Part of an on-line undergraduate Physical Geology course offered at the University of Houston, this six-week long exercise asks students to gather, chart, interpret and synthesize data on current volcanic events. A brief role playing activity and virtual field trip concludes the exercise. Full description.

This homework exercise, which builds on knowledge gained in previous homework exercises located at the same site, asks students in an undergraduate class at Tulane University to answer some basic questions about volcanoes, and to determine the volcanic hazards associated with Mt. Rainier, Washington; Montserrat, West Indies; and Long Valley Caldera, California by searching the World Wide Web. Full description.

This is the Image for Magnetopause-to-Auroral Global Exploration (IMAGE) archive of weekly math, science, reading and art problems. New problems involving near-Earth space technology are emailed to participating teachers each week on Tuesday. The problems can be used in related lessons or as extra credit assignments. This web page is part of the outreach program of the IMAGE Satellite team to give ... Full description.

This homework exercise about severe weather asks students in an undergraduate geology course at Tulane University to use an on-line hurricane-tracking map to plot hurricane coordinates and to answer questions about storm surge and wind speed. Students are also asked to visit some Internet sites and answer questions about tornadoes. Full description.

This exercise is designed to explore the nature of floods and flood prediction. Prediction of flooding relies heavily upon statistical techniques based on historical records of stream behavior. This series of exercises first reviews basic concepts in flood prediction such as calculating the Recurrence Interval (RI), which is the average interval in years between occurrences of two discharges of equal ...

This problem set, which was developed for an undergraduate level geology course at Tulane University, helps students become familiar with the various types of natural disaster information available on the World Wide Web. Full description.

This website hosts over fifty practice questions relating geophysics. Topics covered in these questions include gravity, earthquake waves and seismicity, Earth's structure, geochronology, anomalies, viscosity, and polar wandering. Full description.

This homework exercise, which was designed for an undergraduate level geology class at Tulane University, asks the student to make evaluations about the Loma Prieta Earthquake and other earthquakes using seismograms, time travel curves, maps and other information. Full description.

In this activity, students examine a seismogram display called a seismic record section in which each trace is a seismogram recorded at a specific seismograph station. The seismograms are plotted according to the distance (in degrees, geocentric angle) from the earthquake location and time from the earthquake origin. The traces are of the vertical component of ground motion, and have been filtered ... Full description.

The questions on this site come from the 2000, 2001, 2002 and 2003 Virginia State Standards of Learning tests. Although explanations have not yet been written for every question, they are currently being written for the most frequently incorrectly answered questions. The Virginia Department of Education assigns a description to each test question that indicates what skill a particular question is ... Full description.
