In this activity, you’ll investigate dynamics in Earth’s crust that explain multiple Earth science phenomena.
An earthquake simulation activity from IRIS.
Push away from those paper seismograms and get outside to make your own earthquake waves! You're going to learn about earthquake location kinesthetically. In the activity below, you will model how earthquake waves travel through the Earth at different speeds. You also will construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel-time curve). Finally, you'll use the constructed travel-time curves to locate the epicenter of a simulated earthquake by triangulation.
You can find out a great deal of information from geologic maps — from the types of rocks that make up a rock unit to the age of those rocks and the angle at which the rock bed is tilted. By identifying fractures and fracture zones in rock, geologic maps can even tell you where known faults are located.
In this lesson, students use Geographic Information Systems (GIS) together with the tools and data from the North America Global GIS CD to investigate earthquakes, volcanoes, and population from a local to global scale.
Have you ever felt an earthquake? What was it like? Where were you? What did you do? More than 143 million people are exposed to potentially damaging shaking in the United States.
