Earth's Dynamic Surface 1.1 is a useful tool for developing an understanding of the processes that shape Earth's surface. In this exciting CD-ROM, you are guided through each concept with full color animations, illustrations, and photographs while listening to the author's narration. Review sections at the end of each chapter will reinforce the concepts covered. Interactive activities encourage participation and problem solving. In addition, the animated Physiographic Province Tour enables you to travel to destinations across the U.S. The tour stops at 42 national parks, monuments, and points of interest demonstrating examples of each process of change introduced in the program while offering web site links to each national park.
