This chapter describes the technique of preparing latitude-longitude based data so that it can be imported into a geographic information system (GIS). It describes the steps to create a map to display data and guides users through some basic geographic analyses. The focus of the chapter?s case study is earthquake prediction. Users download and format near real-time and historical earthquake data from ... Full description.

Step-by-step instructions walk users through working with data from a seismic wave model in a freely available GIS (geographic information system) program, ESRI's ArcVoyager SE. Users generate and examine maps and produce graphs to explore variations in seismic wave velocities at depths of 28 and 100 km below Earth's surface. By examining and analyzing GIS-ready data, users visualize density changes ... Full description.

This site contains a series of visualizations of the sun, moon and Earth System and how they relate to the changing face of the moon. Animations are in the form of Java applets, forms for field observation of the moon, and a collection of exercises and PDF versions of background material. There are practice questions and quizzes that discuss the animations. Full description.

This site features Flash, QuickTime, and GIF animations that illustrate the cause of seasons, how seasons impact the sun's apparent path across the Earth's sky, the subsolar point, and the circle of illumination. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities. Full description.

This resource is a webpage that accompanies a course on asbestos in building materials. Topics include an introduction to the polarized light microscope, mineral habit, the refractive index, color and pleochroism, polarized light, birefringence, retardation and interference colors, extinction angles, and visual estimation of mineral percentages. The website features instructive photographs of thin ... Full description.

This tutorial is part of the series of investigations and visualizations on the "Exploring Earth" website, which was designed to accompany "Earth Science," a high school textbook. This tutorial on stress covers brittle and ductile deformation, stress simulations, and geologic structures. Very clear animations and field photographs illustrate this tutorial. Students can move the cursor over each photograph ... Full description.

This interactive map tool enables students and scientists to better understand the relationships between geophysical and geological processes, structures, and measurements with high-precision GPS data. It contains prepared images taken from the Jules Verne Voyager. Users can choose from a variety of base maps, add a number of geographic and geophysical overlays (e.g. plate boundaries, earthquake and ... Full description.

This site provides access to a number of visual resources and supporting material illustrating the concept of radioactive decay and its central role in radiometric dating. Visualizations include diagrams, graphs, static illustrations and photos. Resources found on this site are suitable for use in lectures and classes and may also be used as the basis for labs or other activities. Full description.

The Moon Phases java applet provides an animated view of the moon, either from Earth, or from above the ecliptic. The animation changes phases and can be seen from a top view, earth view or both. The page also provides vocabulary terms for each of the phases and other interesting information. Full description.
