Reviews: Beautiful scenery abounds in this informational video about the change in landforms due to weathering and erosion. The aural quality is excellent. This is a wonderful tool for group use in classrooms or for library research by individual students.—Lisa Radmer, North Bend Elementary School, WA | School Library Journal 11/02
