In this activity, students use Real-Time earthquake and volcano data from the Internet to explore the relationship between earthquakes, plate tectonics, and volcanoes. Students will: Use Real-Time data to solve a problem, study the correlation between earthquakes and tectonic plates, and determine whether or not there is a relationship between volcanoes and plate boundaries. As a result of the activities, students should develop an understanding of change, constancy and measurement. Topics include: earthquakes, volcanoes, plate tectonics, plate boundaries, latitude, longitude, coordinates, Richter Scale, and epicenter.
