From a science centred 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. 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 colour photos and illustrations; words to know; bibliography; and comprehensive index.
