Animations, illustrations, photographs, and narration guide students through each topic. They can also take a Physiographic Province Tour that simulates a flight over 42 select destinations in the U.S., including national parks, monuments, and other points of interest. Web site links are provided for each national park. After the tour, students can experiment with the slope and saturation of a hillside to make it fail, build their own river, and discover how Earth’s climate is affected by changing the tilt of its axis and the shape of its orbit around the Sun. Topics covered on this CD-ROM include weathering and soils, hillslopes, rivers, coastlines, groundwater, deserts and winds, and glaciers and climate.System RequirementsMac: PowerPC or better, OS 8.1 to OS X, 32MB RAMWindows: Pentium 120 or better, Windows 95/98/NT/2000/XP, 32MB RAM
