From a science-centered perspective, this new resource focuses on the physical and geological aspects, structure and features of 24 of earth's landforms -- what they are, how they look, how they were created, how they change over time, and major geological events associated with them. Written for middle school students to support earth science and landform-related assignments, alphabetically arranged entries follow a standard and consistent subheaded format; range in length from nine to 11 pages; and cover common and unusual landforms such as canyon, cliff, plateau, valley, volcano and many more. Entries include a description and overview of physical features or characteristics and their relationship to connected areas; how the landform is shaped including constructive and destructive forces involved and additional changes that can occur; types of life supported; and famous examples of landforms. Included are 25 maps, charts and graphs; 180 full-color photos and illustrations; words to know; bibliography; and comprehensive index.
