A Fault: Students explore different types of faults while studying the New Madrid Earthquake. Adapted from AGI lab manual.

[Answer Sheet] Pangaea Evidence

Plotting Earthquakes
Students can use Microsoft Excel to plot the locations of the most recent earthquakes. Afterwards, they can sketch the locations of the continents to determine where and why earthquakes occur.

San Andreas Fault [slide by slide description]
Fault movement, especially at plate boundaries, is largely an underground or even underwater process hidden from our view. But the boundary between the North American and Pacific Plates interfaces in a line that runs from the Mexican border north.

Shadow Zone
Identify 3 things that happen to the P-wave as it passes through the earth: requires the use of the Seismic Eruption software.
